ONF spins out Ananki, a start-up focused on private 5G

The Open Networking Foundation (ONF) launched Ananki, an independent venture-backed company to deliver open source-based Software-Defined Private 5G as a commercial service to address enterprises’ unique requirements of Industry 4.0. The ambition is to enable enterprise private 5G that is hardened and optimized for industrial applications, yet as easy to consume as Wi-Fi.

Ananki’s technological foundation is ONF’s open source Aether, SD-RAN, SD-Fabric and SD-Core projects. The company will offer a private 5G solution delivered as a SaaS. 



Key attributes:

  • Optimized 5G+ Experience - Software-defined, automated, AI powered, application optimized connectivity, with enhanced security enabled by a programmable data plane 
  • Cloud First - pre-integrated with hyperscaler cloud and edge, delivering private 5G as a SaaS service, creating a continuously improving experience running on any multi-cloud platform
  • Industry 4.0 Ready - Empowering developers to build transformative IoT, IIoT and OT solutions with rich APIs

“ONF continues to innovate in ways that magnify the power of open systems and open source across our industry. The ONF board recognizes that the lack of support for open source initiatives from commercial companies remains an inhibiting factor for scaled adoption. To meet this challenge, we have agreed to spin out Ananki as an independent company to pursue commercialization of Aether with a view that this will help accelerate the adoption and impact of open source,” states Andre Fuetsch, ONF Board Chair and AT&T CTO.

Guru Parulkar, Executive Director ONF and CEO of Ananki, comments: “Ananki is broadening the impact of the ONF’s work, and will help ONF’s Aether become much more broadly adopted.  By providing a commercially supported option for consuming Aether, many more organizations will be able to easily and economically leverage the benefits of Private 5G for building Industry 4.0 solutions.  And in turn, Ananki is committed to contributing back to the ONF open source, helping to advance the Aether platform and broaden the ONF community.”

 ONF's Aether Edge Cloud selected for DARPA's Pronto Project

The Open Networking Foundation's Aether 5G Connected Edge Cloud platform is being used as the software platform for Pronto, a project backed by $30 million in DARPA funding to develop secure 5G network infrastructure. Specifically, DARPA is funding ONF to build, deploy and operate the network to support research by Cornell, Princeton and Stanford universities in the areas of network verification and closed-loop control. 

Aether (pronounced ‘ee-ther’) provides mobile connectivity and edge cloud services for distributed enterprise networks, all provisioned and managed from a centralized cloud. ONF will enhance and deploy its open source Aether software platform as the foundation for the Pronto research work, and in turn the research results will be open sourced back into Aether to help advance Aether as a platform for future secure 5G network infrastructure.

One of Pronto's goals is "to leverage network programmability to enable deep and wide network visibility, verification, and closed-loop control, giving programmers tools to build and dynamically deploy customized network functionality in a secure and reliable manner."


ONF also confirmed that it is now running a beta production deployment of Aether.  This deployment is a single unified cloud managed network interconnecting the project’s commercial partners AT&T, Ciena, Intel, Google, NTT, ONF and Telefonica. This initial deployment supports CBRS and/or 4G/LTE radio access at all sites, and is cloud managed from a shared core running in the Google public cloud.

The University campuses are being added to this Aether deployment in support of Pronto. Campus sites will be used by Pronto researchers to advance the Pronto research, serving as both a development platform and a testbed for use case experimentation. The Aether footprint is expected to grow on the university campuses as Aether’s 5G Connected Edge Cloud capabilities are leveraged both for research on additional use cases as well as for select campus operations.

“At Google Cloud, we are working closely with the telecom ecosystem to help enable 5G transformation, accelerated by the power of cloud computing. We are pleased to support the Open Networking Foundation's work to extend the availability of 5G and edge capabilities via an open source platform,” stated Shailesh Shukla, VP and GM, Networking, Google Cloud.

“Cornell is deploying Aether on campus to bring private 5G/LTE connectivity services with edge cloud capabilities into our research facilities.  We expect private 5G/LTE with connected edge cloud to become an important and integral part of our research infrastructure for many research and operational groups on the campus.  We also see the value of interconnecting a nation-wide leading infrastructure with Stanford, Princeton and ONF for collaborative research among university researchers across the country,” said David Lifka, Vice President for Information Technologies and CIO, Cornell University.

ONF launches SD-Core and SD-Fabric for private 4G/5G

The Open Networking Foundation (ONF) has launched two projects that further the open source movement for carrier and private enterprise 5G networks with functionality tied to public clouds.

SD-Core, an open source project for building a 5G/4G disaggregated mobile core optimized for emerging private 5G and enterprise use cases, starts with a pre-integrated dual-mode control plane. The SD-Core control plane simultaneously supports 5G standalone (SA), 5G non-standalone (NSA) and 4G/LTE deployments, thus optimizing for flexibility and future-proofing networks.

It leverages components of the free5GC and ONF OMEC projects, and builds on this with refactoring to add cloud-native capabilities for scale-out, resiliency, multi-cloud agility and SaaS deployment APIs. SD-Core is further structured to allow a single control plane to work with many user plane instances, thus optimizing for edge cloud deployments and for delivering enterprise private 5G from a common core running in the public cloud. 



SD-Fabric, an open source, P4-programmable hybrid cloud network fabric with the power to push customized packet processing deep into networking elements. Think of SD-Fabric as a cloud-managed, full stack, programmable network fabric for edge applications for Industry 4.0 powered by 5G. SD-Fabric can be deployed as-a-service, and exposes northbound APIs to enable developers to request advanced capabilities of the network such as load balancing, in-band telemetry, custom protocol processing, etc. SD-Fabric provides a full complement of classic connectivity functionality (such as L2, L3, Multicast and ACLs).  Hosts and applications require no modification to run on SD-Fabric, but the network is designed and controlled by SDN applications running on the edge cloud by ONOS rather than in embedded software running on all the individual switches in the network. This greatly simplifies the running of the network, and provides opportunities for the applications and the network to all be controlled by the same CI/CD DevOps stack by the same set of developers.

Introducing SD-Core and SD-Fabric for Private Mobile Networks

The Open Networking Foundation's Timon Sloane introduces SD-Core, an open-source project for building a 5G/4G disaggregated mobile core optimized for emerging private 5G and enterprise use cases.

ONF advances its Certified SDN Associate program

The Open Networking Foundation (ONF) announced a major update to its ONF Certified SDN Associate (OCSA) program, which is designed to familiarize and certify engineers with the key components of disaggregated SDN networks, from white box switching to network operating systems, northbound and southbound interfaces, P4 and next-gen SDN interfaces, open source platforms, etc. 

OCSA-2.0 reflects the rapid progress that continues to be made across the SDN industry. OCSA-2.0 updates the content and will replace the original OSCA exam to ensure that certified individuals have a strong foundation and fundamental knowledge of current and relevant networking tools, technologies and trends.  

ONF collaborates with a group of authorized training providers to offer skills training and testing with online and in-person options available worldwide.  To support those studying for the new OCSA-2.0 exam, ONF is also making new free resources available, in particular Larry Peterson’s new book: SDN, a systems approach. The book is organized around the new SDN stack, with the goal of presenting a top-to-bottom tour of SDN without leaving any significant gaps that the reader might suspect can only be filled with magic or proprietary code. Readers can complete hands-on programming exercises included at the end of the book to prove that the software stack is both accessible, robust and complete.

In addition, the ONF launched its new ONF Marketplace featuring products that have completed testing and achieved certification as part of ONF’s Continuous Certification Program. ONF’s open source platforms that are currently part of this program include Aether, Stratum, SEBA and VOLTHA.

ONF launches 5G SD-RAN Project

The Open Networking Foundation (ONF) has launched an SD-RAN project with the aim of building an open source Near Real-Time RAN Intelligent Controller (nRT-RIC) compatible with the O-RAN architecture as well ONF’s existing base cloud-native solutions leveraging disaggregation and whitebox hardware.

ONF said its goal is to foster open source software platforms and multi-vendor solutions for mobile 4G and 5G RAN deployments.

Central to the project is the development of an open source near-real time RIC called µONOS-RIC (pronounced “micro-ONOS-RIC”).

µONOS is a microservices-based SDN controller created by the refactoring and enhancement of ONOS, the leading SDN controller for operators in production tier-1 networks worldwide.  µONOS-RIC is built on µONOS, and hence features a cloud-native design supporting active-active clustering for scalability, performance and high availability along with the real-time capabilities needed for intelligent RAN control. The O-RAN ALLIANCE E2 interface is used to interface between µONOS-RIC and vendor supplied RAN RU/DU/CU RAN components.

Carriers would be able to run new "xApps" on top of the µONOS-RIC.  These open xApps could provide functionality that traditionally has been implemented in vendor-proprietary implementations, including providing visibility and control over the RAN.

Significantly, the ONF's SD-RAN project is backed by AT&T, China Mobile, China Unicom, Deutsche Telekom, Facebook, Google, Intel, NTT, Radisys and Sercomm.

A working skeleton prototype of the µONOS-RIC controller is already running above a RAN emulation platform through the E2 interface.  ONF has demonstrated handover and load balancing at scale, supporting over 100 base stations and 100,000 user devices with less than 50ms handover latency (less than 10ms latency for 99% of all handovers). Field trials are expected by early 2021.

“AT&T strongly supports the development of specifications and components that can help drive openness and innovation in the RAN ecosystem. The O-RAN ALLIANCE’s specifications are enabling the ecosystem, with a range of companies and organizations creating both open source and proprietary implementations that are bringing the open specifications to life. The ONF SD-RAN project, along with the O-RAN OSC, will expand the ecosystem with an nRT-RIC that can support xApps and help demonstrate their interoperability. This project will help accelerate the transition to an open RAN future,” stated Andre Fuetsch, President and Chief Technology Officer, AT&T Labs.

“Google is an advocate for SDN, disaggregation and open source, and we are excited to see these principles now being applied to the RAN domain. ONF’s SD-RAN project’s ambition to create an open source RIC can help invigorate innovation across the mobile domain, said Ankur Jain, Distinguished Engineer, Google.

This pilot is centrally managed and controlled from public cloud, with Aether Edge installations at each site. The entire deployment is maintained by ONF and ONF members using a distributed CI/CD DevOps development pipeline.

As with all ONF projects, Aether is backed by ONF’s operator partners AT&T, China Unicom, Comcast, Deutsche Telekom, Google, NTT Group and Turk Telekom. Additionally, ONF, Intel, GSLab, Infosys, and Accelleran are actively collaborating as a distributed DevOps team enhancing and maintaining Aether.

Radisys unveils software-defined PON architecture

Radisys introduced Connect Open Broadband, a carrier-grade, Tier 1 network-hardened, scalable and secure software-defined Passive Optical Network (PON) distribution based on open standards and web-scale architecture.


Radisys’ Connect Open Broadband offers an intelligent, scalable and secure software-defined PON distribution based on the Open Networking Foundation’s (ONF) SEBA reference platform and enhanced with Radisys innovation. This architecture allows for a seamless introduction of the Broadband Forum’s OB-BAA architecture by conforming to the standard YANG models with the Northbound Interface (NBI).

The solution disaggregates software from the underlying hardware with open interfaces, enabling faster product innovation cycles. The hardware agnostic solution enables service providers to leverage white-box optical line terminals (OLTs) from an interoperable multi-vendor ecosystem for flexible deployable options.

Connect Open Broadband, built on cloud-native microservices architecture, allows for the addition of new network functions on demand and delivers a path to automated and simplified network operation. The programmability, automation and deeper network visibility further enables better fault detection, faster service delivery and future-proof network expansions.

The solution is access network (GPON, XGS-PON, NG-PON2) agnostic and offers flexible deployment options.

“In the digital era where high-bandwidth services and pervasive connectivity are required to meet subscriber expectations, service providers are rethinking how they build their networks to meet demand with optimal performance and value,” said Harris Razak, senior vice president of Broadband Access, Radisys. “Connect Open Broadband is a commercially ready, network-hardened solution that allows service providers to enable rapid innovation through disaggregation and to bring new services to market faster.”

“Radisys has been a Partner Member of ONF for many years and has been one of the most active supply chain members working directly with our operator partners. Radisys has helped drive ONF open reference designs and open source platforms and is among the first to commercialize solutions based on ONF platforms,” said Guru Parulkar, Executive Director, ONF. “Radisys’ Connect Open Broadband combines open architectures, software innovation, and white-box hardware to facilitate service agility.”

ONF Launches Continuous Certification Program

The Open Networking Foundation (ONF) introduced a Continuous Certification Program, enabling supply chain vendors to embed their products for ongoing test and compliance certification with ONF’s open source software projects. 

The aim is to reimagine certification testing in the age of Continuous Integration (CI)/Continuous Deployment (CD) and cloud software development.

The ONF said its projects already incorporate a continuous testing framework that keeps pace with enhancements to the platform in order to facilitate CI/CD - thus enabling rapid agile software development. ONF’s new Continuous Certification (CC) Program leverages the ever evolving testing framework for each project, and inserts participant products into the CI/CD/CC pipeline such that the systems are continuously retested and certified on an hourly or daily basis.  When a formal release of the project is declared, all systems currently validated as conformant in the CI/CD/CC pipeline will be officially certified as part of the release package bill-of-materials.

Product certification in ONF’s CI/CD/CC process is not a one-time activity. Vendors provide hardware or software products for indefinite installation into the development pipeline, and their products are continually tested throughout the development process. Rather than simply publishing static and outdated results, the real time status is made available via a public dashboard highlighting each product’s current compatibility with the most recent in-development version of ONF open source software.  This is, in essence, cloud era certification.

The testing and certification process requires considerable resources. ONF is unique in that it is the only open source networking organization with a full-time engineering team, thus making implementation of this new program possible. With this program, ONF will be publishing certified hardware and software BOMs (bill-of-materials) to smooth adoption of ONF platforms and broaden the ecosystem of hardware and software components compatible with ONF software distributions.


The ONF also announced a collaboration with the Open Compute Project (OCP) to promote the use of OCP-recognized open hardware in ONF solutions. Together, this collaboration will make clear for end users how best to assemble world-class solutions leveraging both open hardware and open software components, thus driving wider adoption of comprehensive open networking solutions

“The increasing speed at which operator-driven open source and SDN network deployments has been moving over the past few years mandates a certification program that is designed to run several times faster than conventional certification processes,” said Timon Sloane, Vice President of Marketing & Ecosystem for the ONF. “The ONF is in a singular position to offer this testing, and our Continuous Certification Program is further enhanced when testing is performed by engineers who have hands-on familiarity with the ONF’s Reference Design platforms. Our Continuous Certification program is also consistent with the industry migration to cloud native testing and automation, and increases the velocity of innovation and value provided to our members.“

ONF’s Stratum Open Source Switch OS runs on TIP's Cassini

Stratum, the open-source switch operating system software developed by the ONF, is now available on Cassini packet optical transport hardware from TIP.

Cassini is a network switching platform with integrated optical transponders that is developed as a project by the Telecom Infra Project (TIP).

Stratum is a thin switch OS for data center white box switches supporting SDN interfaces, including P4, P4Runtime, gNMI and OpenConfig.



Stratum’s capabilities have now been extended to support configuration and management of optical parameters including wavelength, modulation and optical power. These new capabilities enable Stratum to be deployed on the white box Cassini platform. Stratum on Cassini now enables a completely open SDN-native solution for addressing Data Center Interconnect (DCI) use cases.

The ONF notes that its ODTN project has already demonstrated end-to-end orchestration of a network of Cassini-based systems in field trials. The demonstration leveraged the open source ONOS control plane from ONF and the open hardware from TIP; it also relied on proprietary embedded software running on the Cassini platform. It can serve both as a spine for “leaf-spine” type architectures within the datacenter, and as a packet optical transponder for the inter-datacenter connections. The four Cassini systems replace what would otherwise be 8 distinct devices: 4 spine switches and 4 packet optical transponder systems.  This converged design enables operators to deploy simpler solutions at a much lower cost, both in terms of Capex and Opex.




ONF's Stratum Project goes Open Source

The ONF's Stratum SDN project has been released as open source under the Apache 2.0 open source license.

Stratum is an open source, silicon-independent switch operating system for software-defined networks that runs on a variety of switching silicon and various whitebox switch platforms.

The ONF said the goal of Stratum is to avoid the vendor lock-in found with today’s data planes that feature proprietary silicon interfaces and closed software APIs that tend to lock operators into using a specific hardware technology. The strict contractual relationship of a P4-based interface between a Stratum switch and its controller ensure that the switch can be swapped with a spectrum of alternatives (even those with different switching silicon from a diversity of vendors) without need for controller modification or network retest and validation.  Never before has it been possible to grow and upgrade installations and adopt the latest advancements in switching silicon at the speed of cloud development.

Stratum also exposes a set of next-generation SDN interfaces including P4, P4Runtime, OpenConfig, gNMI and gNOI, enabling programmability of forwarding behaviors, zero-touch operations and full automated life-cycle management. This makes Stratum a key enabler for ONF’s next-generation SDN initiative.

“Bringing project Stratum to open source is an important milestone in furthering the ONF’s open networking movement,” said Guru Parulkar, Executive Director, ONF. “Stratum provides a consistent set of northbound Next-Gen SDN interfaces even as it runs on a wide selection of hardware platforms leveraging a variety of switching silicon. As such, Stratum is becoming the common substrate for ONF’s Next-Gen SDN stack, enabling rapid innovation, zero touch operations and a robust hardware ecosystem.”

ONF marks first deployment of Open Source Mobile Evolved Packet Core

by Benedict Chua, Assistant Editor

T-Mobile (Poland) has deployed ONF’s Open Mobile Evolved Core (OMEC) open source platform in its production network. Specifically, T-Mobile Poland is using OMEC’s gateway control, user plane and billing components to deliver a Fixed Mobile Substitution (FMS) service to its customers. The OMEC components provide all the necessary features and standard 3GPP interfaces for interconnecting to T-Mobile’s existing base stations, mobility management entities and lawful intercept platforms.

The ONF launched OMEC in 2019, making available the first production-grade, disaggregated, control-user plane separated (CUPS), 3GPP-compliant open source mobile core solution that can run on containers, virtual machines or bare metal. It provides a cornerstone for the ONF‘s COMAC (Converged Multi-Access and Core) project, developed to bring convergence to operators’ mobile and broadband access and core networks. It is based on and paired with COMAC Reference Design, which is now available for ONF Member review and feedback.

T-Mobile’s OMEC deployment highlights:

  • Complete connectivity, billing and charging capabilities
  • 3GPP Release 13 compatibility
  • Supports a large number of subscribers with a high-performance DPDK based dataplane
  • Optimized for lightweight cost-effective fixed-mobile substitution service deployments

“Our OMEC deployment provides us with a lightweight packet core providing connectivity, billing and charging at scale for a large number of fixed mobile subscribers. By taking the bold step of embracing open source as part of a new approach for building and deploying solutions, we are realizing a much lower total cost of ownership, rapid customizability, and greater transparency than we can achieve using any traditional EPC,” said Michal Sewera, head of the EPC Shared Service Center at T-Mobile Poland.

ONF said T-Mobile’s deployment demonstrates how operators and supply chain vendors who are willing to embrace open source can deploy solutions with disruptive value propositions in record time. T-Mobile Poland’s pioneering project demonstrates the tremendous value of taking an open source approach to transforming networks and paves a path for other operators to follow.

“T-Mobile Poland, supported by Deutsche Telekom as a partner of the ONF, has been at the leading edge of developing, testing, and now deploying OMEC into a production network,” said Oguz Sunay , Chief Architect for Mobile, ONF. “This successful implementation demonstrates the power of community, the maturity of open source in the telco space, and the production worthiness of OMEC.”

Broadband Forum and ONF align work on Automated and Open Virtualized Access Networks

The Broadband Forum (BBF) and the Open Networking Foundation (ONF) announced an agreement that sets forth how operators seeking to effectively use virtualization and open source to increase agility can leverage open source and standardization projects side-by-side to ease their migrations to automated access networks and enable seamless co-existence.

Specifically, the agreement sees an alignment between the BBF's Open Broadband-Broadband Access Abstraction and ONF's SDN Enabled Broadband Access (SEBA) platform.

Open Broadband-Broadband Access Abstraction (OB-BAA) is a BBF open source project that enables SDN-based management and control of multi-vendor, multi-technology access networks via a standard abstraction northbound interface. It facilitates co-existence and seamless migration, bringing the agility to adapt to a wide variety of software defined access models. This abstraction simplifies and reduces development upstream in management and control software for Physical and Virtual Network Functions (PNFs and VNFs). Inherent in the OB-BAA project is the ability to pull differing access device types, including legacy implementations, together under a single standardized network and service management & control umbrella to be exposed to management elements such as the SDN Management and Control and Element Management Systems.

ONF’s SDN Enabled Broadband Access (SEBA) platform takes a disaggregated white-box approach to building next generation access networks leveraging open source. Functionality traditionally run on chassis-based Optical Line Terminals (OLTs) and on Broadband Network Gateway (BNG) routers is run in the cloud, and the hardware is minimized to a collection of simple white-box OLTs, switches and servers. SEBA wraps together this collection of open source hardware and software into a comprehensive platform that exposes northbound FCAPS interfaces, making it straight forward to integrate a SEBA POD with an operator’s OSS/BSS system.

ONF’s Virtual OLT Hardware Abstraction (VOLTHA) open source software project abstracts a PON network to make it manageable as if it were a standard OpenFlow switch. Functionality like DHCP and user authentication is run as open source in the cloud, giving operators control over functions that have traditionally been embedded in vendor tightly integrated chassis solutions. VOLTHA is used as a component of the SEBA platform and can also be used standalone by operators wanting to leverage just the specific capabilities of access network abstraction and SDN control.

Broadband Forum and ONF said they believe that many types of carrier deployments would benefit from the capabilities offered by OB-BAA and SEBA/VOLTHA. The cooperation between the two organizations takes their work to the next level, providing an effective and efficient path for operators to leverage the innovations and benefits of both initiatives while ensuring interoperability, high performance, scalability and maximum reliability. A whitepaper providing more detail on the relationship between OB-BAA and SEBA/VOLTHA open source projects can be found here.

AT&T sees progress with ONF's SEBA, Trellis and other projects

Projects like Trellis, SEBA, OMEC, Stratum, and P4 are redefining what a modern network looks like, said Andre Fuetsch, President, AT&T Labs and Chief Technology Officer, speaking at the Open Networking Foundation’s Connect 2019 conference in Silicon Valley/

AT&T is currently using SEBA (Software-Enabled Broadband Access) to deliver gigabit-plus, low-latency home internet access via white box hardware to 500 homes in the U.S. The carrier plans to scale up in 2020 and beyond.

SEBA (SDN Enabled Broadband Access) is a lightweight virtualized broadband platform originally based on a variant of ONF’s R-CORD. It supports multiple virtualized access technologies at the edge of the carrier network (e.g. PON, G.Fast, DOCSIS), allowing each access technology to be controlled by OpenFlow. Furthermore, mediation software is provided to help operationalize the access devices and connect the SEBA implementation to OSS/BSS systems. SEBA supports both residential access and wireless backhaul and is optimized such that traffic can run ‘fastpath’ straight through to the backbone without requiring VNF processing.


Fuetsch also talked about progress with Trellis, which is seeing very deployment as well.

Trellis defines a solution for an open multi-purpose L2/L3 spine-leaf Ethernet switch fabric for edge data centers and for interconnecting multiple sites. It supports Virtualized Network Functions (VNFs) running on servers, network functions implemented directly within the switch fabric itself, and the interconnection of local and remote resources all in a single solution. Trellis builds a non-blocking fabric using OpenFlow controlled white box switching hardware and open source software. The Trellis fabric does not run any embedded control protocols on the switches (e.g. BGP, OSPF or RSTP). Instead, intelligence is moved into applications running on a clustered ONOS controller.

Comcast activates Trellis Open Source Networking Fabric

Comcast has reached production roll-out of the Trellis Open Source Network Fabric as part of Comcast’s Distributed Access Architecture (DAA) buildout. The implementation relies on whitebox-based Ethernet backhaul to improve network scalability and space/power efficiencies in the head-ends.

The announcement, which was made at the ONF Connect conference in Santa Clara, California, is a milestone in Comcast's DAA evolution and a key proof point for the ONF.

Comcast confirmed that it is now running Trellis in multiple markets and that rollouts are accelerating. 

ONF’s Trellis is an open-source, SDN based, multi-purpose spine-leaf switching fabric supporting distributed access-and-edge networks, NFV and edge cloud applications. Trellis leverages the ONOS open source SDN controller, the OpenFlow protocol and white box switches. Trellis implementations are significantly simpler and more adaptable than a conventional network that relies on embedded routing and switching protocols running on each individual switch. For example, instead of having to configure and run distributed multicast routing protocols, intelligence is centralized in Trellis and run in a cloud-native fashion on a resilient cluster of standard compute nodes.

“In collaboration with the ONF and a team of supply chain vendors, Comcast is deploying the open source Trellis platform as the networking fabric in our next generation access network,” said Elad Nafshi, Senior Vice President, Next Generation Access Networks, Comcast.  “This has been a multiple year journey from design, to extensive field trails and finally to production rollout, and we’re impressed with the results and the advantages that using open source and Trellis are delivering for us as we upgrade our access network.”

“The open source ecosystem created by ONF has collectively established a new ‘Distributed DevOps’ model through the process of trialing, hardening and deploying Trellis with Comcast.  This has established a new formula for open source whereby an operator, ONF and a consortium of commercial entities come together to collectively build and stand behind a deployment,” said Saurav Das, Vice President of Engineering for the ONF.

ONF's Stratum Project goes Open Source

The ONF's Stratum SDN project has been released as open source under the Apache 2.0 open source license.

Stratum is an open source, silicon-independent switch operating system for software-defined networks that runs on a variety of switching silicon and various whitebox switch platforms. 

The ONF said the goal of Stratum is to avoid the vendor lock-in found with today’s data planes that feature proprietary silicon interfaces and closed software APIs that tend to lock operators into using a specific hardware technology. The strict contractual relationship of a P4-based interface between a Stratum switch and its controller ensure that the switch can be swapped with a spectrum of alternatives (even those with different switching silicon from a diversity of vendors) without need for controller modification or network retest and validation.  Never before has it been possible to grow and upgrade installations and adopt the latest advancements in switching silicon at the speed of cloud development.

Stratum also exposes a set of next-generation SDN interfaces including P4, P4Runtime, OpenConfig, gNMI and gNOI, enabling programmability of forwarding behaviors, zero-touch operations and full automated life-cycle management. This makes Stratum a key enabler for ONF’s next-generation SDN initiative.

“Bringing project Stratum to open source is an important milestone in furthering the ONF’s open networking movement,” said Guru Parulkar, Executive Director, ONF. “Stratum provides a consistent set of northbound Next-Gen SDN interfaces even as it runs on a wide selection of hardware platforms leveraging a variety of switching silicon. As such, Stratum is becoming the common substrate for ONF’s Next-Gen SDN stack, enabling rapid innovation, zero touch operations and a robust hardware ecosystem.”

ONF publishes SEBA, Trellis and ODTN reference designs

The Open Networking Foundation (ONF) released its first three Reference Designs (RD’s): SEBA, Trellis and ODTN.

Each of these reference designs are backed by network operators and supported by supply chain partners. The reference designs are paired with an open source Exemplar Platform (EP).  Both the RD and EP proceed in parallel, and RDs are not released unless a paired EP is available to prove out the architecture and accelerate adoption. 

Virtualized Broadband – SEBA

SEBA (SDN Enabled Broadband Access) is a lightweight virtualized broadband platform originally based on a variant of ONF’s R-CORD. It supports multiple virtualized access technologies at the edge of the carrier network (e.g. PON, G.Fast, DOCSIS), allowing each access technology to be controlled by OpenFlow®.  Furthermore, mediation software is provided to help operationalize the access devices and connect the SEBA implementation to OSS/BSS systems.  SEBA supports both residential access and wireless backhaul and is optimized such that traffic can run ‘fastpath’ straight through to the backbone without requiring VNF processing.  See ONF Reference Design TS-100 SEBA v1.0

Optical Networking – ODTN (released as Informational)

ODTN (Open Disaggregated Transport Networking) describes a blueprint for constructing open source solutions for multi-vendor optical networks mixing transponders from multiple suppliers as well as Open Line System from yet a different source.  ODTN is being released as an “Informational” Reference Design. The ONF wants to share publicly the status of this work, but given that a paired open source Exemplar Platform is not yet available in a sufficiently mature state ready for deployment, this RD is being published as Informational.  See ONF Reference Design Info-1002 ODTN v0.4

“We are excited to see the first formal release of the ONF’s first Reference Designs.  SEBA is experiencing fantastic traction and AT&T has live field trials with additional plans to scale the network moving forward.  We are also pleased to see growth in both the developer community and in the number of interested operators,” said Eddy Barker, AVP- Design & Architecture, Converged Access Systems, AT&T Labs.

“Deutsche Telekom’s SEBA implementation called Access 4.0 creates edge data centers supporting broadband Internet using FTTH/B,” said Robert Soukup, Program Manager for DT. “This is true next generation edge access using SDN. It helps us to realize our vision on many fronts, including the case for cost reduction, increased automation, and reduced time to market. This year we are bringing the project into an extended field trial and strongly drive productization. The results benefit the entire community and this is at the heart of ONF’s mission for open source.”

ONF and TIP collaborating on Open Optical Transport

The ONF and the Telecom Infra Project (TIP) agreed to collaborate on optical transport solutions that increase openness, SDN programmability, and disaggregation.

The collaboration combines the ONF's Open Disaggregated Transport Network (ODTN) project and TIP’s­­­ Open Optical & Packet Transport(OOPT) group. Both groups are leveraging open software and hardware, common APIs and community collaboration.

The groups said their existing work as highly synergistic, as the ONF (ODTN) has pursued a software-centric approach while TIP (OOPT) has pursued an open hardware agenda. 

ONF (ODTN) will continue to focus on the control plane with the development of an Open Source SDN controller (ONOS) and standardization of open APIs such as Transport API (TAPI). ONF has also developed the definition of the end-to-end Data Center interconnect (DCI) use-case according to ONF’s service provider needs through its ODTN Reference Design process.

In parallel, TIP (OOPT) members have introduced two white box transponder systems, Voyager and Cassini, based on open designs.  They have also developed TAI, the Transponder Abstraction Interface, and the GNPy open source optical planning tool.

ONF launches Converged Multi-Access and Core Initiative

The ONF has launched a Converged Multi-Access and Core (COMAC) initiative for delivering next-generation services over both mobile and broadband networks.

The new COMAC Reference Design, which leverages the ONF’s Strategic Plan and ONF’s Reference Design working model, will enable Service Providers to program network slices combining various access and core technologies.

Carriers supporting the COMAC initiative include AT&T, China Unicom, Deutsche Telekom, Google, and Türk Telekom.


The COMAC Reference Design will specify the common requirements agreed to collaboratively by the ONF operators, and will provide a blueprint for an open source approach to address the space.

Highlights

Converged Access: COMAC access architecture is built on disaggregated RAN (leveraging the O-RAN RU/DU/CU architecture), disaggregated mobile core, and disaggregated Broadband Network Gateway (BNG) components.  Elements from each are then redistributed and aggregated into a unified access layer, creating a SDN powered control plane and P4 powered user plane that each contain elements of the RAN CU, Mobile Core and BNG.  This reformulated and highly optimized stack can thus manage high-speed subscriber traffic regardless of a user’s access link.  COMAC will offer different implementation choices for 4G & 5G RAN as well as PON, WiFi, DOCSIS and fixed wireless broadband connectivity.
Converged Core: COMAC integrates unified subscriber management, blending Mobile MME, HSS and BNG-Authentication and billing functions into a common platform that will enable operators to manage their user base as a unified whole rather than as distinct and isolated service offerings.

The COMAC Open Source Project is crafting an Exemplar Platform (EP)with the support of operators AT&T, China Unicom, Deutsche Telekom, Google Cloud, Sprint and Türk Telekom and a supply chain ecosystem including Adtran, Intel, Radisys, GSLab and HCL.

ONF begins Open Evolved Mobile Core Project

ONF is also launching an Open Mobile Evolved Core (OMEC) project, leveraging its earlier work for its Central Office Re-architected as a Data Center (CORD) initiative, and serving as an ‘upstream project’ to the newly launched COMAC project.



The OMEC project, which is being developed in collaboration with Sprint, is built using an NFV (Network Function Virtualization) architecture that is optimized for Intel platforms and tested for scale. OMEC is compliant with the 3GPP architecture, includes the following EPC and Charging components:

  • SGW-C, PGW-C (Includes embedded PCEF), SGW-U, PGW-U, MME, HSS, HSS Database, Diameter Capability, PCRF, Forwarding Policy Control SDN Controller, CTF, CDF, SGX Billing Router
  • Operational tools, including CLI, Logging and Statistics Interface APIs to VNFs
  • DPDK based traffic generator for testing S1u and Sgi user planes
  • CI/CD tools for deployment automation for bringing up core network VNFs, associated networking, package installation, provisioning, and configuration.

"Sprint is excited to be co-launching the OMEC project addressing the need for an open mobile core.  Sprint’s Clean CUPS Core for Packet Optimization (C3PO) project along with other elements are being contributed as seed code for the launch of OMEC.  We plan to conduct field trials using OMEC for edge applications this year, and we’re thrilled to be working with the ONF to build a broader community to leverage and build upon OMEC,” stated Ron Marquardt, Vice President of Technology, Sprint.
