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.





  • 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.  Fabric switches are thus simplified, and the fabric can be optimized by leveraging a holistic view of all activity while new features and functionality can be deployed without upgrading the switches.

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

NFV Fabric  – Trellis

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.  Fabric switches are thus simplified, and the fabric can be optimized by leveraging a holistic view of all activity while new features and functionality can be deployed without upgrading the switches. See ONF Reference Design TS-101 Trellis 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.

ONF Connect -- Highlights with Guru Parulkar



Guru Parulkar, Executive Director of the Open Networking Foundation (ONF), provides an overview of this week's operator-led conference in Silicon Valley, which featured presentations from ONF’s operator leadership: AT&T, China Mobile, China Unicom, Comcast, Google, Deutsche Telekom, Telefonica, NTT Group, and Turk Telekom.

A major accomplishment for 2018 was ONF's release of its initial set of open source Reference Designs, which target edge and access clouds infrastructure. These are “blueprints” for how to put common modular components together to create platforms based on open source. They leverage the ONF's prior work with CORD and M-CORD.

One big item of news from this week's conference is AT&T's announcement that it has launched the first SDN-enabled Broadband Access (SEBA) field trials in two cities with over 100 customers.

ONF Connect Keynote: AT&T 's Andre Fuetsch

It's a really exciting time at AT&T not only because of the upcoming 5G launch later this month but also because of the many other areas of innovation underway in the network, said Andre Fuetsch, CTO of AT&T and President of AT&T Labs, in a keynote address at the ONF Connect conference in Santa Clara, California.

Some highlights:

  • AT&T is actively developing the ONF Software-defined Broadband Access (SEBA) reference design. It has two field trials underway using 10 GPON technology. This marks the first field deployment of SEBA, which is expected to be an enabler of edge cloud capabilities.
  • AT&T is handling 242 petabytes of traffic per day, 53% of which is video.
  • The move to NFV/SDN began in earnest in 2014 and so far the company has virtualized 65% of its network. The stated goal is to virtualize 75% by 2020.
  • The decision to adopt whitebox switches in the network is a key differentiator for AT&T, especially as capabilities move toward the edge.
  • In 2017, AT&T announced its first field trials of whiteboxes.
  • AT&T is now ready to move forward with the deployment of 60,000 whitebox routers in cell site towers across its network.
  • These cell site whitebox gateway routers will use a software stack from AT&T's Vyatta division.
  • AT&T has published its specifications the white box cell site gateway router. This has become the basis for the Disaggregated Network Operating System (DANOS) project, which is now being hosted by the Linux Foundation. 
  • The cell site routers integrate into its Open Network Automation Project (ONAP) implementation. This is powering the 5G network.
  • AT&T is also deploying whiteboxes as top-of-rack switches in its data centers. It is also deploying whiteboxes in its global POPs, including recent installations in Singapore, Toronto, and Amsterdam.

  • AT&T is supporting the O-RAN Alliance for virtualizing the radio access network.

ONF moves ahead with reference designs

The Open Networking Foundation (ONF) announced a series of reference designs backed by ONF’s operator leadership, which includes AT&T, China Unicom, Comcast, Google, Deutsche Telekom, Telefonica, NTT Group, and Turk Telekom.

The initial set of open source Reference Designs, which target edge and access clouds infrastructure, essentially are “blueprints” for how to put common modular components together to create platforms based on open source. They leverage the ONF's prior work with CORD and M-CORD.

Another way to think of the reference designs is as "swim lanes" for assembling open source platforms for both the cloud data center infrastructure and the underlying optical transport network.

It is also interesting to note Google's presence in ONF's operator leadership ranks. In April, Google announced plans to use P4Runtime as the foundation for its next generation of data centers and wide area network control-plane programming. P4 is a programming language was designed to be target-independent (i.e. a program written in P4 could be compiled, without modification, to run on a variety of targets, such as ASICs, FPGAs, CPUs, NPUs, and GPUs), and protocol-independent (i.e. a P4 program can describe existing standard protocols, or be used to specify innovative, new, customized forwarding behaviors).  The ONF's reference design for a Unified, Programmable & Automated Network (UPAN) will use P4 as its enabling technology. If other telcos adopt the UPAN reference design, Google will be well-positioned to offer them a wholesale service running in its cloud.

In addition, ADTRAN, Dell/EMC, Edgecore Networks and Juniper Networks have joined the ONF as supply chain partners in this reference design process.

“Over the last several years, ADTRAN has fully embraced open, disaggregated and software-defined attributes as the core principles in our Mosaic-branded access focused solutions. We are encouraged by ONF’s new strategic plan and strong operator commitment and believe ADTRAN is a perfect fit as a supply chain partner,” said ADTRAN Senior Vice President of Technology and Strategy Jay Wilson. “ADTRAN intends to contribute across multiple reference design initiatives by applying access domain expertise both in software and systems integration.”



Open Disaggregated Transport Network project gets underway

A new, operator-led Open Disaggregated Transport Network (ODTN) project is underway at the Open Networking Foundation (ONF).

The goal of ODTN is to build optical transport networks using disaggregated optical equipment, open and common standards, and open source software.

The project will deliver an open source platform for running multi-vendor optical transport networks. It will leverage the ONF’s ONOS SDN Controller, automatically and transparently discovers the disaggregated components and will control the entire transport network as a unified whole, thus enabling multi-vendor choice.

The organizers of the project say that just as the SDN movement has disaggregated the data center and operator edge networks, ODTN will bring similar benefits to the optical transport network including best-of-breed choice, elimination of vendor lock-in, cost containment and accelerated innovation.

Backers of the project include China Unicom, Comcast, NTT Communications, Telefonica and TIM.

Each of the five founding operators has committed to performing lab integration and evaluation of the platform for future transport applications. Additional support is coming from leading vendors in the optical equipment space, with NEC, NOKIA, Oplink, ZTE contributing to the software platform and building full solutions, CTTC contributing from academia, and ADVA, Ciena, Coriant, CoAdna, Infinera and Lumentum participating in lab and field trials.

Relationship to Other Projects

ODTN is the only open source solution in the optical transport space, but is leveraging other ongoing work which has focused on standardizing various interfaces and components.

ODTN will leverage and expose TAPI as its northbound interface, leveraging the work coming out of the ONF’s Open Transport Configuration and Control (OTCC) project. Likewise, OpenConfig is the base southbound model and API for communicating to optical equipment.

The OpenROADM MSA defines interoperability specifications and data models for optical devices, networks and services.  ODTN benefits from this effort and, over time, it helps the industry achieve transponder compatibility.  This will eliminate the need to deploy transponders in matched pairs, further disaggregating the solution and enabling even greater deployment flexibility.

TIP’s Open Optical & Packet Transport project is producing open DWDM architectures, models and APIs, covering transponders, open line systems, and routers. In time, the ODTN project hopes to benefit from the availability of open optical hardware coming from the TIP work.  And visa versa, the TIP project can leverage the open source work coming out of ODTN on TIP white box hardware building blocks (such as Voyager).

“It is one of the most innovative technical challenges to deploy open SDN / Disaggregation technologies into transport networks. We expect that it will dramatically shorten the service development term and reduce costs,” said Dai Kashiwa, Director of NTT Communications and an ONF board member representative of the NTT Group. “The reference design and implementation for ODTN will accelerate this challenge, and provide common usefulness among many service providers. So, we are so excited that many service providers and vendors have aligned with the ODTN concept, and started collaboration on specifying common requirements and test/deployment plans. We aim to build and nurture an ecosystem that allows us to deploy and operate ODTN-based production networks.”

Leading operators expand ONF mission to create Reference Designs as Gold Standards

AT&T, China Unicom, Comcast, Google, Deutsche Telekom, NTT Group, Telefonica, and Turk Telekom have agreed to back a new strategic plan for the Open Networking Foundation (ONF) focused on developing reference designs for open source, next-generation SDN solutions.

The operators will work together inside the ONF to create Reference Designs (RDs) to serve as “gold standards” for combining component projects into common platforms upon which operators will build solutions.  Each RD will be championed by a select group of operators, and will be designed with participation by invited supply chain partners sharing the vision and demonstrating active investment in building open source solutions.

The work activity will span all network layers, including mobile infrastructure, the edge cloud, multiaccess edge, and optical transport. The ONF has assembled partnerships with OEMs, systems integrators, VNF vendors, platform software developers, next-gen ODMs and chip companies.

The ONF, which was founded in 2011 and is based in Menlo Park, California, has been behind leading open source projects such as ONOS, Trellis and CORD. These projects have gained significant traction with operators as eighteen tier-1 operators are actively testing and trialling these solution. At least two tier-1 operators are moving into production with projects in 2018.

“The ONF is pleased to share our new 2018 strategic plan for market transformation,” said Andre Fuetsch, President and Chair of the ONF Board, and Chief Technology Officer and President, AT&T Labs. “This plan will position ONF as a premier, operator-driven community and will better align and accelerate open systems solutions to the marketplace. The plan is highlighted by two major components: 1) operators and ONF will work together to create common modular reference designs using components such as white boxes and open source platforms, and 2) operators and ONF will work on driving the components of the reference designs to be production-ready, and in selected areas will create integrated implementations of the designs.”

“Operators’ commitment to take open source solutions into production represents the next big step in realizing the full potential of software-defined, disaggregation and open source. It is also heartening to see operators’ determination to enable a new supply-chain that is well aligned with their goals. Clearly this is a landmark moment and it will set our industry on a new course for years to come. I am delighted that operators consider the ONF their partner in pursuit of this important agenda,” said Guru Parulkar, Executive Director for the ONF.

AT&T looks to combine XGS-PON with ONAP for virtualized optical access network

AT&T and the Open Networking Foundation (ONF) announced a collaboration to integrate the ONFs' work on multi-gigabit passive optic networks (PON) with the service automation system, ONAP.

The effort will integrate VOLTHA (Virtual Optical Line Termination Hardware Abstraction), the open source software stack powering PON networks, with ONAP.

AT&T said the idea is to develop virtualized and disaggregated network access for PON networks. The integration will build upon AT&T's ongoing field trials of XGS-PON, which is a fixed wavelength symmetrical 10Gbps passive optic network technology. It also builds upon previous GPON and CORD trials.

The current XGS-PON trial is testing multi-gigabit high-speed internet traffic and providing a AT&T DIRECTV NOW video experience to trial participants. To build the network, AT&T used the following open source software.


  • AT&T Open XGS-PON OLT: an OCP Accepted white box OLT
  • ONOS: the ONF SDN controller that hosts virtual OLT control applications
  • vBNG: a virtual broadband network gateway application to manage subscribers
  • VOLTHA (Virtual Optical Line Termination Hardware Abstraction): an ONF software project that provides hardware abstraction and a highly available SDN driver for OLT devices.
  • VOLTHA, the software powering the PON network trials, was developed by an ONF project community and used the latest in DevOps development techniques to enable rapid prototyping and accelerated delivery to the field trial. AT&T's Foundry in Atlanta developed the vBNG software and AT&T provided overall system integration and field operations for the trial.

"Our network is constantly evolving. Collaboration and openness across AT&T, the ONF, and VOLTHA teams will be key to bringing this 10 Gbps broadband network to customers faster," said Igal Elbaz, senior vice president, Wireless Network Architecture and Design, AT&T. "Now that we've proven the viability of open access technology in our trials, we can start the integration with our operations and management automation platform – ONAP."

"AT&T's Access team has been an important collaborator in ONF's mission to provide open source platforms for software defined broadband access and we look forward to building on this collaboration as we integrate with ONAP," said Guru Parulkar, Executive Director, ONF.

AT&T completes software-based XGS-PON field trials

AT&T completed field trials of a 10 Gbps XGS-PON virtualized network using Open Source Access Manager Hardware Abstraction (OSAM-HA) software in Atlanta and Dallas.

OSAM-HA, which was previously known as Virtual Optical Line Termination Hardware Abstraction (VOLTHA), enables a virtualized Broadband Network Gateway (BNG) function to manage subscribers. OSAM is a vendor agnostic operational suite for managing consumer and business broadband access network elements and capabilities; separate from vendor-specific Access Element Management Systems (EMS).

XGS-PON is a fixed wavelength symmetrical 10Gbps passive optic network technology.  During the trials, the XGS-PON system tested multi-gigabit high-speed Internet traffic and provided a seamless AT&T DIRECTV NOW video experience to participants.

One observation from the trial is that AT&T found it possible for GPON and XGS wavelengths to coexist across a single fiber interface.

“Our network is constantly evolving. We’ll continue to execute our software-based network strategy to technologies like 5G, virtualized RAN, and G.FAST over time. Ultimately, instead of deploying islands of technology that have SDN control, we want to orchestrate the entire end-to-end network through ONAP,” said Eddy Barker, assistant vice president, Access Architecture and Design, AT&T.

ONAP stands for Open Network Automation Platform. It’s our virtual access project within the Linux Foundation and will use the first iteration of OSAM-HA technology.

AT&T completes software-based XGS-PON field trials

AT&T completed field trials of a 10 Gbps XGS-PON virtualized network using Open Source Access Manager Hardware Abstraction (OSAM-HA) software in Atlanta and Dallas.

OSAM-HA, which was previously known as Virtual Optical Line Termination Hardware Abstraction (VOLTHA), enables a virtualized Broadband Network Gateway (BNG) function to manage subscribers. OSAM is a vendor agnostic operational suite for managing consumer and business broadband access network elements and capabilities; separate from vendor-specific Access Element Management Systems (EMS).

XGS-PON is a fixed wavelength symmetrical 10Gbps passive optic network technology.  During the trials, the XGS-PON system tested multi-gigabit high-speed Internet traffic and provided a seamless AT&T DIRECTV NOW video experience to participants.

One observation from the trial is that AT&T found it possible for GPON and XGS wavelengths to coexist across a single fiber interface.

“Our network is constantly evolving. We’ll continue to execute our software-based network strategy to technologies like 5G, virtualized RAN, and G.FAST over time. Ultimately, instead of deploying islands of technology that have SDN control, we want to orchestrate the entire end-to-end network through ONAP,” said Eddy Barker, assistant vice president, Access Architecture and Design, AT&T.

MPLS-TP OpenFlow extensions approved

ZTE announced that the 'MPLS-TP OpenFlow Protocol Extensions for SPTN' (ONF TS-029) technical document proposed by China Mobile has become a formal standard of the ONF (Open Networking Foundation) after receiving unanimous approval from the forum's board of directors.

The release of MPLS-TP OpenFlow Protocol Extensions for SPTN is intended to provide a foundation for interworking between devices from heterogeneous vendors, and between devices and controllers. ZTE noted that China Mobile's large-scale deployment of software-defined packet transport network (SPTN) devices provides an example for other operators, while five operators are believed to be planning to implement the standard in the near future.

ZTE stated that packet transport network (PTN) technology features separate forwarding/control and a centralised management architecture, while OpenFlow offers an open protocol that performs programmable control for flow tables on the forwarding plane. In addition, an abstract adaptation layer supporting OpenFlow to encapsulate the existing forwarding functions of PTN is intended to provide an efficient means of enabling PTN devices with open and software-defined features.

Additionally, this design is expected to facilitate the commercialisation of PTN devices supporting SDN and thereby accelerate the development of the SPTN supply chain.

It was noted that China Mobile has a longstanding commitment to SPTN technology, in mid-2015, working with ZTE, Broadcom and Microsemi, establishing a discussion group within the ONF to research device specifications for SPTN based on OpenFlow and table type pattern (TTP).

In November 2015, a first ONF draft was proposed based on SPTN TTP that extended flow tables, group tables and related fields supporting MPLS-TP, expanded the OF-Config protocol to support QOS, OAM, protection and alarm performance configuration, and leveraged local OAM processing units to ensure a 50 ms protection switching time.

In tandem with the draft specification, China Mobile also organised lab tests for SPTN devices complying with the specifications and amended the document in accordance with the test results. The draft document was subsequently passed for review by experts from a number of ONF technical groups and adopted as a formal standard.

ZTE stated that MPLS-TP OpenFlow Protocol Extensions for SPTN standard is supported by the SPTN industrial supply chain, including chip manufacturers Broadcom, Microsemi, Centec and Marvell, equipment providers ZTE, Ericsson, Fiberhome, Raisecom, Greenwell, Chuling and Huahuan, instrument manufacturer Spirent and open source software Open Daylight and ONOS.

To date it is estimated that more than 50 operators have deployed MPLS-TP-based PTN devices at scale, including China Mobile, which purchased around 590,000 group customer devices compliant with the SPTN TTP standard in 2016. In addition, six equipment vendors have worked with China Mobile to deploy the networks.

OIF Completes SDN Transport Application Programming Interface (T-API) Testing

The Optical Internetworking Forum (OIF) conducted a six-week long global testing of the Transport Application Programming Interface (T-API) standard from the Open Networking Foundation (ONF) with intra-lab and inter-lab testing across five carrier labs: China Telecom, China Unicom, SK Telecom, Telefonica and Verizon.

“As operators move from SDN PoCs and lab trials into commercial deployments, lack of interoperability between the SDN controllers and the orchestration layer above has quickly become the biggest technical barrier for many operators,” said Sterling Perrin, principal analyst, Heavy Reading. “Building a standardized northbound interface and successfully testing interoperability across different vendors and different networks – as the OIF has demonstrated – is a major step forward in addressing the northbound interface challenge and bringing SDN architectures to wide-scale commercial use.”

Thes testing included multi-domain orchestration of services delivered through Ethernet, OTN and optical switching. Carriers and vendors demonstrated how Virtual Network Functions (VNF) and SDN configured connectivity are combined to deliver service life cycle management.

Participating vendors include ADVA Optical Networking, Ciena, Coriant, Huawei Technologies Co., Ltd., Infinera, Juniper Networks, NEC Corporation, Sedona Systems, and SM Optics. Consulting carriers include Orange and TELUS. Academic and/or research institution participants include China Academy of Telecommunication Research (CATR) and Centre Tecnològic de Telecomunicacions de Catalunya (CTTC).

Participants also submitted a proof of concept demo proposal to ETSI NFV called “Mapping ETSI-NFV onto Multi-Vendor, Multi-Domain Transport SDN”.

A technical white paper on the demonstration is available to download.

ONOS Project and ONF Develop Leaf-Spine Fabric

The ONOS Project, which is the open source SDN Network Operating System (ONOS) for service providers and mission-critical networks and hosted by the Linux Foundation, and the Open Networking Foundation (ONF) have collaborated to develop a leaf-spine fabric solution for data centers and service provider Central Offices.

The effort has resulted in the first L2/L3 leaf-spine fabric on bare-metal switching hardware that is built with SDN principles and open source software.

“Underlay and overlay fabrics represent important ONOS use cases,” said Guru Parulkar, executive director of ON.Lab. “ONOS Project, in partnership with ONF and several active ONOS collaborators, have delivered a highly flexible, economical and scalable solution as software defined data centers gain momentum. This is also a great example of collaboration between ONF and ON.Lab to create open source solutions for the industry.”

“This is an L2/L3 SDN fabric with state-of-the-art white box hardware and completely open source switch, controller and application software,” said Saurav Das, principal architect at the Open Networking Foundation. “No traditional networking protocols found in commercial solutions are used inside the fabric, which instead uses an integrated SDN-based solution. In the past, the promise of SDN has fallen short in delivering HA, scale and performance. The fabric control application design, together with ONOS, and the full use of modern merchant silicon ASICs solve all of these problems. In addition, the use of SDN affords a high degree of customizability for rapidly introducing newer features in the fabric. CORD’s usage of the fabric is an excellent example of such customization.”

Some highlights:

  • The fabric is built on Edgecore bare-metal hardware from the Open Compute Project (OCP) and switch software, including OCP’s Open Network Linux and Broadcom’s OpenFlow Data Plane Abstraction (OF-DPA) API. 
  • It leverages earlier work from ONF’s Atrium and SPRING-OPEN projects that implemented segment-routed networks using SDN.
  • It offers HA and scale support with multi-instance ONOS controller cluster (previous work was with single-controller)
  • vRouter for interfacing with traditional networks using BGP and/or OSPF
  • CORD’s vOLT for residential access network support
  • Support for IPv4 Multicast forwarding for residential IPTV streams in CORD
  • Integration with CORD’s XOS-based orchestration framework
