Radisys Shows Multi-Access CORD and Extensible RAN

Radisys will be showcasing the first Multi-Access Central Office Re-architected as a Datacenter (Multi-Access CORD) proof-of-concept and an Extensible RAN (xRAN) PoC at this week's MWC Americas in San Francisco.

CORD is an open architecture platform that leverages data center efficiencies for the delivery of mobile, residential and enterprise services. The initiative was initially developed by ON.Lab as a use case for the ONOS open source SDN operating system, and is now managed as an independent open source project under The Linux Foundation.

Radisys said its two new use cases, both running on its DCEngine open hardware, enable Communications Service Providers (CSPs) to optimize resources in a CORD environment, allowing for rapid roll-out of new services with a better return on investment. Radisys’ Multi-Access CORD use case demonstration proves that since the flexible CORD architecture is agnostic to the access technologies, CSPs can leverage the same CORD data center for both wireline and wireless access. CSPs can thereby deliver a higher quality experience to their subscribers with one open architecture, while reducing network complexity and costs. Radisys’ xRAN use case demonstration allows CSPs to optimize scarce over-the-air resources leveraging real-time data analytics of network conditions. This software-based approach to RAN reduces complexity, OpEx and CapEx, while allowing CSPs to respond real-time to user needs and rapidly roll-out new services.

“The CORD reference architecture meets CSP requirements for next-gen service delivery, while at the same time freeing them from vendor-locked solutions,” said Bryan Sadowski, vice president, FlowEngine and DCEngine, Radisys. “Radisys, in collaboration with the ONF, is making the CORD architecture accessible to CSPs for deployment with these innovative proof-of-concepts as the first step toward Central Office transformation.”

AT&T to launch software-based 10G XGS-PON trial

AT&T announced it will conduct a 10 Gbit/s XGS-PON field trial in late 2017 as it progresses with plans to virtualise access functions within the last mile network.

The next-generation PON trial is designed to deliver multi-gigabit Internet speeds to consumer and business customers, and to enable all services, including 5G wireless infrastructure, to be converged onto a single network.

AT&T noted that XGS-PON is a fixed wavelength symmetrical 10 Gbit/s passive optic network technology that can coexist with the current GPON technology. The technology can provide 4x the downstream bandwidth of the existing system, and is as cost-effective to deploy as GPON. As part of its network virtualisation initiative, AT&T plans to place some XGS-PON in the cloud with software leveraging open hardware and software designs to speed development.
AT&T has worked with ON.Lab to develop and test ONOS (Open Network Operating System) and VOLTHA (Virtual Optical Line Terminator Hardware Abstraction) software. This technology allows the lower level details of the silicon to be hidden. AT&T stated that it has also submitted a number of open white box XGS OLT designs to the Open Compute Project (OCP) and is currently working with the project to gain approval for the solutions.

The company noted that interoperability is a key element of its Open Access strategy, and prompted the creation of an OpenOMCI specification, which provides an interoperable interface between the OLT and the home devices. This specification, which forms a key part of software-defined network (SDN) and network function virtualisation (NFV), has been distributed to standards and open source communities.



  • AT&T joined OCP in January 2016 to support its network transformation program. Earlier this year at the OCP Summit Edgecore Networks, a provider of open networking solutions and a subsidiary of Accton Technology, announced design contributions to OCP including a 25 Gigabit Ethernet top-of-rack switch and high-density 100 Gigabit Ethernet spine switch. The company also showcased new open hardware platforms.
  • At the summit, Edgecore displayed a disaggregated virtual OLT for PON deployment at up to 10 Gbit/ based on the AT&T Open XGS-PON 1 RU OLT specification that was contributed to the OCP Telco working group.
  • Edgecore's ASFvOLT16 disaggregated virtual OLT is based on the AT&T Open XGS-PON 1 RU OLT specification and features Broadcom StrataDNX switch and PON MAC SOC silicon, offering 16 ports of XGS-PON or NG-PON2, with 4 x QSFP28 ports and designed for next generation PON deployments and R-CORD telecom infrastructure.

Cavium and China Unicom trial 5G user cases on M-CORD

Cavium, a provider of semiconductor products for enterprise, data centre, wired and wireless networking, and China Unicom announced a targeted program for the testing of 5G use cases on a M-CORD SDN/NFV platform leveraging Cavium's silicon-based white box hardware in M-CORD racks populated with ThunderX ARM-based data centre COTS servers and XPliant programmable SDN Ethernet-based white box switches.

Under the program, China Unicom and Cavium plan to shortly commence trials in a number of locations across mainland China to explore the potential of the new service.

Cavium and China Unicom are specifically demonstrating multi-access edge computing (MEC) use cases developed through a previously announced collaboration based on the ON.Lab M-CORD (Mobile Central Office Re-architected as a data centre) SDN/NFV platform at the Mobile World Congress (MWC) Shanghai.

The demonstration involves a M-CORD SDN/NFV software platform and hardware rack integrated with virtualised and disaggregated mobile infrastructure elements from the edge of the RAN to distributed mobile core and the ONOS and XOS SDN and orchestration software.

The companies stated that this architecture is designed to enable turnkey operation in any central office or edge data centre for a full NFV C-RAN deployment. The solution is based on a Cavium-powered rack that combines the ThunderX ARM based data centre servers with the programmable XPliant Ethernet leaf and spine SDN switches to provide a full platform for M-CORD.

Regarding the latest project, Raj Singh, VP and GM of the network and communication group at Cavium, said, "Cavium is collaborating with China Unicom to explore 5G target use cases leveraging the M-CORD SDN/NFV platform and working towards field deployment… a homogenous hardware architecture optimised for NFV and 5G is a pre-requisite for field deployments".



  • Earlier this year, Radisys and China Unicom announced they had partnered to build and integrate M-CORD development PODs featuring open source software. For the project Radisys, acting as systems integrator, used the CORD open reference implementation to enable cloud agility and improved economics in China Unicom's network. The companies also planned to develop deployment scenarios for the solution in the China Unicom network.
  • The resulting platform was intended to support future 5G services by enabling mobile edge services, virtualised RAN and virtualised EPC. The companies also planned to develop an open reference implementations of a virtualised RAN and next-generation mobile core architecture.

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.

The New Open Source Networking Universe, managed by The Linux Foundation

This month's Open Networking Summit (ONS 2017) in Silicon Valley, which marked the sixth instalment of the annual event since its origin at Stanford University, once again brought many key thought leaders together for keynotes, tutorials, conference sessions, panel discussions and a small exhibition. ONS was the event that set off alarm bells across the industry in 2012 when Google announced that SDN had moved well beyond the research phase and into its commercial network, using a home-grown solution and no routing equipment from conventional vendors.

As far as the current state of open source networking is concerned, perhaps Margaret Chiosi, formerly at AT&T and now with Huawei, put it best, commenting (paraphrased from her keynote), 'open networking has reached the peak of exuberance and not yet crossed the chasm of despair'. In other words, great ideas are flourishing but no one is yet really making money or saving money with open networking. In addition, Guru Parulkar, executive director of ON.Lab, observed that while there are many proof-of-concepts and early deployments, a 'resource gap' of qualified professionals may delay large scale deployments. New technology is difficult and committed resources must be in place if network transformations are to really happen.

ONS 2017 was presented by The Linux Foundation, the San Francisco-based organisation with the lofty ambition of creating the 'largest shared technology investment' in history. A mural at the entrance to the exhibition depicts the New Open Source Networking Universe, and certainly a tremendous amount of intellectual capital is being collected, curated and assembled into specifications and frameworks impacting every layer of the network.

The following is the line-up of networking related projects underway at the Linux Foundation (although there are more non-networking LF projects and other open source networking projects, such as Open Stack, that are not managed by LF).

ONAP

The Open Network Automation Platform (ONAP) unites two major open networking and orchestration projects, AT&T's open source ECOMP and the Open Orchestrator Project (OPEN-O). This newly launched LF project is one of the largest open source networking initiatives, with members including Amdocs, AT&T, Bell Canada, China Mobile, China Telecom, Cisco, Ericsson, GigaSpaces, Huawei, IBM, Intel, Metaswitch, Nokia, Orange, Tech Mahindra, Reliance Jio, VMware, ZTE and other leading network operators, OEMs and platform providers.

OPNFV

A carrier-grade, integrated, open source platform to accelerate the introduction of new NFV products and services. OPNFV is mainly focused on building NFV Infrastructure (NFVI) and Virtualized Infrastructure Management (VIM) by integrating components from upstream projects such as OpenDaylight, OpenStack, Ceph Storage, KVM, Open vSwitch and Linux. At ONS 2017, OPNFV made its 4th major release, codenamed Danube, adding foundational support for MANO. The next release, codenamed Euphrates and targeted for completion by October, is expected to include more containerisation support.

Open Daylight

One of the largest projects, this promotes and advances the global development, distribution, and adoption of the OpenDaylight (ODL), the largest open source SDN controller. Many industry vendors participate in ODL.

ONOS

A SDN operating system for service providers that has scalability, high availability, high performance and abstractions to make it easy to create applications and services. At ONS 2017 the ONOS community made its next platform release, adding support for IPv6 routing, vLAN tagged external interfaces and AAA endpoint authentication, a better GUI interface, VPLS support and various southbound enhancements. Notable members of the ONOS community include AT&T, Comcast, China Unicom, Google, NTT Communications, SK Telecom and Verizon.

CORD

Central Office Re-architected as a Data Center (CORD) combines NFV, SDN and the elasticity of commodity clouds to bring data centre economics and cloud agility to the telco central office (CO). CORD lets the operator manage central offices using declarative modelling languages for agile, real-time configuration of new customer services. Three versions are underway - Mobile CORD, Residential CORD, Enterprise CORD – and each has multiple proof-of-concept demos.

DPDK

The Data Plane Development Kit (DPDK) consists of libraries to accelerate packet processing workloads running on a wide variety of CPU architectures. DPDK was created in 2010 by Intel and made available under a permissive open source license. Today, more than 20 key open source projects build on DPDK libraries, including MoonGen, mTCP, Ostinato, Lagopus, Fast Data (FD.io), Open vSwitch, OPNFV, and OpenStack. This community has just moved to the Linux Foundation. Gold members of the project are ARM, AT&T, Cavium, Intel, Mellanox, NXP, Red Hat, and ZTE; Silver members include 6WIND, Atomic Rules, Huawei, Spirent, and Wind River. The Korea Advanced Institute of Science and Technology (KAIST), University of Limerick, University of Massachusetts Lowell and Tsinghua University are Associate members.

FRRouting (FRR)

Free range routing (FRR) is a project endeavouring to make the best open source routing stack. FRR, which originated in the Quagga project, includes protocol daemons for BGP, IS-IS, LDP, OSPF, PIM and RIP. At ONS, it was announced that this project will now be managed by the Linux Foundation.

Open Switch (OVS)

An open-source implementation of a distributed virtual multi-layer switch, the main purpose of Open vSwitch is to provide a switching stack for hardware virtualisation in a network.

PNDA

Platform for Network Data Analytics (PNDA) aims to eliminate complexity by integrating, scaling and managing a set of open data processing technologies and by providing an end-to- end platform for deploying analytics applications and services. The big idea is that open source big data analytics can play in accelerating the transition to more agile, assured and orchestrated services. At ONS 2017, the MEF demonstrated a reference implementation of LSO (Lifecycle Services Orchestration) analytics using PNDA.

AllJoyn

AllJoyn is developing an open source framework for IoT.

Cloud Foundry

Cloud Foundry aims to make it faster and easier to build, test, deploy and scale applications.

The Cloud Native Computing Foundation

This group focuses on the development of open source technologies, reference architectures and common formats for cloud-native applications or services.

The Open Container Initiative

Building a vendor-neutral, portable and open specification and runtime for container-based solutions, founding members of this initiative include nine new companies committed to the OCI, with members including: Amazon Web Services, Apcera, Apprenda, AT&T, ClusterHQ, Cisco, CoreOS, Datera, Dell, Docker, EMC, Fujitsu Limited, Goldman Sachs, Google, Hewlett Packard Enterprise, Huawei, IBM, Infoblox, Intel, Joyent, Kismatic, Kyup, Mesosphere, Microsoft, Midokura, Nutanix, Odin, Oracle, Pivotal, Polyverse, Portworx, Rancher Labs, Red Hat, Resin.io, Scalock, Sysdig, SUSE, Twistlock, Twitter, Univa, Verizon Labs, VMware and Weaveworks.

The Xen Project


This is the leading open source virtualisation platform that powers some of the largest clouds in production today. Amazon Web Services, Aliyun, Rackspace Public Cloud, Verizon Cloud, and many hosting services use Xen Project software.

The Open Network Automation Platform looks like a turning point for telecom architecture

The biggest news out of the recentOpen Networking Summit in Silicon Valley is that the Open Network Automation Platform (ONAP) Project, which unites AT&T's open source ECOMP and the Open Orchestrator Project (OPEN-O), has made substantive progress toward becoming a dominant lifecycle service management platform for the telecom industry.

Senior executives from AT&T, China Mobile and The Linux Foundation took the ONS stage to declare that ONAP is not only a path towards more open, agile and cost effect carrier networks, but it is perhaps The Path forward for the networks that support the majority of the world’s mobile users. Besides AT&T (with 135 million mobile users) and China Mobile (853 million), the ONAP project has attracted the endorsement, support or commitment to early trials from other key operators including Orange (265 million accesses), Bell, China Telecom, China Unicom and the hot, new Reliance Jio in India. Together, these operators serve 38% of the global wireless subscriber base. The Linux Foundation said they are already in discussions with mobile operators representing a further 34% of the global subscriber base, so clearly we are talking about enormous market clout.

The project description for ONAP states that ONAP is an open source software platform that delivers capabilities for the design, creation, orchestration, monitoring and life cycle management of: low-level virtual network functions (VNFs); the carrier-scale software defined networks (SDNs) that contain them; and higher-level services that combine the above.

From a functionality point of view, ONAP is expected to handle:

•   Automated onboarding.

•   Automated deployment.

•   Automated management.

•   Intelligent operation of network resources using big data and AI for policy optimisation.

The first vendors to announce ONAP support include companies that worked with AT&T on its ECOMP and Domain 2.0 initiatives, including Amdocs, Cisco, Ericsson and Metaswitch, along with key suppliers for the OPEN-O project, which include Huawei, H3C and ZTE). However, with this level of market momentum, expect all vendors to jump on board as quickly as possible. As the ONAP technical steering committees get establish, now would seem a good time to demonstrate enthusiasm and expertise in this new project.

A developer Wiki has already been set-up (and can be accessed here: https://wiki.onap.org/), and the ONAP governing board members have elected the individuals to serve in key roles, while the governance structure was established via The Linux Foundation, with key appointments including:

•   Chair: Chris Rice, SVP of AT&T Labs.

•   President: Yachen Wang, deputy director of the Network Technology Department at China Mobile Research Institute.

•   Treasurer: Vincent Danno, director wireline standards, Innovation Technical and Marketing at Orange corporate.

How we got here

AT&T’s Enhanced Control, Orchestration, Management and Policy (ECOMP) platform has been running in its production network for the past two and half years. The company states that ECOMP contains over 8 million lines of code and that over one hundred virtual network functions are currently supported, including all of its VoLTE traffic. The ECOMP capabilities are also multi-layer, with optical wavelengths orchestrated by the system.

ECOMP was first publicly discussed in depth by AT&T at ONS 2016 (March 2016), when John Donovan, the company’s chief strategy office, described it as the 'next big thing'. Donovan said ECOMP was the most sophisticated software project that AT&T has ever undertaken. ECOMP's aim was to be the engine that powers its software-centric network, with the goal of enabling high utilisation of network resources by combining dynamic, policy-enforced functions for component and workload shaping, placement, execution and administration. At the time, AT&T published its ECOMP white paper, which has since attracted over 7,000 downloads.

In September 2016, Orange became the first telecom company to join AT&T's ECOMP effort. Orange agreed to test the platform for creating and managing its own software-defined network. The carriers also agreed to collaborate on open source and standardisation initiatives to accelerate the standardisation of SDN and NFV. As the first ECOMP partner, Orange perhaps played a critical role in persuading AT&T to move ahead with the idea of contributing its 8 million lines of code to open source. After all, there must have been many reasonable voices from within the company advising against a new and risky strategy of giving away its intellectual property, its crown jewels, for free. In December 2016, Bell Canada became the second carrier to join the ECOMP team.

The OPEN-Orchestrator Project (OPEN-O) was first announced at Mobile World Congress 2016. Its mission was to develop the first open source software framework and orchestrator to enable agile software-defined networking (SDN) and network function virtualisation (NFV) operations. The initiative was driven by China Mobile and Huawei, with early support from Brocade, China Telecom, DynaTrace, Ericsson, F5 Networks, GigaSpaces, Infoblox, Intel, KT, Red Hat, Raisecom, Riverbed and ZTE. In November 2016, OPEN-O launched its first major software release, codenamed SUN.

Many questions about what comes next

With the agreement only just coming into place and technical integration work yet to begin, it is too early to forecast how other models will be impacted. Is it game over for other service orchestration systems? Will other open networking projects, such as ONOS, Open Daylight and OPNFV be redirected to become perfect fits into ONAP? How will ETSI NFV evolve? And what of privately-developed orchestration systems, such as BluePlanet?

Presumably these will also need to adapt to the coming reality of a widely supported ONAP. On the other hand, will one open orchestration system be able to fit all use cases and service providers? And what about the public cloud providers?

The telcos are racing to make their infrastructure hardware more like cloud data centres, while companies such as AWS already have sophisticated software systems in place to bring up new equipment, services and customers quickly and efficiently. From the cloud operators perspective, will the 8 million lines of ONAP prove to be impressive? If so, and if the majority of telcos really agree to this common service orchestration model, will this give them an advantage over cloud operators?


Microsoft has already joined the ONAP project, the only cloud provider to announce its membership in the group so far. However, it is possible that a cloud provider like Google or Microsoft could have a better orchestration system, and perhaps they could find a business case to offer it on a wholesale basis.

Calix unveils AXOS OFx OpenFlow Connector for ONOS/CORD

Calix of Petaluma, California, a provider of Subscriber Driven Intelligent Access solutions, has announced the completion of the AXOS OFx (OpenFlow) Connector for the ON.Lab vOLT-HA (virtual optical line terminal-hardware abstraction) open source project.

Leveraging the native NetConf/Yang interfaces of the Calix AXOS platform, OFx si designed to enable the rapid integration of the AXOS Software Defined Access platform into ON.Lab ONOS and CORD (Central Office Re-imaged as a Datacenter) networks.

Calix stated that AXOS OFx, which was implemented in under four weeks, represents the start of the anySDN era, and marks the first time that CORD has been extended to commercial OLT systems, thereby allowing service providers to advance with the plug-and-play adoption of CORD for production networks.

The new AXOS OFx Connector is the next step in Calix's ongoing involvement with the ON.Lab ONOS and CORD projects. The company noted that as service providers begin to implement a CORD architecture, OFx Connector and the vOLT-HA software will provide the integration layer and enable operators to integrate OSS and SDN controllers into their business systems.

In addition, the OFx and vOLT-HA solutions will allow new products such as Calix's AXOS E9-2 intelligent edge system to be quickly installed into the network without the need for integration work.

Calix noted that service providers seeking to leverage its anySDN technology offering can download AXOS Sandbox to enable integration and testing of production software releases of Calix systems virtually, without the need for Calix hardware.


AXOS Sandbox offers a virtualised AXOS system software implementation that complements the AXOS architecture and is designed to allow OSS/BSS integration in a risk-free environment. AXOS Sandbox provides virtual instances of production Calix system software, allowing partners to create a virtual network for testing of broadband services. As well as the management plane of AXOS systems, AXOS Sandbox also provides the data plane and control plane elements.

Israel's Neptune Consortium Demos vCPE

Neptune, the Israeli consortium for network programming, announced that it has performed a general demonstration of its technologies as part of its mission to build on the software defined networking (SDN) and network functions virtualisation (NFV) technologies that are currently under development.

Neptune is seeking to significantly reduce the time required to deploy new services and new service types, enable more efficient use of network and computational resources, and facilitate faster and more intelligent response to network events.

The latest demonstration by Neptune included four industry firsts, as follows:

1. A multi-vendor vCPE demonstration, in which a single service provider OpenStack controller established end-to-end services terminating on virtual CPE (vCPE) from three vendors, ADVA, Telco Systems and RAD, all running on top of a Mellanox switch and HCA adaptor.

2. Satellite network vendor Gilat demonstrated vCPE capabilities in a satellite ground segment gateway, including integration of tactical mobile ad-hoc network (MANET) UHF radio networks into an SDN and NFV-based multi-vendor heterogeneous virtual RAN (vRAN) based on technology developed by Elbit Systems Land and C4i.

3. The above demonstration also featured Open Mobile Edge Cloud (OMEC) with the first fully virtual cellular base station (from modem to management) developed by ASOCS and accelerated by a pool of network attached programmable hardware accelerators.

4.Transport of the common public radio interface (CPRI) standard over microwave by Ceragon Networks.

In addition, ECI Telecom demonstrated how its multi-layer service app is able to perform fast recovery from optical-layer faults employing an ONOS controller combined with OpenFlow optical extensions, and ADVA presented MEC for the delivery of enterprise services.

The demonstration was conducted at a Bezeq International facility, supported by equipment located at four other sites, and attended by outgoing chief scientist of the Israel Ministry of Economy and Industry, Avi Hasson, the head of the chief scientist's technological infrastructure division, Ilan Peled, Neptune chair Dr. Yaakov Stein, and representatives of the consortium members.

Neptune was founded in 2014 to develop methods to automate and programmatically manage service provider networks, irrespective of underlying network technologies leveraging SDN and NFV. Backed by the Israel Innovations Authority (formerly the Office of the Chief Scientist of the Ministry of Economy and Industry), consortium members include: ADVA (Israel), ASOCS, Bezeq International, Ceragon Networks, ECI Telecom, Elbit Systems, Gilat Satellite Networks, Mellanox Technologies, RAD and Telco Systems (BATM Group).

CORD and xRAN Consortium Partner in Software-based Extensible RAN

CORD and xRAN consortium partner to develop carrier grade software-based, extensible RAN February 23rd The CORD Project, an open source project seeking reinvent network access via enabling data centre economics and cloud agility in the central office, announces an agreement to partner with xRAN Foundation to collaborate on standardising and promoting a software-based, extensible RAN (xRAN) architecture.

The partnership is intended to deliver a carrier grade, open reference implementation of xRAN specifications within M-CORD for a next generation RAN architecture. Designed to address the challenges associated with closed, proprietary RAN systems and the future demands of 5G, the CORD Project and xRAN are combining two ecosystems of service providers, vendor and open source communities.

Through the initiative, the xRAN consortium will focus on developing software-defined standards for the architecture and interface definitions for next-generation RAN; the CORD community will focus on implementing xRAN standard APIs, a RAN controller based on ONOS and example RAN control applications for the M-CORD platform leveraging both open and closed hardware from multiple vendors.

As part of the partnership, ON.Lab has announced the appointment of Dr. Sachin Katti, Professor of EE and CS at Stanford University, as chief scientist for mobility to guide the integration of xRAN with M-CORD.

The collaboration is expected to establish a symbiotic relationship between standards and API specifications and reference implementations, and thereby allow the use of specifications to help improve the reference implementation, while experience with the reference implementation can help improve specifications. In addition, extended engagement with the open networking ecosystem will help to create software- defined standards and a reference implementation, and help speed the adoption of software defined RANs.

Founded in October 2016, the xRAN consortium has developed standardised RAN control interfaces that allow carrier applications to programmatically control multi-vendor RAN infrastructure and have been adopted by carriers. xRAN aims to decouple the RAN control plane from the user plane, build a modular eNB software stack that operates on COTS hardware and release open north- and south-bound interfaces.

Members of the xRAN consortium include AT&T, Deutsche Telekom and SK Telecom, plus Intel, Texas Instruments, Aricent, Radisys and Stanford University.

Regarding the partnership, Andre Fuetsch, president of AT&T Labs and CTO, commented, "AT&T has been a founding member and active supporter of both xRAN and CORD, and the time is right for xRAN and M-CORD to come together… the xRAN and M-CORD partnership will allow the building of mobile access networks with the ability to customise and optimise the RAN and to more quickly create new services…".
