Leadership Team Update

Craig Thomas, BBF Director of Strategic Marketing

Just a week before we came together for the Q4 meeting in Kona, Hawaii, the Mauna Loa volcano erupted for the first time in nearly four decades. The last time an eruption occurred was in 1984. Back then, only eight percent of households owned a computer and 99 percent of the US population was not connected to the Internet. Fast forward to 2022 and the development of open standards and the enablement of smarter and faster broadband networks has changed the face of the earth.

Despite the natural disaster on our doorstep and with Hawaii being one of the most isolated places on Earth (nearly 2,500 miles from mainland US) our members still gathered for the final meeting of the year.

This last quarter has seen our members continue to educate and inform the sector through our industry events. We had our successful CloudCO Demo (available to watch here on demand) at Network X with 14 vendors, service providers, and consultancy companies coming together to demonstrate greater automation, reduced network congestion and greater interoperability. Our BASe North America event also attracted a lot of attention and built awareness of our important work.

For those interested in getting involved, our global BASe 2023 sponsorship is now open. So, please get in touch. Our total membership reached a 10-year high, with 19 new members during 2022. We always appreciate new member referrals and have a referral award process if you know any other potential members that would like to join.

It has been a busy quarter for external communications with 14 press releases, blogs and editorial features going live. This has spanned a range of Work Areas including disaggregated access nodes, QED, 5G Transport, WWC, G.hn Access Pre-Certification Plugfest, the CloudCO demo and the app-enabled services gateway.

A big congratulations to our new Work Area Directors that will embark on two-year terms from 2023! Moving forward, our annual meeting is moving to Q2, and our Board of Directors election will also be completed during the second quarter with the nomination deadline moving to April instead of January.

We have announced our dates for next year’s quarterly meetings with the first is in Dallas/Fort Worth on March 20-23, 2023, and the following three set to be in Europe (Q2), Virtual (Q3), and Asia (Q4). We look forward to seeing you next year! Thanks for your efforts during 2022.

Astronomy meets broadband

Marc Kassis, Instrument Program Manager at the W. M. Keck Observatory joined us in Hawaii and provided an overview of the observatory that has produced Nobel Prize winning science and has led the astronomical world in discoveries for three decades. Current instrumentation activities were also outlined and this included the installation and commissioning of our newest instrument, the Keck Planet Finder, that achieved first light a month ago.

Marc advised how collaboration with Hawaii’s mainland instrument developers and science community helps identify and bring to life new technologies. Broadband plays a critical role in this instrumentation and observing, and these new technologies help keep the observatory at the forefront of astronomy.

Watch Now! Broadband Forum’s CloudCO Demo 2022

This year’s CloudCO demo, showcased at this year’s Network X, was a great success! We had more than 25 demonstrations during the three days with high operator interest, and significant new vendor interest wanting to get involved in the 2023 demo.

With the increasing adoption of software defined access networks, the separation of control and data planes is driving an increasing need for the virtualization and disaggregation of operator’s networks and functions.

Visit Broadband Forum’s YouTube channel as we hear from Lincoln Lavoie, Technical Committee Chair at Broadband Forum and Ken Ko, Managing Director at Broadband Forum as they discuss this year’s CloudCO demonstration.

The industry’s appetite for informative and educational demos are increasing and we have already identified three initial 2023 demo candidates, including CloudCO, USP including the app-enabled services gateway and the first working demo of WWC’s Phase 2 and Phase 3 work.

Watch this year’s CloudCO demo here.

Improved network performance measurement and analysis enabled by Broadband Forum

The Broadband Forum logoBroadband network operators can now take advantage of improved performance measurement and analysis tools with the principles of quality attenuation being applied more widely to operators’ networks and at low cost by leveraging its capabilities in pre-existing equipment – for example, in CPE devices.

Crucially, the TR-452.2 extension to Broadband Forum’s Quality Attenuation (QED) framework means that real-world quality attenuation testing such as proactive analysis of network performance and support for customer service troubleshooting can now be done, taking testing beyond network design and lab evaluation. This will help operators identify and resolve network faults before customers perceive any service issue, as well as enable the arrangement and delivery of new experience-specific Service Level Agreements (SLAs).

“In an evolving broadband market, once broadband speed stops constraining service delivery, Quality Attenuation (which includes latency, jitter and packet loss) becomes the most important metric to delivering QoE for increasingly time-sensitive applications,” said Craig Thomas, Vice President Strategic Marketing and Business Development at Broadband Forum. “A standards-driven approach is critical to how metrics are automated and continuously measured leading to zero-touch Automated Intelligent Management (AIM) tools that ensure subscriber service quality.”

The Quality Attenuation (QED) framework is developed by the Broadband Quality of Experience Delivered (Broadband QED) initiative from Broadband Forum. It uses Quality Attenuation to encompass factors such as latency, consistency, predictability, and reliability, enabling operators to look beyond conventional measurements, such as Quality of Service (QoS), as a standalone litmus test of quality, and provide deeper insights into QoE and application outcomes.

Editorials went live on Quality of Experience, USP, Multi-Dwelling Unit connectivity, the app-enabled services gateway and embracing open standards

A host of editorial articles went live during the last quarter, covering a range of topics spanning the broadband ecosystem. Broadband Forum Chairman John Blackford spoke to Telecom Tech Outlook about how the app-enabled services gateway is a game-changer for service providers and a great opportunity for the industry to grasp. Achieving Multi-Dwelling Unit connectivity with broadband access extension technologies was a topic discussed by PHYtx Work Area Director Herman Verbueken in Broadband Communities Magazine.

The need for a unified, interoperable, and standardized platform to develop value-add solutions is paramount for the connected home according to Leader of the "BUS Data Modeling" Project Stream at Broadband Forum, Daniel Egger in Telecoms.com. Broadband Forum Technical Chair Lincoln Lavoie spoke to ISE Magazine about how embracing open standards together with open source can help CSPs upgrade and transform their networks.

Speed is no longer enough, and the industry needs to prioritize network quality over bandwidth according to Broadband Forum Vice President of Strategic Marketing and Business Development Craig Thomas in Fibre Systems.

Common YANG never sleeps; new TR-383 Amendment is on the way

Target: Specify YANG modules that are applicable to multiple Work Areas, provide support to those same Work Areas for their specific YANG projects, and maintain YANG Best Current Practices, processes, procedures, and tools.

Progress: Good progress on the functional modeling of nodes supporting MoCA Access 2.5 interfaces.

Outcomes: Completion of Straw Ballot comment resolution of Amendment 6 of TR-383; accepted proposal to define a YANG model for bulk data export via IPFIX.

The Common YANG Work Area continued to make good progress on its key project deliverables, in close collaboration with both SDN/NFV and FAN Work Areas.

Straw Ballot comment resolution on Amendment 6 of TR-383 ‘Common YANG Modules for Access Networks’ was completed, with an overall objective for publication by Q1 2023. This next amendment aims to add functionality that addresses scale in large networks, as well as further improving existing functionality.

A first proposal was reviewed covering the functional modeling of the Multimedia over Coax (MoCA) Head-end and Client Nodes, as part of WT-496 ‘YANG Modules for MoCA Access 2.5 Interface’. It is expected that derived YANG data models will be brought forward in a follow-up interim conference call.

The group accepted a proposal to define a YANG model for the management of bulk data export via IPFIX. This will be added in a future amendment of WT-383. The group will start a review of the associated YANG module specification.

Joint sessions were held with the SDN/NFV and FAN Work Areas to review items of common interest, including proposed changes to Issue 2 WT-413 ‘SDN Management and Control Interfaces for CloudCO Network Functions’, contributions on Issue 2 of WT-386 ‘FANS Access Network Sharing Interfaces’ and work on PON management.

Moving forward, the group will continue the formal review of the specification of YANG modules for VoIP; this topic did not get addressed at the meeting but will be covered during a series of interim conference calls. This work is intended to be covered in a future amendment of TR-383.

SDN/NFV closes in on publication of TR-477 on disaggregated Access Nodes

Target: Define the Cloud-based Central Office (CloudCO) architecture using SDN, NFV, and cloud technologies to support network functions fundamentally redefining the architecture of access and aggregation networks and support the migration of SDN and NFV into all aspects of broadband networks facilitating the agile deployment of new distributed broadband services and applications for operators with greater operational efficiency and lower cost. 

Progress: The SDN/NFV Work Area continues to progress the CloudCO project for virtualized network functions, SDN management and control and domain orchestration capabilities in a broadband network. The main activities currently ongoing are related to the disaggregation of the Access Node and defining the related interfaces. The “Cloud Component” Project Stream is continuing work on Automated Intelligence Management (AIM), Fixed Access Network Sharing and Smart SD-WAN.


WT-477 on Access Node disaggregation is close to be completed. The missing data models were created and reviewed by the Common YANG and FAN Work Areas in a joint session. Further details need to be analyzed to finalize the document.

WT-413 Issue 2 on ‘SDN Management and Control Interfaces for CloudCO Network Functions’ is progressing. In a joint meeting, the SDN/NFV and Common YANG Work Areas reviewed the approach and agreed to report a detailed list of data models, so that vendors can rapidly discover the data models to be implemented for each access network function.

On the Artificial Intelligence and automation fronts, work continues on WT-486, which specifies the interfaces for the previously published AIM Framework specification TR-436. Contributions were submitted on the missing interfaces and now the document is almost ready for Straw Ballot. It was also discussed whether further details are needed for specific implementations and if a liaison needs to be submitted to TM Forum. While this is a different Project Stream within the SDN/NFV Work Area, network automation and closed-loop operations are imperative for simplifying network validation and engineering, streamlining network deployment and upgrades, and improving operations with less error-prone and automated OAM in the CloudCO environment. This will also automate some management functions and help realize rapid troubleshooting and pre-emptive maintenance.

There was a proposal related to an initial set of YANG data models for WT-386i2 on Fixed Access Network Sharing discussed in a joint call with the Common YANG and FAN Work Areas. It was agreed that comments would be received ahead of final approval.

The Work Area has also approved NPIFs for three focus areas. This includes Access Node Disaggregation (WT-477i2) to include new virtualized functions, AIM Framework (WT-436i2) to extend the architecture for new use cases, and on CloudCO interfaces (WT-411i2) to include the Access SDN Management and Control northbound interface intent-based interactions addressing access network topology and abstraction.

Two NPIFs were also proposed on vOMCI Telemetry (WT-451i2) with partially different scopes. It was agreed to merge them together into a single project that also includes possible impact on other documents (e.g. WT-477).

Bjørn Ivar Teigen, Head of Research at Domos discussed the notable advantage of dynamic subscriber session steering in a blog post focused on this year’s CloudCO demo at Network X. The blog highlighted how subscriber session steering can allow an ISP to dynamically re-allocate resources between isolated slices in a running network and increase a subscriber’s bandwidth on-demand.

Bruno Cornaglia and Mengmeng Li, SDN/NFV Work Area Co-Directors at Broadband Forum discussed how disaggregating Access Nodes brings simplified operations and promotes greater competition within the supply chain. The blog post from Bruno and Mengmeng also outlined the business motivations offering greater choice for operators. 

More information about the SDN/NFV Work Area can be found at: SDN and NFV home page.

WWC is finalizing key Phase 3 specifications

Target: Address the needs of operators, which have wireline or mobile networks deployed so they can leverage their assets with combined subscriber offerings with a converged core.

Progress: The WWC Work Area is progressing its work on the third phase of specification development. It currently has two active Project Streams, the 5G Project Stream and IMS for 5G-RG Project Stream. With this work, the group continues to subsume more of the capabilities of the 5G architecture.

Outcomes: Work continues on a new set of capabilities and enhancements with the latest specifications in progress for subsequent publication.

Work in the WWC Work Area has transitioned from improving the basic set of specifications in Phase 2 to focusing on topics that bring more value to 5G for wireline and provide operators with increased flexibility, revenue potential and deployment options. The goal is to increase the service capabilities of the network to allow operators to fully leverage convergence of their networks while at the same time giving them more paths to transition their networks to a single 5G Core.

The group continues to incorporate capabilities from the 5G toolkit into our specifications to realize a variety of use cases. These range across a broad spectrum and include topics such as hybrid access, enhanced work from home, access sharing scenarios and convergence of voice with the mobile system. This work will allow converged operators to provide a uniform experience to their customers irrespective of the access or appliance they are using, supported by a common and streamlined back office and control plane.

The 5G Project Stream is working on finalizing two specifications, WT-457 (FMIF Functional Requirements) and WT-458 (CUPS for 5G Wireless Wireline Convergence), with WT-458 scheduled to enter the Straw Ballot process before the Q1 Meeting, following WT-457 which has undergone Straw Ballot review in the Q4 Meeting. Both of these documents expand the deployment options for 5G WWC. The IMS for 5G-RG Project Stream addresses 5G-RG IMS Voice support, with work on the architecture and a profile for residential voice. Work is moving forward on WT-493 (IMS for 5G-RG Architecture) and WT-494 (IMS for 5G-RG Residential Voice Requirements). This key piece of work will converge legacy voice services onto the 5G system. With these two key baseline texts established, there is now an opportunity for all interested parties to contribute to this important work.

The group along with the BUS Work Area continue to work with 3GPP to introduce the Release 18 Study output, and this is expected to facilitate a WWC study around “Devices behind the RG”. The BUS and WWC Work Area has jointly reviewed and responded to the liaison, according to the ongoing collaboration with 3GPP on WWC and 5G-RG management requirements.

The WWC Work Area has been discussing plans for the group’s first demonstration at an industry event to showcase the 5G Phase 2 and Phase 3 work. The group continues to expose the industry to the latest WWC work and supports the ongoing education and marketing activities, including the continued development of its webinar series.

Broadband Forum is taking an important role in developing 5G, continuing the productive cooperation with 3GPP, and making recommendations for the connection points between the fixed and 5G mobile core networks in order to drive core convergence.

Christele Bouchat and Manuel Paul, Work Area Directors of the Wireless-Wireline Convergence Work Area at Broadband Forum produced a blog post this quarter on achieving a smooth evolution path to a standardized 5G hybrid model. The blog discusses how operators can unlock more value and a greater range of options thanks to Broadband Forum’s latest phase of specifications.

OB-BAA’s Release 5.1.1 launched during fourth quarter

OB-BAA – Ongoing collaboration between Open Source and Open Standards continues to advance and accelerate the adoption of interoperable, standardized solutions across the industry.

The Open Broadband – Broadband Access Abstraction (OB-BAA) project team successfully launched Release 5.1.1 in November. This included enhancements and fixes to the existing OB-BAA software, providing enhancements to microservices discovery and scale testing of 10,000 ONUs. The group also continues to plan Release 6.0 activities, with discussions continuing on identifying a list of candidates to focus on.

For more information on the OB-BAA project’s latest work, see: Open Broadband-Broadband Access Abstraction Project Home

OB-MAP and prpl Foundation continue joint collaboration

The Open Broadband – Multi Access Point (OB-MAP) project and the prpl Foundation’s prplMesh project are establishing a baseline vision of how data and control commands will be represented in TR-181. This will influence the design of the APIs presented by prplMesh. The data model (and prplMesh APIs) will meet the diagnostics and management needs of service providers that use multiple physical layer networking technologies to deliver ever-increasing broadband bandwidth and innovative services through increasingly complex home networks to end-user devices.

The OB-MAP project team has continued to collaborate with the prpl team on requirements and feature prioritization, and data modelling of multiple devices and services in a mesh network. Progress has also been made on prplMesh’s Northbound API (NAPI), and the group has been assisting with the use and definition of Broadband Forum’s USP support for internal services. Recently, work continued on defining management interfaces for:

  • Network-wide SSID, with groupings and an underlying distribution system / VLAN.
  • Statistics and topology for wired stations and wired backhaul
  • IEEE 1905 neighbor statistics
  • Unassociated station statistics
  • Extender with both EasyMesh agent and USP/cloud agent
  • Station statistics while roaming

Goldeneye Release rounds off successful 2022 for OB-USP-Agent

OB-USP-Agent Release 7 (Goldeneye) is wrapping up in the next few weeks. Goldeneye is mostly a maintenance release with the following focus:

  • Key improvements around the MQTT MTP implementation.
  • Performance improvements for large data models that can result in big Get responses.
  • Fixes related to compliance testing and the updated TP-469a2 Test Plan.
  • Resolution of some known issues (including several raised in GitHub).

The plan is to keep to the usual OB-USP-Agent six-month release cadence, which means that the team will be scoping Release 8 at the start of the year with an expected release date of mid-2023. Based on recent OB-USP-Agent meeting discussions and the BUS Work Area’s focus on finalizing the Services Architecture solution, it looks like Release 8 will mostly focus on implementing the UNIX Domain Socket MTP and the associated components. This will help enable USP communications between services within the CPE.

Ninth OB-UDPST Release:  applicability to mobile access measurement improves

Current progress: The project team delivered its Ninth release, 7.5.1 on November 18, 2022. This release incorporates feedback from users of a key enhancement in Release 7.5.0, which was the new “Type C” load adjustment (search) algorithm, which is faster and more dynamic than “Type B”. The 7.5.1 release adds a new feature in response to testing/experience on mobile/radio access with the new algorithm. In this feature, the team made the decision that UDPST will now ignore the Reordering and Duplication impairments as input to the load adjustment search algorithms as the default. Reordered and Duplicate packets are legitimate contributions to IP-Layer Capacity and are sometimes prolific in mobile access environments. The UDPST utility still measures these impairments in every test, so this change only affects the impairment processing in Type B and Type C algorithms.

Issue 3 of TR-471 now incorporates all the 2022 improvements and features implemented by the OB-UDPST project. TR-181 has been updated with changes to the UDPST data model and the default configuration settings. The team also ensures that ITU-T Recommendation Y.1540 and other industry specifications remain in-sync with UDPST running code.

The OB-UDPST project team contributes to the IETF IP Performance Measurement (IPPM) Internet Draft development of the UDPST protocol specification and measurements. This includes evaluation of UDPST-based measurements to assess “Latency under Working Conditions/Load”. Latency is a topic of considerable interest when attempting to support cloud game-players and the platforms they use, in addition to requirements for sufficient IP-Layer Capacity (a metric and measurement already standardized in TR-471 and RFC 9097).

Future Plans: The project team provided its status report to the Open Broadband Oversight Committee (OBOC) in November 2022. The UDPST applicability to Working Latency measurement, and the ability to implement application-layer traffic performance estimation were both of considerable interest to OBOC participants.

OB-5WWC project progresses into the implementation phase

Open Broadband-5WWC (OB-5WWC) is an Open Source project focused on bringing the full benefits of the 5G ecosystem to fixed-line services and offering a full end-to-end solution to operators. The aim is to create a reference implementation of the Broadband Forum specified Wireless-Wireline Convergence solution for 5G capable Residential Gateways (5G-RGs). There are already key Broadband Forum and 3GPP specifications available to help fulfill the need for 5G and convergence, and a 5G-RG reference implementation will be of great benefit to operators, providing shorter time-to-market for products and reduced development times and cycles.

OB-5WWC also seeks to provide a production grade 5G solution stack capable of integration with OpenWRT/RDK-B frameworks and to provide a reference for testing Access Gateway Function (AGF) and Residential Gateway (RG) test tool development.

Current Progress: The project team worked on the low-level design including WWCd as a key component and clarified modules’ roles. Thanks to the members that have recently joined, the alignment on the architecture for integration with RDK-B has also progressed.

A new development environment was established and Continuous Integration (CI) was operationalized, with exploration taking place of the components for the end-to-end test environment, including AGF and 5G Core. The development includes the solution design of the Control and User Plane transport including the Stubbed AGF test tool, and 5G Wireless Wireline Convergence User Plane Encapsulation (5WE), and the 5G controller (WWCd) providing registration and session management.

Next steps: The project team’s next steps will be to start the MVP implementation of WWCd as a key module, and further improve the test environment. The group continues to align the low-level design with OpenWRT/prpl and RDK-B. 

Members of the project team aim to submit an NPIF to the BUS Work Area to establish an RG architecture Technical Report.

There is now an opportunity for interested parties to offer contributions as we enter this key phase of implementation. The project continues to welcome interested parties, including candidates with software development experience in the C programming language, and radio module and mobile experience. 

For any interested parties (including non-Broadband Forum members) that wish to be part of the project, please sign the project participation agreement online here.
