A Word from our CEO
As the sun sets on 2019, we find ourselves in Central America for our final quarterly meeting of what has been a successful and important year for Broadband Forum. Panama City has been the setting of our first ‘open’ meeting, representing another significant milestone in our evolution as we further open the broadband ecosystem.
We have been focused for a number of years on embracing the best of open source and standards development and in mid-October, we voted on amending our by-laws to transform our organization in tandem with the ever-changing broadband industry. This feels like the correct time to make this transition as we continue to take a leading role in ensuring greater transparency and agility. This meeting has also seen the re-admission of long-term member Huawei for active participation in Broadband Forum technical programs and we are delighted to continue our work with this company.
The outstanding progress we have achieved throughout 2019 continued at this meeting with significant work being finalized across all Work Areas. As Open Broadband, the Connected Home and access technology initiatives continue, 2020 will also see the acceleration of 5G as it moves from concept to reality. With Release 16 set to be concluded by Q2 in 2020, we can look ahead to what we can achieve with Release 17, which highlights the role we have played in the development of 5G to facilitate new services.
In addition, the Broadband User Services (BUS) Work Area is aiming to begin certification testing on User Services Platform (USP) at our next meeting and has worked alongside the Wireless-Wireline Convergence (WWC) Work Area to accomplish remote monitoring and control of 5G residential gateways. A final ballot is also approaching for the SDN/NFV Work Area as Issue 2 of TR-370 nears publication. The Physical Layer Transmission Work Area finalized the first technical review of its Gfast performance test plan, four key project streams are rapidly progressing in the Fiber Access Networks (FAN) Work Area and significant progress is being made in the Common YANG Work Area to ensure smoother interoperability for Broadband Network Gateway (BNG) deployments.
As we move into 2020, we should all pause and reflect on the tremendous work over the last twelve months and feel optimistic about what lies ahead. I want to take this opportunity to thank you all for your continued dedication, and I look forward to catching up at the Q1 meeting in Budapest.
Broadband Forum completes transformation to ‘open’ organization
Broadband Forum has become an ‘open’ organization - making all of its work visible to the industry.
The by-law amendment was passed on 14 October and the transition was confirmed at its Q4 meeting in Panama City, Panama. The move reflects Broadband Forum’s leadership in ushering in an industry-wide evolution to greater agility and transparency that aims to strike the right balance between open source and standards, further opening the whole broadband ecosystem by continuing to drive interoperability and an open market.
Julie Kunstler, Principal Analyst at Ovum, predicted that Broadband Forum’s move to being open would be welcomed by players across the ecosystem of the broadband industry.
“Broadband Forum’s shift to a more ‘open’ organization is a positive one that aligns with the industry trends,” she said. “The move should be welcomed by service providers and vendors as it promotes agility and interoperability, keeping pace with the rapid changes across the communications and media industries.”
For further information about Broadband Forum’s transition, please read the full press release.
It seems fitting that Hungary’s capital city, Budapest is the location for our Q1 meeting which has seen significant progress across our Work Area groups and a fruitful transition of our leadership team. In a location which combines the two cities of Buda and Pest, our members have continued to focus on the convergence of open source and open standards, virtualized and physical network functions, and, fixed and mobile networks to help transform and shape the future of broadband.
This meeting provided the backdrop for a wave of transition, as our annual election took place and we bid fond farewells to colleagues. Newly elected and re-elected members have joined the Board of Directors, our Technical Committee Chair Lincoln Lavoie has resumed his role and Bernd Hesse has been appointed as Marketing Chair. These new leaders will continue to position Broadband Forum as a truly open and collaborative organization.
Bernd’s appointment to Marketing Chair will see him develop our strategy and support our work in a changing technological landscape and the advent of 5G, high capacity PON, the multi-service Connected Home, SDN and NFV. Since 2017, Bernd has established the BASe workshops as key industry events for vendors, operators, analysts and other stakeholders, and we will look to build on this success with the expansion of the BASe event schedule. This growth has been aided by the efforts of our CMO Geoff Burke who is moving onto a new challenge at DZS. I want to express my gratitude for his continued efforts in helping to publicize our ongoing work.
Our Q1 meeting also saw our esteemed colleague and friend Kevin Foster sport the “Last-time Attendee” lanyard as he heads into a well-deserved retirement. Having helped oversee our move to an agile and open organization, Kevin has played a fundamental role in the Forum’s success as a Board Member, contributor and as President and Chairman. I am sure I echo the whole membership’s sentiments when I say you will be truly missed! Kevin has passed the Broadband Forum Chairman baton to long-time member John Blackford, whom I am certain will help us to continue to pave the way for enhanced broadband experience, innovation and standards development. Congratulations John, and best of luck!
With the Q1 meeting completed, our next quarterly meeting and first-ever BASe Australia event are fast approaching, taking us to a new continent as we continue to unlock the ever-growing potential of the broadband industry.
Kevin Foster receives Distinguished Fellow Award and Leadership Award
Kevin Foster, of BT, has been presented with two accolades – Distinguished Fellow Award and Leadership Award – for more than ten years of service and expertise as he steps down from Broadband Forum and heads into retirement.
Serving as Chairman since 2012, Foster joined the board in 2008 before being made President in 2011. He has made significant contributions during this time and played a key role in transforming the Forum.
Howard Watson, Chief Technology and Information Officer of BT, said: “The importance of standards in both the past, present and future of our broadband industry cannot be underestimated and Kevin’s work is an excellent example of why operators should get involved.”

A 2019 recap from our Technical Committee Chair: Monumental progress made across all Work Areas
As 2019 draws to a close, it seems a fitting time to look back at the successful progress that has been made across all Work Areas at Broadband Forum this year. Looking ahead to next year, a number of Work Areas are sending work to straw ballot and getting their work into the final stages, including the first technical review on our vOMCI specifications (WT-451), the requirements and protocol specifications for disaggregated BNG (WT-459), and Gfast performance testing (WT-380).
Helping facilitate adoption and deployment of our USP protocol, we saw the launch of the Open Broadband – USP Agent (OB-USP-Agent) project with its Blackbird Release being wrapped up at the meeting here in Panama City.
At Mobile World Congress 2019, we released the industry’s first carrier-grade Wi-Fi performance testing standard (TR-398), which hit the interests of a host of operators and equipment vendors which participated in the drafting of the standard.
April and May saw the publication of the nodal requirements for hybrid broadband networks (TR-378) and YANG data models for management of ITU-T PON (TR-385), that were quickly consumed by our Open Broadband – Broadband Access Abstraction (OB-BAA) project, leading to the Broadband World Forum (BBWF) 2019 demos. The Application-Layer Test Traffic Architecture and Requirements (TR-421) was published in August, with work continuing in the Performance, Experience, and Application Testing area – exciting things are coming, I promise.
There were demonstrations across the Connected Home, Cloud Central Office (CloudCO) and Broadband QED at BBWF, which was the largest number of demos based on Broadband Forum work showcased to the industry at one location at any one time. Way to go team!
It’s been a tremendously busy year for the Forum as we finish strongly in Q4. The rapid pace of the Forum’s work has been made possible thanks to the dedication of our participants and community, so please join me in “raising a glass” to toast their success and the possibilities 2020 will bring.
- Lincoln Lavoie, Broadband Forum Technical Committee Chair

WWC needs you (if you’re a CPE vendor)!
As the WWC Work Area moves forward with specifying a new class of Customer Premises Equipment (CPE) – the 5G-RG – it is calling for CPE vendors to participate in the work.
The 5G-RG will be designed to specifically integrate with a 5G core by employing a 5G signaling stack and possibly providing support for devices using 3GPP procedures in the home. It may also have a fixed WAN interface, LTR or NR WAN interface or both fixed and wireless interfaces for hybrid access.
CPE vendors are required to participate in the project to ensure that the specifications ultimately generated are clear in order to facilitate simple implementation and provide important input and advice in regard to technical choices. Vendors who decide to participate will be given opportunities for downstream deployment options and networking opportunities with other vendors in the WWC ecosystem. As the work evolves, interoperability and certification options will also be explored.
The work already involves major carriers in each of the Asia, North American and European markets.
If you are a CPE vendor and would like to get involved in this work, please contact Work Area Director David Allan at david.i.allan@ericsson.com.

USP certification testing on the horizonSignificant steps forward for BUS Work Area in Budapest
- Target: Help service providers control the connected home business model.
- Progress: The group has started two new projects: Translation Rules & Tools for YANG Schema Representation of CWMP / USP Data Models (WT-473) and In-Home SDN Configuration & Control (published as part of an upcoming WT-181i2 Amendment).
- service providers control the connected home business model.
- Progress: The group has started joint work with the prpl Foundation to explore how TR-369 can be used to enable “microservices” in home gateways. Work has continued on TR-398 and the group is working Outcomes: The group plans to launch certification testing for USP in Q1 2020 and is finalizing work with the WWC Work Area to add device requirements and Device:2 root data model components related to the 5G Residential Gateways.finalize requirements for a managed 5G fixed wireless gateway.
- Outcomes: A certification program is set to be finalized for fully integrated USP Agents in Q2 of 2020.
The Broadband User Services (BUS) Work Area has started two new projects. The first project will result in the creation of translation rules and tools for the generation of YANG schema representations of the existing CWMP and USP data models. This project has huge upside potential as many operators are looking for a YANG representation of the data that traverses their network. The second project will result in updates to the Device:2 root data model to expose SDN concepts for configuration and control of devices within the home network. This project will specifically target the modeling of Open vSwitch (OVS) concepts in the form of the OVSDB database schema being incorporated into the Device:2 root data model, which opens up the management of OVS-based devices to both TR-069 (CWMP) and USP.
Moving forward, the group plans to launch certification testing for USP in Q1 2020. The group is also very focused on finalizing joint work with the WWC Work Area related to the 5G Residential Gateway, specifically as it pertains to adding new device requirements for 5G Residential Gateways within a new release of the TR-124 specification and creating new Device:2 root data model components for the remote management and control of the 5G Residential Gateway.
had an exciting week entering into joint work with members of the prpl Foundation to explore how Broadband Forum's powerful new User Services Platform (USP) (TR-369) can be used to enable "microservices" in home gateways, creating truly interoperable "app-enabled" Wi-Fi routers that can obtain easily deployed, activated, and managed third-party services like Wi-Fi analytics, security, and more. This is an incredible step forward for something that has been somewhat of a "holy grail" for the broadband and consumer electronics industries for some time.
The group is also on track to finalize service elements and requirements for a managed 5G fixed wireless gateway in collaboration with the WWC Work Area. Providers and manufacturers will have clear guidelines for how to build, deploy, and maintain these devices through a harmony between traditional broadband networks and mobile networks.
Furthermore, the group also continued work on the next version of its TR-398 standard that has created a way for providers and vendors to properly evaluate Wi-Fi routers and Access points (APs) for performance. The next version will include tests and metrics for Wi-Fi 6 enabled gateways.
The USP has been gaining steam in the industry at an incredible pace. In addition to the open source USP Agent published by Broadband Forum, the group is on track for a certification program to be finalized for fully integrated USP Agents in Q2 of 2020Finally, work is also continuing on the next version of the popular Wi-Fi In-Premises Performance Testing suite (WT-398 Issue 2), which will incorporate tests for Wi-Fi 6 (802.11ax) and Multi-AP deployments.

OB-BAA
adds its multi-vendor, SDN capabilities to the Broadband Forum’s CloudCO showcase eventissues Release 3.0 to ease migration to cloud-based networks
OB-BAA has issued its third release that brings needed capabilities for service providers to monitor their networks with existing management systems or SDN enabled management and control systems. In addition, this release continues enabling accelerated migration to cloud-based access networks by expanding the breadth of vendor implementations by providing capabilities to adapt vendors’ SNMP-based Access Nodes.
Specifically, this release provides the following enhancements:
- Service assurance capabilities to include collection and transformation of performance monitoring (PM) data into standardized YANG data models. This includes storage of the translated PM data into a common data lake. The BAA layer provides an IP Flow Information Export (IPFIX) data collector for use with Access Nodes that support Broadband Forum’s standard for PM data collection. In addition, the notification capabilities are enhanced to allow for subscriptions for notifications to monitor events within the network.
- Integration with existing SNMP-based Access Nodes by providing a SNMP adapter framework.
- Operation of the BAA layer that includes the capability to determine how well vendors’ implementations conform to the standard YANG modules defined in the Broadband Forum's TR-413 ‘SDN Management and Control Interfaces for CloudCO Network Functions’
In addition to the capabilities offered by the current release, the OB-BAA project has experimented and demonstrated how the BAA layer and Broadband Forum's standardized YANG modules can be used to relay traffic from the Access Nodes toward SDN controllers in order to steer traffic. The next release is scheduled to enhance the capabilities of this feature by making it available as part of the BAA layer.
OB-MAP continues work with prplMesh to refine topology database and APIs
At this year’s BBWF, the Open Broadband – Broadband Access Abstraction (OB-BAA) project showcased it’s multi-vendor, multi-protocol adaptation, zero-touch and automation capabilities of the CloudCO BAA layer which showed how the BAA layer is used to automate zero-touch service creation, activation and relocation.
It also demonstrated how the BAA layer accelerates migration to cloud-based access networks by expanding the breadth of vendors by leveraging its ability to facilitate co-existence, seamless migration and adaptation to an increasingly wide variety of software defined access technologies and implementations. Building on the success of BBWF 2019, the OB-BAA team is adding new SDN capabilities to the BAA layer that eases the reporting of alarms and collection of performance data from access nodes which is scheduled for release in February 2020.
A video interview featuring perspectives from Mauro Tilloca of TIM, Broadband Forum Board member and a key service provider participant in CloudCO/OB-BAA demo, can be seen here.
A video summary of OB-BAA progress to date and plans for the future from BAA leader Tim Carey can be seen here.
OB-MAP defines high level architecture for topology database

The architecture includes a whole-network topology database and which allows for definition of a third-party controller . The project is now working on the details of and other uses. This architecture also requires three sets of APIs: between prplMesh and a controller, prplMesh and the topology database and the controller and topology database. In addition, we are working on the detailed design of the database. The database will enable granular control and troubleshooting of the local network
The group has been reviewing SoftAtHome’s gMap database to see if it would be suitable as the topology database. That determination will impact the syntax of the APIs. After the decision is made on the database, the group will decide how to make the database accessible through USP and how other local applications will access this. Access to this database may be enabled through the “microservices” project that the prpl Foundation is driving into the BUS Work Area.
The project also continues to ensure that all physical layer technologies are supported in the context of the database and network topology.
In the future, OB-MAP expects to produce vendor extensions to the IEEE 1905.1a specification that will provide carrier-grade capabilities enhancing EasyMesh operation in operator deployments. Once these are done, we will also deliver certification requirements for these BBF Broadband Forum extensions that would lead to a certification program.

- Target: To help service providers deploy equipment that will give provide a better quality of experience Quality of Experience (QoE) for their end-users.
- Progress: The Physical Layer Transmission group Transmission (PHYtx) Work Area finalized the first technical review of its Technical Review of the Architecture and Requirements for Fiber to the Distribution Point recommendation. The Gfast performance test plan , as well as, adding new use cases to reached the completion of the twisted-pair performance targets. The remaining use cases for fiber access extension over existing copper infrastructure became more detailed. New Dynamic Time Assignment (DTA) testcases were added to the Gfast certification plan.
- Outcome: Four documents have passed final approval and have been published on the Broadband forum website. They are TR-114 Issue 3 Amendment 3, TR-115 Issue 3 Amendment 2 and TR-249 Issue 2 which all relate to VDSL2-LR (Long Reach) and TR-208 Issue 3, covering the Performance aspects for In-premises Powerline Communication Systems.
VDSL Long Reach greatly increases the reach of VDSL, allowing the operator to have more deployment scenarios and replace the legacy ADSL.
- Three documents are now ready for straw ballot review. These are WT-380, WT-338i2 and WT-419. The document WT-301i2a1 is ready for final approval.
The twisted-pair performance requirements have been included in the 'Gfast performance test plan' (WT-380) proving that Gfast systems can reach data rates beyond 1Gbs for the 106MHz profile and beyond 1.6Gbs for the 212MHz profile. This document is now ready for its second Technical Review. Scheduled for publication from the Q2 2020 Meeting, this document provides operators with a means to evaluate the twisted-pair performance of Gfast systemsThe test framework of WT-380 (Gfast performance test plan) focusing on single line tests has passed its first technical review. This test framework enables the Work Area to start the measurements for setting the Gfast performance requirements, targeted to finalize during the first quarter next year. The next step is to define the test framework for multi-line performance measurementsperformance targets for coax based Gfast systems and the test framework for multi-line performance requirements.
The Reverse Power Feed (RPF) Test Plan (WT-338i2) has been completed and is ready for Technical Review, and now includes performance requirements for Distribution Point Units operating with RPF.
The next revision of the 'Gfast certification test plan' (DTP-337) is on its way. This revision now includes certification of software download, while operation with dynamic time assignment ( DTA ) improves the response times and throughput of the Gfast connection and verification of the accuracy of test parameters is approaching. First implementations of DTA have already been undergoing tests at the latest Gfast plugfestPlugfest.
Projects Project WT-419 /SD-419 further detail (Fiber Access Extension Over Existing Copper Infrastructure) detailed the remaining use cases and requirements for extending fiber access over existing local copper infrastructure. This work will help telecoms operators the document is now ready for Technical Review. WT-419 provides telecom operators with an overview of technologies they can use to offer fiber-like speeds on their existing copper infrastructure where the installation of fiber is not yet economicalnot yet economical.
A secure Dying Message was included in the Architecture and Requirements for Fiber to the Distribution Point recommendation (WT-301i2a1). This solves a security vulnerability that may occur with the reception and processing of an unencrypted, non-validated or non-authenticated Dying Gasp message. This technical recommendation is ready for its final approval.

Issue 2 of TR-370
nears publicationpublished and WT-408 heading to straw ballot
- Target: To drive the migration of SDN and NFV into all aspects of broadband networks to facilitate the agile deployment of new customized distributed broadband services and applications.
- Progress: vOMCI (WT-451) has progressed to a position where we are ready to go to straw ballot. Straw ballot resolution is virtually complete for TR-370 Issue 2 with only a few homework items left to agree on.
- Outcomes: We have moved forward significantly on WT-436 – Automated Intelligent Management (AIM) Project Stream, specifying how the Access and Home network will utilize AIM in the CloudCO context and other deployment models.
The SDN/NFV Work Area now has ten separate projects in flight following the approval of the latest Metro Compute Network document. This work requires an editor in order to progress, if there are any interested parties, please contact the Work Area directors.
Progress has been driven by a tiger team on CloudCO Migration topic (WT-408) addressing the gaps with the objective of going into straw ballot following the Q1 meeting.
For WT-436, the group has reviewed various external bodies’ framework and agreed to include the best parts of each of these into the working text.
On WT-451, the group is still working towards a Plugfest to validate and this will drive the timescales for publication of this document.
We should complete final ballot before the next meeting for Issue 2 of the Fixed Access Network Sharing (FANS) (TR-370). This updated document adds cloudification into the Fixed Access Network Sharing (FANS) process and aligns the document with the CloudCO framework, as defined by the SDN/NFV Work Area.- distributed broadband services and applications with greater operational efficiency and lower cost.
- Progress: The CloudCO project encompasses an expanding set of deliverables addressing: Reference Architecture; Interfaces specifications; Software reference implementations; Coexistence and Migration; and exemplary implementations and testing illustrated in the figure below. Some of these activities involve other Broadband Forum Work Areas and this will continue to expand.
- Outcomes: TR-370 Issue 2 on Fixed Access Network Sharing has been published. TR-384 Cloud-based Framework (CloudCO) work on Issue 2 has started. WT-408 Migration and Coexistence decision on Straw Ballot readiness will be made in the next four weeks. It includes a strategy of either migrating existing Multi-Service Broadband Network (MSBN) and discusses when and how to introduce the CloudCO infrastructure. It also provides examples of how functionality in the management, control and user planes can be migrated toward CloudCO.
WT-435 NETCONF Requirements for Access Nodes and Broadband Access Abstraction draft was completed with more details on selected requirements and Use Cases to align with operators’ needs and to clarify interdependencies among requirements. A teleconference call will be scheduled to review revisions and determine straw ballot readiness.
WT-436 Access & Home Network O&M Automation/Intelligence agreed on a framework for the specification in January and draft text content for Broadband Forum framework is being progressed via a tiger team including terminology consistency issues.
WT-451 vOMCI for New Access Nodes started Straw Ballot comment resolution. Final approval is contingent on verifying successful multi-vendor WT-451 Plugfest interoperability that includes vendor participants and the OB-BAA reference implementation.
WT-454 YANG Modules for Access Network Map & Equipment Inventory. The purpose of this Working Text is to define YANG data models for access network map and Equipment Inventory applicable to the BAA layer and the Access SDN Management and Control. Current results are that two YANG models have been accepted and source code uploaded to Broadband Forum Open Broadband. Ahead of the Q2 meeting, the Work Area is hopeful the gaps will be addressed, and the group will determine if it is ready for straw ballot resolution.
In the future, new work will be starting on:
- WT-466: Metro Computing Networking
- WT-474: Subscriber Session Steering which may involve other Work Areas
More information about the SDN/NFV Work Area can be found at: https://wiki.broadband-forum.org/display/BBF/SDN+and+NFV.
The group also says farewell to Work Area Co-Director Chris Croot, of BT, and welcomes Bruno Cornaglia, of Vodafone, into the position.

WWC set to roll out finalized documents of Release 16 in Q2
Work on 5G FMC progresses with work on Release 16- Target: Address the needs of converged operators, which have both wireline and mobile networks deployed and are in a position to leverage all their assets with combined subscriber offerings.
- Progress: The Wireline-Wireless Convergence WWC Work Area (WWC) is aggressively looking to complete completed populating the documents that will provide the normative specifications for the equipment that will connect wireline to the 5G core and the CPE it will servefirst set of documents at the Q1 interim meeting in January. These documents will be the first normative specifications for the equipment that will connect wireline to the 5G core and the CPE it will serve. The Work Area is now immersed in the Straw Ballot process whereby the documents go through a detailed review as the next step to finalization. The area’s target is to substantially have the work for Release 16 complete by year end, and the documents finalized and published early with finalized documents rolling out starting in Q2/2020.
- Outcomes: Complete solutions to Fixed Mobile Convergence (FMC) WWC will be delivered in the Release 16 timeframe as originally planned.
Work in the WWC Work Area is now increasingly focused on finalizing the technical details that require specification, addressing the needs of converged operators with both wireline and mobile networks deployed who are in a position to leverage all their assets with combined subscriber offerings. This work will allow converged operators to provide a uniform experience to their customers irrespective of the access or appliance they are using. This will be supported by a common and streamlined back office and control plane.
Broadband Forum and 3GPP are now deeply engaged in ensuring the myriad of technical details required to generate detailed specifications are addressed. This is in respect to CPE network equipment and changes to the 5G core.
Broadband Forum is taking an important role in developing 5G, making recommendations for the connection points between the fixed and 5G mobile core networks in order to drive core convergence. At this point in the FMC WWC work, the group has shifted from making documenting the decisions to documenting critical review of the decisions.
Joint sessions were held across the Technical Committee examining other aspects of 5G where Broadband Forum’s expertise could be applied. In particular, with BUS, which saw the go forward plan to execute CPE changes for FMC firmed up. This will enable USP, and its predecessor, TR-069, to contribute to the value proposition of FMC and 5GWWC is also working with BUS to extend the TR-181 data models for 5G to leverage TR-069/TR-369 as part of WWC. The Work Area also did a final push to get the CPE changes to a state of completion and critical review.
WWC is deeply engrossed in the normative phase of this work, with the first set of specifications set to be published in Q2/2020.
