Focus shifts to Quality of Experience and service-orientated ecosystem at SPAC session

A productive Service Provider Action Council (SPAC) session during the first day of the quarterly meeting sparked debate and garnered key insights from many in the audience, both face-to-face and virtually. The session focused on what value can be derived from a services-led approach to standards work for the service provider community. This would, of course, have to be reviewed and refreshed in alignment with other Standards Development Organizations (SDOs). Broadband Forum outlined its desire for agile network service delivery from Proof of Concept to real-world deployments, monetization and differentiation of services and a multi-service broadband network.

When broadband speed and bandwidth is no longer an inhibitor, Quality of Experience (QoE) will be regarded with equal importance or even as more important, was the message from the Broadband Forum leadership team. It was observed that traditional revenue was declining with the majority of employers willing to adopt home working and harness new revenue models that keep residential broadband and the home worker separate. Broadband Forum outlined its strategic approach to shift from typically connection-based broadband to a service-orientated ecosystem, and the requirements across the network to deliver an end-to-end QoE service model.

The session, which was opened to all those in attendance, including members and guests, covered an array of topics and pinpointed notable areas that the organization can focus on moving forward. This included the requirement for recognized, defined and appropriate QoE metrics and the need to actively engage with global regulators as regulations can have an impact on price and implementation. How to offer differentiated service offerings to each customer was another discussion point, as well as delivering improved monitoring that enables autonomous networks.

The common conversation was that the Forum needed to collaborate with other SDOs, as well as recognize the digital divide and understand that not everyone has the same QoE. In the future, Broadband Forum must highlight how it can support and educate the whole industry to deliver broadband growth to all of those underserved locations and communities. Another area of discussion revolved around addressing niche markets, such as gaming, with improved QoE and consistent latency. With the average consumer not understanding what latency is, marketing teams will have to simplify to express this coherently to their customers.

Moving forward for future quarterly meetings, there will be an open discussion session for guest keynote speakers to address hot topics or analyst insights, and we invite guests that might be interested in discussing a trending topic to contact the team at info@broadband-forum.org.

BASe industry education and events continues at full steam ahead 

The BASe series continues at a breakneck pace in its mission to inform and educate the industry. During 2022, there will be a total of 14 vBASe Webinars, seven BASe Knowledge Webinars, a vBASe State of Broadband Summit, vBASe APAC, and seven face-to-face events. A special thank you goes out to all participants at our UFBB 2022 in Den Haag, The Netherlands, with 33 panelist sessions across three days and a great turnout of 100 service provider and vendor technologists. UFBB was a great precursor ahead of welcoming our members back to in-person quarterly meetings.

Across the three days, we attracted a number of insightful panelists, and the interaction during the workshops and the breaks proved yet again that nothing can replace the success of in-person return. It goes without saying that the whole BASe team would like to thank our sponsors, trade associations and attendees who travelled and participated in the event.

Thank you to our BASe 2022 sponsors!

Thank you to our Q3 Meeting sponsor, Nokia!

Nokia’s General Manager, Broadband Networks’ Geert Heyninck highlighted that there is a long history of fixed networks in Antwerp. Geert advised that Broadband Forum’s work has played an instrumental role in defining universal specifications and increasing the number of overall global broadband subscribers.

The insightful presentation also outlined the change in thinking from Fiber-To-The-Home to Fiber-To-Everything. This disruption is being enabled by the technology evolution, according to Geert, such as infinite capacity that can serve many applications, to the transition to Software Defined Networking, the need for low-latency and more sustainability. These are key factors behind this shift in the need for Fiber-To-Everything.

The audience was informed of another important trend, which was the introduction of new and smaller players through investment, government funding and infrastructure builders.

Geert informed the attendees that the industry needs to play an increasingly important role to accelerate smaller fiber rollouts by new players, through reference implementations, deployment guidelines, simplified configurations and align with non-telco industry bodies.

The 5G Project Stream continues to progress is finalizing the two specifications, WT-457 (FMIF Functional Requirements) and WT-458 (CUPS for 5G Fixed Mobile Convergence), both of which expand the deployment options for 5G WWC, with those documents entering Straw Ballot by the end of the year. The new IMS for 5G-RG Project Stream addresses 5G-RG IMS Voice support, starting 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.

For 5G-RG Hybrid Access enhancements , it was also agreed as a Phase 3 study item. A joint session on 3GPP and non-3GPP device management requirements was held together agreed that the group would expand the work to address the TR-181 Data Model Extensions for 5G-RG supporting ATSSS. The group jointly held a session with the BUS Work Area in the context of the Broadband Forum cooperation with 3GPP on the subjectto introduce the 3GPP’s Release 18 Study output, and this is expected to facilitate a WWC study around “Devices behind the RG”.

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. Catch up on the Quality of Experience in an Wireless Wireline Converged Network webinar that took place on March 17. The WWC Work Area has an upcoming webinar on September 27 to update the broadband industry on the IMS for 5G-RG progress.

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.

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 published the Essex Skipper 5.0 release in April 2022. The latest release is another step that enables service providers to welcome the benefits of cloudification to their networks, but just as importantly, it offers a migration plan from their existing network investments. The release includes work on policy-based authentication within the operator’s cloud network of Optical Network Units (ONUs) as operators seek to deliver a seamless customer experience. This encompasses the ability to automatically discover and maintain virtualized network functions used by the BAA layer by interfacing with the environments that host the virtualized functions.

Release 5.0 also enhances the functionality for disaggregating the management of ONUs from the OLT into the operator's network with new features to handle ONU alarms. The additional enhancements to the virtual ONU Management Control Interface (vOMCI) solution were made in support of future Broadband Forum vOMCI Plugfests. The latest work provides enhancements and fixes to the existing OB-BAA software that scale testing for a single Optical Line Terminal (OLT) device, and has created more than 512 ONUs and connected and aligned 127 ONUs.

The OB-BAA project team is currently working towards Release 5.1 as we prepare for the Broadband World Forum demo later this year. This will encompass microservice discovery and integration with shared datastores and scale testing of 10,000 ONUs.

OB-MAP and prpl Foundation continue promising collaboration

The Open Broadband – Multi Access Point (OB-MAP) project and the prpl Foundation’s prplMesh project have completed 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 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 internal Messaging Transport Protocol (iMTP) in the context of prplOS.

Finishing touches on Falcon Release by OB-USP-Agent team

Current Efforts: The OB-USP-Agent team has been putting the final touches on its Falcon Release (Release 6) with a release date targeted for the end of June. This release incorporates key features related to the initial support for USP End-to-End Session Contexts. These features cover the USP Record Segmentation and Reassembly mechanism, USP Connect records, and the USP Disconnect record. This latest release also incorporates enhancements introduced in Version 1.2 of USP, the ones specifically related to the Get and GetSupportedDM message updates.

Future Plans: The team plans to begin scoping work for Release 7 in July.

Eighth release from the OB-UDPST project team adds new measurement algorithm for faster and reliable measurements

Current Progress: The OB-UDP Speed Test (OB-UDPST) project team delivered its eighth public release (7.5.0) on-time on May 6, 2022. This release introduces a new/optional Load Adjustment Algorithm for challenging circumstances, such as persistent competing traffic and non-congestion-related Loss.

The major new feature in this release, was anticipated by the version 9 protocol in release 7.4.0:

• Optional Load Adjustment (Search) Algorithm, Type C, briefly described as "Multiply and Retry"
• The "fast" ramp-up is now a multiplicative rate increase to congestion, reaching 1 Gbps in less than 1 second
• The "fast" ramp-up can be re-tried when conditions warrant to ensure that the Max IP-Layer Capacity is reached
• This algorithm supports a search over the full range of rates, even if the subscribed rate is more than 1 Gbps
• The Type B algorithm remains the default for testing that does not benefit from "Multiply and Retry" aspects

The new Type C Algorithm satisfies requests to support test durations of less than 10 seconds, and permits measuring the Maximum IP-Layer Capacity more reliably, even on Mobile access with more variability than Fixed access.

This release also includes an extended Sending Rate Table, which allows testing of access rates up to 40 Gbps.

Future Plans: Next steps likely include a supplemental release, 7.5.1, coming soon. This release will pick-up feedback from users of one of the earlier releases. Issue 3 of TR-471 plans to incorporate all of the improvements and features deemed useful in the OB-UDPST project.

Now that the Internet Engineering Task Force (IETF) has published RFC 9097: ‘Metrics and Methods for One-way IP Capacity’, the IP Performance Metrics Working Group has adopted the OB-UDPST protocol specification. The OB-UDPST project team will follow the IETF IP Performance Measurement (IPPM) development and comments closely.

OB-5WWC project defines high-level software architecture in Q2

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 fixed-line 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 RG test tool development.

Current Progress: A number of achievements have been made this quarter, including high-level software architecture being defined with key components and their roles identified. This includes developments on Control Plane Transport and the Wireshark enhancements for the specifications from the Broadband Forum. Wireshark is the industry-standard tool that is continually used by implementers.

High-level design for OpenWRT integration was completed, this includes the design for Unified Configuration Interface (UCI), ubus configuration and mapping configuration to TR-181. A formal development environment was defined, and exploration took place of the components for the end-to-end test environment, including AGF and 5G Core.

Next steps: The detailed design including WWCd as a key component will be addressed in the months ahead. The project team are hopeful that development will soon begin. This 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 providing registration and session management.

There is now an opportunity for interested parties to offer contributions to implement the architecture and component design already established. The project remains open to all 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.

Eighth OB-UDPST makes progress with contributions coming from new sources

Current progress: Now that the Internet Engineering Task Force (IETF) has published RFC 9097: ‘Metrics and Methods for One-way IP Capacity’, the IP Performance Metrics Working Group has adopted the OB-UDPST protocol specification as a working group draft and received an early review from the IETF Security Directorate. Many aspects of the protocol will be improved as the OB-UDPST project team addresses the review comments, such as the revised four security modes of operation needed, expanded authentication of the Control Phase messages, key management procedures and more secure firewall operations made possible by small protocol changes. The plan is to keep the UDPST running code and the Internet Draft in-sync.

Meanwhile, the University of New Hampshire InterOperability Laboratory (UNH-IOL) hackfest approved a project for UDPST. Broadband Forum Technical Chair Lincoln Lavoie led a team of hackers working to build a CI testing system for UDPST, identified as a need earlier this year. This project is a basis for automated regression-testing of new patches and Releases, and should minimize time-consuming manual work. Integration with the Bamboo platform will follow the review by the project team.

Future Plans: The next steps are likely to include a supplemental release, 7.5.1, coming soon. This release will pick-up feedback from users of one of the earlier releases. Issue 3 of TR-471 plans to incorporate all of the improvements and features deemed useful in the OB-UDPST project. The OB-UDPST project team will follow the IETF IP Performance Measurement (IPPM) Internet Draft development and comments closely.

App-enabled services gateway, network latency and fixed broadband growth are key themes over the last quarter

Oliver Johnson, CEO of Point Topic produced a blog on the number of global fixed broadband subscribers continuing to grow. Oliver highlighted the growth markets, compared regional market shares and the countries that are leading the way in terms of fixed broadband penetration.

Ken Ko, Managing Director of Broadband Forum discussed the importance of network managed latency and outlined the key challenges and opportunities that the industry faces. As we continue to recognize and address the viewpoint that speed alone does not define a broadband subscriber user’s experience, there is a shift in focus among service providers on Quality of Experience (QoE), new Average Revenue Per User (ARPU) growth opportunities and service differentiation.

A key project that has been introduced by the Broadband Forum is the new WT-492 standard ‘Software-Based Architecture for the App-Enabled Services Gateway - Design Principles.’ An article on this project by Craig Thomas, Vice President Business Development and Strategic Marketing at Broadband Forum was published in IEEE Xplore. Craig advised how service providers’ business plans can be revolutionized by looking towards end-user network gateways, such as Wi-Fi routers, as a platform to unlock a myriad of third-party applications and services,

Craig was also interviewed by ViodiTV on the new project with the new standard presenting an opportunity for “app-store-like” functionality for end-user services, and helping service providers effectively deploy, activate and manage third-party applications. This app-enabled services gateway will allow service providers to differentiate and scale their business models to provide a more customizable offering to each subscriber

YANG, USP 1.2, vBASe and multi-vendor interoperability were all topics for discussion in Q2

Joey Boyd and Sven Ooghe, Co-Directors of Broadband Forum’s Common YANG Work Area teamed up to inform Broadband Forum readers how the Common YANG Work Area work is delivering greater interoperability to the broadband industry. They concluded that operators can deploy new technologies with renewed confidence and improved interoperability, thanks to YANG.

One of our latest blogs also explored one of fastest-growing standards for connected device management and control in the connected home industry. A blog by Jason Walls, QA Cafe, Chair of the Broadband Forum Connected Home Council and BUS Work Area Director discussed how USP 1.2 is unlocking the full potential of the connected home market.

Tiffany Groves, Marketing Coordinator at Broadband Forum and Rhonda Heier, Director of Membership Development at Broadband Forum revealed that Broadband Forum is hosting a combination of in-person and virtual BASe events, due to our growing number of BASe sponsors. The Broadband Acceleration Seminar (BASe) series will continue to focus on three main broadband ecosystem elements.

What is QoE and why does it matter? was the blog from Craig Thomas, VP Marketing & Business Development at Broadband Forum that outlined what we are doing for Quality of Experience and how it is different to Quality of Service. Wrapping up Q2 was a blog from Jonathan Newton, Principal Network Architect at Vodafone’s Fixed Access Centre of Excellence. Jonathan told readers that WT-474 will deliver an open standards approach to the architecture and data models to enable network capability for flexible and dynamic real-time decisions about the placement of individual subscribers. Broadband Forum is currently working on WT-474, which is introducing Subscriber Session Steering and dynamic subscriber placement.
