Broadband Forum Q3 2017 Newsletter
Your quarterly resource for updates on recent activities and our most critical work and focus areas.
As operators look to transform their networks with the greater use of software and virtualization, demand for solutions with associated reference implementations and APIs is growing – the market is now ready for standards-based software deliverables for Open Broadband.
It is with this optimum timing that we have achieved several major milestones at our Q3 meeting. The vBG – the first standard for distributed virtualized Customer Premises Equipment (vCPE) – has been published, and two new Open Broadband projects have been launched as we continue to drive forward the cloudification of broadband networks.
5G continues to be another area of focus for the Forum where our work continues to progress. Work around 5G fixed access and 5G hybrid access is continuing and the next phase in evolution from LTE to 5G transport networking has been published. As this new connectivity is defined, this work will be incredibly important as the divide between fixed and mobile lessens and a holistic broadband network which switches seamlessly between the two emerges.
Significant strides have also been made in our work around Wi-Fi, with the Wi-Fi-In Premise project continuing to move forward. This fills in industry gaps in defining Wi-Fi topologies and management practices (SD-401), and performance tests (SD-398). At this meeting, architectures for multi-device infrastructure with both wired and wireless components were defined, ensuring end-user home networks are truly ‘carrier grade’ as consumer demand for ultrafast, ubiquitous broadband continue to increase.
Of course, all this work would be meaningless if we didn’t inform the industry about it – which is why we’ve organized two Broadband Access Summits, taking place in October. The first of these will be held at Broadband World Forum, in Berlin on Tuesday, October 24. Featuring presentations from AT&T, Verizon, and BT on Fiber Broadband Access, Cyta and Vodafone, discussion which will focus on Gfast and NG-PON2. The second of these events will take place in Las Vegas on Sunday, October 29, with AT&T, Verizon, Ovum, Momentum Telecom, Lumos Networks and DigitalC joining the line-up.
With so much to educate and update attendees on, we have no doubt these sessions will be a huge success, cementing the Forum’s position as the standards organization which will enable the next era of connectivity.
Two Open Broadband projects launched, as virtual Business Gateway standard is published
The first standard for distributed virtualized Customer Premises Equipment (vCPE) has been published as we continue to accelerate our work on Open Broadband, Cloud Central Office (CO) and Software-Defined Wire Area Network (SD-WAN).
The virtual Business Gateway (vBG) (TR-328) accelerates the delivery of new-generation standardized, carrier-class, interoperable business services such as enterprise class firewall and Wide Area Network optimization.
SD-WAN, spearheaded by the Open Networking User Group (ONUG), is enabled by the vBG, which connects to other Broadband Forum initiatives such as CloudCO and the Network Enhanced Residential Gateway. The completion of the landmark specification comes at the same time as the Forum begins work on two major software projects for Open Broadband and makes significant progress on its CloudCO project.
The CloudCO User Managed Objects Framework project creates a cloud-based user interface framework, and a user managed oriented objects template that can be used by all providers. This aims to satisfy customer requirements such as SD-WAN, where the customer wants to have WAN resource telemetry in the user browsers, portals, and for use by their applications. This project will leverage and extend the Forum’s work on the vBG and will use standardized APIs such as DMTF Redfish.
The second key project is Broadband Access Abstraction Open Source which addresses the requirements, architecture, design, and software required to support the virtualization of access device functionality and enabling an open and interoperable unified management interface for access equipment from different vendors. This project will be managed under the Forum’s agile Open Broadband software initiative, allowing for member and non-member collaboration to create a fast feedback loop between the specifications and the software reference implementation that supports them.
Reliable robot demonstrates Deterministic Packet Transport
As the broadband industry prepares for the 5G era, a Deterministic Packet Transport (DTP) demonstration was held. Operating over Layer 2 bridged and Layer 3 routed segments, DPT provides guaranteed delivery with bounded low latency, low delay variation and extremely low loss. As such, it has many use cases including telco systems, mobile networking, industrial networks and automotive networks.
Bringing four components – synchronization, reliability, latency and resource management – the demo in Helsinki used a balancing robot to highlight the reliability element. With DPT, the robot continued to balance even when the connection was interrupted by external influences, such as the lead being pulled out and network issues such as route flapping.
Going Gigabit with Gfast
The number of certified-interoperable Gfast solutions jumped from 7 to 24 in less than three months, as mass deployment of the ultrafast access technology builds.
ADTRAN, EXFO and Viavi have been added to the list of companies whose products have successfully completed the Gfast certification program, run in partnership with the University of New Hampshire InterOperability Laboratory (UNH-IOL).
“From recent leading provider deployment announcements and analyst predictions, there is no doubt that Gfast is gathering momentum, with the value of certified-interoperable systems well-recognized as key for mass-market provisioning of ultrafast broadband,” said CEO Robin Mersh. “Having only announced the first Gfast certification results less than three months ago, it’s great to see the certification program’s rapid and measurable progress.”
ADTRAN, EXFO and Viavi join ARRIS, Calix, Huawei, Metanoia, Nokia and Technicolor, which were the first companies to achieve device certification supported by chip manufacturers Broadcom, Metanoia and Sckipio.
Full steam ahead for common YANG project
The Broadband Forum Common YANG Project Stream made significant progress in Helsinki. A set of agreements have been reached on how to move forward when specifying the Access Node multicast YANG model. From these agreements, the group will derive the required YANG code that will enable the management of related multicast functionality via YANG. This is very important as it enables network and service providers to manage a full triple play service via NETCONF/YANG.
In addition, very good progress was made for several other domains including the management of hardware, alarms, forwarding and Quality of Service. This steadily solidifies the baseline set of Common YANG models that are part of Common YANG Modules for Access Networks (TR-383). This provides a foundation for any YANG-related projects within the Broadband Forum.
The project remains deeply involved with the parallel activities ongoing in the Internet Engineering Task Force (IETF) and in particular discussed how to best align with the new strategic direction of the IETF Network Management Datastore Architecture.
Last but not least, the group also accepted several new test case scenarios related to connecting a Persistent Management Agent (PMA) to the Distribution Point Unit (DPU). These verify the NETCONF/YANG communication between the PMA and the DPU, further removing a number of deployment roadblocks.
Work Area Updates from Helsinki
SDN, NFV and BAS projects progressed by Architecture and Migration Work Area
The team has continued to work on the development of TR-359 Issue 2. Building on the momentum of the NFV enhanced architecture foundations defined by Issue 1, Issue 2 introduces Software Defined Networking (SDN) and greater management and will reflect work done in the CloudCO project. This will increase the applicability of virtualization to the wider multi-service broadband network. Work is progressing well and is expected to go to straw ballot in Q1/2018.
The group is continuing to work on the use cases for Broadband Assured Services. Some progress has also been made in defining a specification for Adaptive Bit Rate Multicast in broadband networks, which will reflect work done in DVB. This will create enhanced efficiency for video and media delivery and enable carriers to offer wholesale delivery to Over-The-Top operators.
A new project on Generation of Application Test Traffic is in the definition stages and expected to commence in Q4.
Broadband User Services puts finishing touches to influential USP
The Broadband User Services Work Area had a busy week putting the finishing touches to the User Services Platform (USP), a protocol and architecture that stands to be even more influential than the Broadband Forum’s flagship standard, TR-069. The group aims to launch USP in the Q4 2017/Q1 2018 timeframe, with a tentative plugfest set for late February. A public draft of the standard can be previewed now at http://usp.technology.
The BUS group took in many new contributions to the Device:2 Data Model, the standardized model for home networking and other connected devices. Improvements to Wi-Fi modeling, measurement and more were considered and pushed into the update pipeline.
To further expand its work on Wi-Fi and the home network, the group, in collaboration with the Physical Layer Transmission Work Area, made great strides with its Wi-Fi-In Premise project, filling in industry gaps in defining Wi-Fi topologies and management practices (SD-401), and performance tests (SD-398). This includes starting work on defining architectures for multi-device infrastructure with both wired and wireless components to ensure end-users’ home networks are truly ‘carrier grade.’
Finally, the group considered additional requirements for home network devices focused around security (SD-409). With the number of malicious attacks against gateways and other connected devices gaining steam, giving providers an easy list of security design requirements and best practices to present to their vendors is critical.
