Broadband Forum kicks off BNG Disaggregation project

The Broadband Forum is launching a new Broadband Network Gateway (BNG) project to define the architecture and requirements for a disaggregated BNG control plane and user plane which separates the control plane and data plane.

BNG disaggregation is expected to bring benefits such as centralized locations for configuration and IP address management, leading to faster delivery of new services. The work will also ensure the control plane and user plane can be easily scaled according to customer demand.

"As demand for both broadband and bandwidth-hungry video applications grows, the disaggregation of the BNG for scalablity is critical to mitigate issues created by distributed BNG deployments. Over the years, BNGs have also had to evolve to support new functionalities such as management of multiple types of accesses, transport encapsulations and customers. This work will ensure flexible scalability through a simplified and agile architecture," stated Kevin Foster, Chairman of Broadband Forum.

Broadband Forum targets PON Virtualization for 5G Fronthaul

The Broadband Forum and NTT are undertaking a project to standardize the virtualization of PON networks to support the delivery of Time Critical Applications (TCAs), such as 5G fronthaul.

The project, which was initiated by Forum member NTT, is called PON Abstraction Interface for TCAs. It looks at how SDN and NFV can be applied to Optical Line Terminals to disaggregate PON functions to functional modules with open interfaces. The first phase will define the disaggregation policy and functional requirements of interfaces to disaggregate PON functions which need time-critical processing, while the second phase will define the detailed specifications of the interfaces as Application Programming Interface (API) sets.

“As users’ usage changes, both in regard to the different services required and the amount of data coursing through fiber networks, operators need to update their PON networks, including by adding TCAs,” said Akihiro Otaka, Executive Manager at NTT Access Network Service Systems Laboratories. “This used to require the remake of PON equipment for each service, but should be done via a software upgrade in the near future to improve cost-effectiveness. With demand for this increasing, it is important we ensure there are standards in place to achieve a vendor-agnostic system and ensure mass deployment of this new system architecture, which is essential if we are to deliver agile and flexible next-generation broadband networks for emerging services.”

“As we work to meet the demand for new services, faster connectivity and more bandwidth, our focus is shifting from the fixed network to a holistic broadband network,” said Robin Mersh, CEO of Broadband Forum. “We know fiber will play a huge role in the delivery of 5G and this project looks to define that role and make it possible for operators to offer fronthaul services, among others, via their PON networks. This makes the work important not just for the broadband industry but the telecoms market as a whole and it can only be achieved on a wide scale through collaboration and standardization.”

Broadband Forum progresses on Cloud Central Office and 5G

The Broadband Forum announced at its second quarter meeting in Taipei significant progress on five projects relating to the realisation and implementation of Cloud Central Office (CloudCO), which is scheduled to be launched later in the year, with preparations to test the implementations under way at the first Open Broadband Lab in Asia, which was announced recently.

The Broadband Forum's CloudCO projects encompass architecture and hardware, as well as software implementation and migration, and represent one of the first use cases for the recently launched Open Broadband initiative designed to provide a new platform for the integration and testing of broadband-related services.

The forum is also focusing on key use cases for 5G networking, including hybrid wireless wireline networking in access and home networking, network slicing and projects for backhaul and fronthaul transport.

Additionally, further aspects of the forum's Broadband 20/20 vision include the evolution of TR-069 into a user services platform for premises' networks and compute resources, for example entertainment and the Internet of Things (IoT), which are scheduled to be released later this year.

During the second quarter meeting a number of specifications were approved, including TR-390, which defines standardised mechanisms for performance measurement and is designed to enable service providers to gain greater insight into how the access network is performing.


Unveiled in August last year, the CloudCO projects aim to enable functionality that can be accessed via a northbound API and cover:

1.         Definition of a reference architectural framework for the CloudCO specifying the behaviour of functional modules.

2.         Definition of interfaces (potentially including APIs, Yang or other schemas and protocols) between the functional modules.

3.         A software reference implementation of the framework to allow code to be upstreamed to open source organisations in the future, plus enable VNF vendors to test functions on the reference implementation.

4.         A project on CloudCO coexistence with, and subscriber migration from, legacy broadband architectures, such as TR-178-style architectures.

5.         A project to deliver a hardware reference implementation of CloudCO based on deployment considerations.

Broadband Forum Completes FTTdp Work

The Broadband Forum completed work on the management of Fiber to the Distribution Point (FTTdp), which aids in the management of fiber-fed nodes in the periphery of the access network.

At the Broadband Forum’s quarterly meeting in Mexico, it was agreed that the FTTdp YANG management model was ready for release exclusively to members for testing in network equipment. This is the Forum’s first software project written in the YANG modelling language.

“This is great news for our members whether they be service providers, vendors or test houses,” said Broadband Forum CEO Robin Mersh. “By adopting YANG modelling we are in the process of moving the management of FTTdp from the drawing board into the network, helping to drive open interoperability between different devices. This means service providers can offer competitive ultrafast services such as G.fast.”

Regarding G.fast, the Forum approved the University of New Hampshire Interoperability Labs (UNH-IOL) as a test facility for the latest G.fast plug-fest – paving the way to the industry’s first certifications.

“The success of the Forum in accelerating broadband innovation would not be possible if it weren’t for the expertise and energy of its members,” said Kevin Foster, Chairman of the Broadband Forum. “When the Broadband Forum started there were less than a million broadband connections and now there are more than 750 million. This is an extraordinary achievement and one that would not be possible without the hard work and commitment of our members, like Les, on our various projects.”

Broadband Forum's TR-221 Addresses MPLS for Mobile Backhaul

The Broadband Forum published its new "Technical Specification for MPLS in Mobile Backhaul Networks" (TR-221), which is set to become a key enabler for mobile operators as they migrate from traditional TDM networks to packet-based transport technologies and from 2G/3G to 4G and LTE services. TR-221 provides a key resource to the industry as it gears up for explosive growth in IP traffic driven by new and enhanced devices on the mobile market, from tablets and smartphones to multifunction gaming consoles.


TR-221 focuses on the applications of MPLS technology in a range of services that may be used to transport wireless traffic in the access and aggregation networks, including IP, TDM, ATM and Ethernet. It defines the global requirements of MPLS technology in these networks in respect of encapsulation, signalling and routing, QoS, OAM, resiliency, security and synchronization. It also covers expected services over the backhaul network that include voice, multimedia services, data traffic, and multicast traffic such as multimedia broadcast and multicast services (MBMS). Adherence to these requirements will create global standards for MPLS oriented equipment, establishing more network interoperability, speeding deployments and lowering the overall costs of the backhaul network.


Defining a range of reference architectures for MPLS based Mobile Backhaul networks; TR-221 includes specifications for the various transport scenarios applicable to all mobile networks (e.g. 2G, 3G and LTE). It also specifies the equipment requirements for the control, user and management planes to provide unified and consistent end-to-end transport services for mobile backhaul.


Robin Mersh, CEO of the Broadband Forum, said: "TR-221 is a critical part of establishing multi-vendor interoperability in converged MPLS based backhaul networks. As mobile operators look to preserve their investment in traditional TDM and ATM networks whilst developing their 4G/LTE architectures, TR-221 will enable them to integrate new packet-based MPLS technologies into their established networks. Operators will be able to evolve their networks to be faster and more efficient to meet the increasing multimedia needs of the mobile user, whilst preserving a lower cost per bit in the backhaul network."http://www.broadband-forum.org
