BroadbandHome ™

Mission Statement:
Provide the Broadband industry with technical specifications that define broadband enabled customer devices and ease the deployment and management of broadband services.

Scope:
Maintain and evolve the TR-069 CPE WAN Management Protocol (CWMP). Enhance its capabilities at all stages of the CPE remote management lifecycle: Auto-configuration, service provisioning, firmware management, diagnostics, fault and performance monitoring. Develop and specify new CPE device models (including XML schema) to broaden the range of devices for which TR-069 can be used. Extend home networking device specifications for emerging network interfaces and protocols. Use of remote CPE management to facilitate improved energy efficiency.

End to End Architecture

Mission Statement:
Responsible for the end to end architecture and associated nodal requirements with respect to the native service layer and above.

Scope:
Access architecture encompassing interface definitions and nodal functional requirements from Residential Gateway (RG) through Access Node, aggregation network and Broadband Network Gateway (BNG) to peering interfaces with network and application service providers. The focus is end-to-end service delivery across this domain encompassing equipment requirements to support capabilities such as QoS and multicast functionality. The WG also encompasses policy and control of the key network elements and protocol interworking requirements. All broadband wireline access technologies are within scope of this access architecture work (e.g. DSL, G-PON, point-to-point fibre). Wireless broadband access technologies will be addressed via liaison with the appropriate standards body (e.g. WiMax Forum, 3GPP etc.). Consideration is also given to the relative energy efficiency aspects of access architectures.

End to End Architecture

Some end to end architecture issues (e.g. IPv6, QoS, security etc.) may require a joint session between the End to End Architecture WG and one or more other WGs, which is dynamically arranged depending on the topic to be addressed. Hence there may be multiple joint WG "End to End Architecture" sessions at each quarterly meeting but involving different WGs along with the End to End Architecture WG depending on the topic.


Fiber Access Network

Mission Statement:
To develop technical specifications related to Optical Access Nodes and associated test plans for conformance and inter-vendors interoperability

Scope:

  • Technology specific considerations for fiber access support of BBF architectures. Definition of interfaces and functional requirements of Access Network transmission systems (OLT, ONT, ...) that use fiber media such as all types of standardized ITU-T and IEEE PONs and point-to-point optical technologies
  • The WG also defines conformance and interoperability test plans for fiber access systems and organizes plugfests on this basis
  • The WG has strong relationships with other organizations like ITU-T, IEEE and FSAN

IP/MPLS & Core

Mission Statement:
Responsible for edge to edge architecture and associated nodal requirements with respect to the infrastructure protocols that support the native service layer.

Scope:
Use of IP/MPLS technology in converged network architecture to address deployment of IP, Ethernet, ATM, and TDM services providing the capability to support multiple applications such as mobile backhaul, video, and Internet access. Includes development of technical specifications to define architecture, requirements, and conformance tests as well as support interoperability events.

Metallic Transmission

Mission Statement:
To develop functional and performance test plans for cross-vendor interoperability of broadband transmission technologies that use metallic media.

Scope:
Broadband transmission systems that use metallic media such as all types of standardized DSL technology operating over twisted copper pairs and standards based home-networking technologies that use copper-pair, power line or coax media. In addition to the test-plans for such systems the WG is also involved in organizing plugfests and developing Energy Efficiency guidelines for these transmission systems. Energy efficiency test plans for network and customer equipment are also covered including guidelines for operating metallic transmission systems in a more efficient manner e.g. use of low power mode.

Operations & Network Management

Mission Statement:
Provide recommendations for operational, network management, and process aspects of broadband access networks.

Scope:
Broadband Access and operational issues including element manger functionality, interfaces and associated MIB definition. Operational best practices for service assurance, trouble-shooting and equipment configuration (e.g. DSL profiles and DSL Quality Management). Consideration is also given to the energy efficiency aspects of network operating paradigms, facilitated by appropriate network management.

Service Innovation & Market Requirements

Mission Statement:
Drive BBF medium-to-long term work directions and requirements in order to lead innovation in broadband.

Scope:
Evaluate market/technology trends with 3 to 10 years horizon. Identify and assess potential enablers and disruptors. Guide BBF with future requirements and directions. Analyze market buzz/hype. Conduct Gap analysis to identify what dots BBF needs to connect. Develop service(s) description, business requirements, use cases. Recommend what role BBF should play and in what areas BBF may develop technical work in the mid and longer terms. Help coordinate strategic external liaison relationships.

The SIMR WG interacts with the Technical Committee and the Marketing Committee.

Work Area

SDN in Broadband Networks

Purpose and Scope:
This work area of the Multi-Service Broadband 2.0 program focuses on introducing Software Defined Networking (SDN) concepts into MSB 2.0. The approach provides operators the opportunity to incrementally introduce SDN techniques of separated data plane and dynamic control plane with centralized control and new degrees of programmability while protecting existing investments. These techniques can improve management efficiency, enhance service flexibility, and provide numerous other benefits associated with SDN. In order to fully realize these benefits, it is important to align SDN functionality with the specific requirements and constraints associated with different elements in MSB 2.0.

The scope of this Work Area (WA) will produce frameworks, requirements, interfaces, best practices, migrations plans, PoC, marketing related deliverables, etc. that leverage SDN where applicable within MSB 2.0. In all respects but particularly with regard to synergies and intersecting requirements that affect SDN and NFV technologies, the Work Area coordinates closely with other BBF activities to ensure consistent architecture, terminology and vision for the MSB 2.0 and other SDOs.

Project Streams:
WT-358 "Requirements for Support of SDN in Access Nodes" has two goals. The first goal is to define the requirements necessary to support SDN-based implementations for Access Nodes including FTTdp. This work is based on use cases identified in SD-313 and existing TRs such as TR-101 and TR-178 developed within BBF. A second goal is to identify gaps in current SDN protocols relative to the requirements identified and to communicate those gaps to the appropriate development organizations.

A second project stream builds on work being completed in Service Innovation & Market Requirements (SIMR) group on "Fixed Access Network Sharing (FANS)" SD-351. The Poject Stream will focus on SDN-enabled FANS, while addressing related requirements identified in the Gaps and Impact Analysis section of SD-351, as well as considering regulatory implications.
