    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.

    Works in Progress:
    SD-357: Combined 3GPP and BBF Functions

    Network Enhanced Residential Gateway
    This Working Text specifies the Network Enhanced Residential Gateway (NERG) architecture. This architecture consists in shifting some of the functionalities of a residential gateway to the operator's network, for enabling network based features. The aim is to facilitate the deployment, maintenance and evolution of both existing and new capabilities without adding complexity to the RG and/or the home network.
    Public WiFi Access
    Since the introduction of mobile devices that include Wi-Fi, there has been an increasing interest in improving Broadband Forum's multi-service broadband architecture to incorporate the public Wi-Fi access. WT-321 addresses use cases, physical and logical architecture and functional and/or nodal requirements for public Wi-Fi access capabilities that are used nomadically as part of a broadband network. WT-321 builds on the work done in IETF's CAPWAP architecture and comes up with a new public Wi-Fi access network architecture.
    Virtual Business Gateway
    This Working Text specifies architecture and requirements for the virtual business gateway. The virtual business gateway architecture describes the migration of functionalities running on a business gateway to the network service provider's infrastructure for enabling network-based features and services. Such migration is expected to simplify the deployment and management of the network and business services.
    The purpose of this Working Text is to specify the virtual business gateway architecture as well as deployment scenarios. Such architecture would target different business premises sizes, e.g., small and medium enterprises (SMEs), campus, as well as single office and home offices (SOHO).
    Radius Attributes Catalog

    The purpose of this Working Text is to consolidate the existing BBF AAA work into a single concise catalog or information model for authentication, authorization and accounting functions within a BBF network.

    This Working Text will also provide the opportunity to standardize common vendor specific implementations into standard attributes.
    Migrating to NFV in the context of WT-178
    Building on TR-101 and TR-178, WT-345 documents a set of architectures for broadband multi-service network, addressing infrastructures, topologies and deployment scenarios for Multi-Service Broadband Network Gateway (MS-BNG) with hierarchical instances realized as Virtualized Network Functions (VNF).

    Starting from such architectural models WT-345 defines the specific requirements necessary to support the addressed infrastructures, topologies and deployment scenarios, in order to fulfill the business requirements defined in TR-144. The main changes introduced in the WT-345 architectures compared to the TR-101 and TR-178 models are:
  • - Implications of scale out
  • - OAM and other Operational aspects
  • - Traffic management and QoS
  • WT-348
    Hybrid Access
    Bonding fixed broadband access and 3GPP access networks can enable service providers to offer higher throughput and better Wide Area Network (WAN) reliability solutions to their customers. In this bonding scenario, advanced traffic distribution mechanisms are needed. This Working Text defines the architectural requirements and solutions for the connections of premises by means of both fixed broadband (DSL, GPON, P2P Fiber) and 3GPP WAN interfaces.
    A Framework for Virtualization
    The purpose of this working text is to establish a framework to permit the Broadband Forum to effectively reference and specify systems such that the deployment of NFV (as defined by the ETSI NFV ISG) in Broadband Forum specified networks is facilitated.

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

    Works in Progress:
  • IL-280: WT-280 Issues List
  • IL-301: WT-301 Issues List

    ITU-T PON in the context of TR-178
    WT-280 focuses on GPON systems in an unbundled services environment that addresses requirements not covered by TR-156. TR-156 and WT-247 address basic L2 GPON systems. There are "more complex" types of ONT and Service Providers have more complex requirements that need a reference in BBF GPON framework. ITU standards already cover these more complex functionalities from an OMCI point of view. What is missing are the architectural/functional requirements.
    Fiber to the
    Distribution point
    This Working Text defines a new node type, for use within the access network at the subscriber side fiber termination. This node provides a Distribution Point (DP) that supports one or more high-speed copper drops to individual subscribers. All aspects of the introduction of this node type into the network are considered and requirements are identified for the DP Unit (DPU) and all affected access section nodes.
    The requirements contained within this Working Text are defined within the framework of both the TR-101 and TR-144/145 architectures. The TR-101 architecture is required to support near term residential deployments while the TR-144/145 architecture is required for the evolution to a multi-service edge network that supports residential, business and wholesale deployments.
    Architecture & Technical Requirements for PON-based Mobile Backhaul networks
    In development.

    Management Architecture and Requirements for FttDP
    The architecture and requirements for FttDP are the subject of WT-301. Although there are similarities of FttDP with other types of concatenated fibre and copper access systems, e.g. FttCab, GPON ONUs there are also some very different aspects, e.g. Reverse Power Feeding, small node size, new copper technology (, low power consumption, etc. There are also some functions in a FttDP node that do not exist in other systems. These differences impact the management requirements for the FttDP node. This Working Text addresses these impacts; it specifies the management architecture and requirements and the management models for the component parts of the FttDP architecture.
    DSL Data Sharing
    This Working Text explores issues related to DSL data sharing and includes a standardized data model for DSL data sharing.
    YANG Modules for FTTdp Management
    This Working Text defines YANG data models for the management interfaces to support FTTdp. These models are to enable interoperability for FTTdp management.
    Alternate Management Path for Broadband
    This document describes a new method of managing broadband lines using an alternate data channel or path and particularly for diagnosing disconnections. For example, a smartphone can connect to a broadband modem or RG and access diagnostics data to troubleshoot a disconnected broadband line. This connection would be between the LAN side of the RG and the smartphone. The smartphone would then use an app or other system to relay this connection through the 3G/4G network back to a management server. Similarly, a neighboring WiFi connection or another data connection could be used instead of the smartphone relay. Re-configuration of the broadband modem or home network may also be performed over the alternate management path.

  • SDN in Broadband Networks Working Area

    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.

    Works in Progress:  
    Support for SDN in Access Network Nodes
    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.

    Service Innovation & Market Requirements

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