    Broadband Access Service Attributes and Performance Metrics
    This project will specify a test architecture and framework to enable standards-based testing and reporting of broadband performance. It will include: definitions of network segments under test; tests and methodologies appropriate for each segment; recommended testing intervals for network performance characterization; support of tests that span multiple operator networks; a standard method for quantifying and comparing access services; and tools to enable communication of service attributes and performance requirements between service providers, application providers and customers.
    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
    In development.
    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.

    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.
    Multi-wavelength PON Inter-Channel-Termination Protocol (ICTP) Specification
    The purpose of this Working Text is to specify a protocol that is executed between the OLT Channel Terminations and, based on the architecture and functional descriptions outlined in ITU-T Recommendation G.989.3, enables wavelength channel management within an NG-PON2 system.

    G-PON and XG-PON1 Management
    This Broadband Forum Working Text provides a management model to meet the requirements in TR-156 and related ITU-T recommendations. It derives from TR-156 the relevant managed objects and arranges them in the form of logical sets, called managed entities. This working text then defines the MIB of the OLT and then facilitate the integration of new technologies in operators IS.
    Fiber Infrastructure Management System: Architecture and Requirements
    Broadband Forum Technical Reports address an Ethernet-based architecture optimized for multi-service Passive Optical Network (PON) deployments focused on both residential and business customers. WT-311 addresses architecture and functional requirements of emerging intelligent Optical Distribution Network (ODN) systems that form the physical plant layer of PONs. These requirements cover system architecture, layer functional requirements, and interfaces and/or data models for interoperability with service provider operations support systems (OSS). The specifications in WT-311 apply to PON systems that are specified both in ITU-T G-Series Recommendations and IEEE 802-Series standards.
    GPON Access Node Management Requirements
    It is assumed that at an Access Node in the network there is equipment that implements the functionality defined in TR-101 and TR-156 with the access technology functionality defined in the G.984 series of Recommendations. This Working Text contains the Service Providers' requirements for the management of this equipment in order to deliver service activation, fault diagnosis and performance monitoring. The starting point is general and specific operational process requirements. Then use cases are provided to support these requirements. The use cases are combined where appropriate and then used to generate the management requirements. The management requirements detail specific management parameters or entities that are required to be available at the NMS/EMS interface and the necessary supporting operations.
    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 Data Models for & VDSL
    In Development.
    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.

    Works in Progress:

  • IL-340: SD-340 Issues List

    High Level Requirements and Framework for SDN in Telecommunication Broadband Networks
    Software Defined Networking (SDN) may create a long-term evolution within telecommunication broadband networks. By incrementally introducing SDN concepts, without rebuilding the whole network, operators have the opportunity to migrate to SDN while protecting existing investment. This project will examine some deployment scenarios including where only some of the network equipments would support SDN functionalities, as well as possibility of supporting SDN capabilities by upgrading software only.
    Per the mission of SIMR WG, SD-313 will include recommendations for follow-on Broadband Forum work regarding SDN.
    Flexible Service Chaining

    In order to support business and residential, fixed and mobile, wholesale and retail markets, TR-144 described various requirements including the need for network interconnection standards for broadband access, QoS support, Bandwidth on demand, increased overall bandwidth, higher network reliability and availability.

    New ways of defining services are required to keep up with market needs, seeking more flexibility in service deployment, faster service feature delivery, increased automation, elastic service bursting, etc.

    Service chaining allows complex services to be created out of simpler service-enabling elements through composition, e.g. stringing service points together while possibly constraining the corresponding data path.

    The output of this project will provide guidance to BBF's Technical and Marketing Committees on the work needed to bring flexible service chaining concepts to the level of detail necessary to define broadband network element requirements for implementation. This Study Document will also provide a reference for other service chaining standards organizations.

    Stage 1 for introduction of Network Function Virtualization in MSBN
    In the form of an annotated slide stack, SD-340 presents a high level study on the introduction of NFV into MSBN, including business scenarios and use cases which will impact existing network architecture. Major impacts when the NFV framework is mapped to MSBN are also examined. In addition, it gives high level requirements and recommendations to the End to End Architecture Working Group on next steps.
    Stage 1 Analysis of Fixed Access Network Sharing (FANS)
    The purpose of SD-351 "Stage 1 Analysis of Fixed Access Network sharing" is to investigate the technical aspects associated with fixed access network sharing (FANS) by leveraging network virtualization and potentially other technologies focusing on greenfield but not excluding brownfield deployment scenarios.
