Technical Work in Progress

There is a tremendous amount of technical work going on in the Broadband Forum, and below is a brief overview of the current initiatives. As all Working Texts are works-in-progress, they are not available to the public. Once the work progresses and is approved by the Broadband Forum membership, the Working Text converts to a public Technical Report. We provide the abstracts below to simply give you a sense of the work.

Working Groups

DESIGN
ARCHITECTURE & TRANSPORT

Mission Statement:
To oversee and coordinate all architecture and transport related technical work within the Forum.

Works in Progress:
WT# TITLEABSTRACT
WT-134
Policy Control Framework
 An architectural framework for policy control of DSL access networks.
WT-145
Multi-service Broadband Network Funtional Modules and Architecture
This working text provides reference architectures for multi-service broadband networks, defines high level network requirements, and specifies functional modules to meet those networks requirements. This WT also provides guidance to distribute these functional modules onto multi-service broadband network elements. Detailed broadband network nodal requirements will be specified in further working texts e.g. WT-178.
WT-146
Internet Protocol (IP) Sessions
Numerous members of the service provider community have recently shown significant interest in migrating from a pure PPP access environment towards one with IP subscriber sessions for delivery of all IP services such as voice, video and high speed internet over a common data transport protocol. A number of factors are driving the interest for such a transition. For one, operators see a potential in simplifying their operational/user support complexity, as well as harmonizing network element functionality around the IP protocol. Operators running multiple access networks also view IP service delivery as the key lowest common denominator towards delivering common services in a converged network, where the PPP would be specific only to PSTN dial and DSL access segments. Given these motivations, the ability to transition to an IP user service delivery model suggests the adoption of a subscriber IP session construct in order to allow the service provider to handle each subscriber according to their individual service contract. This document provides the description of the construct and relevant IP node requirements.
WT-147
Layer 2 Control
 This document degines a Layer 2 Control Mechanism between a BNG and an Access Node in a multi-service architecture in order to perform QoS-related, service-related and subscriber-related operations.
WT-156
Using GPON Access in the Context of TR-101 This document provides architectural and network element requirements to allow the use of GPON access nodes in the TR-101 access architecture. TR-101 provides triple play application support in an architecture that migrates from ATM access to Ethernet access technology.
WT-167
PON Fed DSLAMs
This working text provides architectural and network element requirements to allow the use of a GPON ONU as an access node defined in TR-101. TR-101 provides triple play application support in an architecture that migrates from ATM access to Ethernet access technology.
WT-177
Migration to IPv6 in the context of TR-101
This Working Text presents a DSL Forum access network architecture that enables operators to migrate to IPv6. It is built upon DSL Forum TR-101, which describes a popular and successful DSL Forum architecture for supporting Ethernet-based DSL aggregation. This document extends the TR-101 architecture to enable IPv6-based services and applications. In doing so, it presents the requirements for protocol interworking, multicast and security for the network elements that are part the TR-101 architecture.

    WT-159
    Management Framework for xDSL Bonding
    		 This Broadband Forum Technical Report provides the management framework for xDSL bonding technology per ITU-T recommendations G.998.1 (ATM-based multi-pair bonding), G.998.2 (Ethernet-based multi-pair bonding) and G.998.3 (Multi-pair bonding using time-division inverse multiplexing). The document defines the required managed objects. The document is protocol independent, which means it does not refer to any particular management protocol between the Element Management System (EMS) and the Network Element (NE).
    WT-160
    IPTV Performance Monitoring and Diagnostics
    		 The purpose of this Working Text (WT) is to address the requirements for performace monitoring and diagnostics for IPTV services provided over next generation multi-service broadband access networks. It considers what capabilities exsist to meet the requirements, identifies gaps, and defines new capabilities where necessary.
    WT-165
    Vector Profiles
    		 This WT addresses the need for greater flexibility in setting DSL profiles by defining a vector of profiles. The DSL configuration parameters are divided into N independent sets of parameters. Each parameter set is used to define profiles. The profiles are referenced from a vector of N numbers, each number identifying a profile. This allows a large number of profiles to be used without having to store huge quantities of profile data.
