The Broadband Forum(formerly the DSL Forum)

Chief Operating Officer

July 14-17, 2008

• Work has evolved-
• Moving from ADSL transport to addressing all DSL options
• Adding access-agnostic remote management specifications
• Now we are adding fiber specifications into our broadband solutions
• Over the years, our focus has changed from simple connectivity to supporting dynamic IP-centric services and CPE remote management

• As the technology matured, so did the work of the Forum
• Yet as our scope grew and evolved, our identity stayed the same and today it is clear that the name DSL Forum no longer represents all we do
• It was time for change…

• The Broadband Forum mission is to develop the full potential of broadband. Focused on application based solutions, our standards empower providers to achieve more with broadband deployment and management.

• Work will continue
• DSL related work will continue as strong as ever!
• Fiber related architecture and home network support will expand
• Additional work will launch addressing IPTV, including white papers on Installation Best Practices
• Quality of Experience (QoE) takes center stage with new work, and service provider best practice education
• Commitment to IPv6 adherence in all specifications
• Fixed Mobile Convergence related work is kicking off
• Energy efficiency becomes a more visible consideration in all we do

• BroadbandSuite Release 1.0

Internet access via ADSL or SHDSL over a QoS-enabled ATM architecture. Supports VoIP transport & VoDSL

• BroadbandSuite Release 2.0

Triple-play access via ADSL2plus (or ADSL) over a QoS-enabled Ethernet architecture. Full support for multicast to enable IPTV streaming

• Coming in late 2008!Release 3.0

Triple-play access augmented via VDSL2, GPON or bonded DSL over a QoS-enabled Ethernet architecture. Full support for multicast to enable IPTV streaming. Integrated remote management of Set-Top Box & attached storage devices

Builds on past releases

Triple Play / IPTV focused work

• TR-126 documented the requirements for IPTV (both standard definition and high-definition) 
• This work was extensively liaised to standards bodies like ATIS and ITU who used it to inform much of their own work in this area. 
• TR-101 provided:  
• Blueprint for how to build a multiservice/triple-play broadband network and includes the functional requirements of all the key network elements (Residential Gatey/DSL router, Access Node/DSLAM, aggregation network and Broadband Network Gateway (BNG).  
• Functional requirements to cover the capabilities needed to deliver IPTV with multicast and QoS (see also TR-92 for more background on BNG QoS requirements such as hierarchical scheduling).
• TR-101 architecture is currently being extended to encompass GPON access via WT-156. 

• Given a good architecture like TR-101 and good design implementation and capacity management then the delivery of IPTV over the core and aggregation networks should be well assured.  
• Then, the most likely root cause for IPTV QoE problems experienced by an end-user is likely to be the DSL line (copper) or home network.  
• Hence the Broadband Forum has put a huge amount of effort into the performance requirements and associated testing of the DSL layer transmission systems
• TR-100 for ADSL2plus and
• WT-114/WT 115 for VDSL2

NEW!TR-140: Storage Data Model

• More recent work is addressing QoS in home networks(in conjunction with HGI – Home Gateway Initiative).
• Extend the geographic coverage of IPTV by extolling the virtues of various transmission approaches that can give improvements (PD-180).  
• Specific recommendations for DSLAM profiles to be used to deliver IPTV over ADSL2plus (WT-176). 
• Service providers are seeking to improve their business case for IPTV over DSL by enabling end-users to self-install the equipment.  
• It is important that this is done correctly to ensure the appropriate IPTV QoE is not compromised by such an installation.
• Hence we are producing an IPTV Installation best practice guidelines in this area (PD-179).

TR-135

• The Future of gateway/modem requirements
• Broadband Forum will continue to add additional interface feature modules to maintain current with RG market demands
• Add new features or network devices as service deployments require
• Add new WAN/LAN interfaces as they are introduced to market (e.g. Bluetooth, GPON, WiMAX, etc.)
• Full QoS in BroadbandHome
• Refine Home Network Reference Model
• Extend Broadband Forum Network Requirements (TR-059) to the Home
• Adopt/Leverage QoS Specifications defined by other standards groups such as UPnP, DLNA, IETF, HGI
• Continue to align with the industry
• In regards to IPTV / Triple Play specifically, coordinate closely with ITU-T (SG9/SG11/SG12/SG13/SG15/SG16), ATIS IIF, UPnP Forum and DLNA to ensure we are closing any technical gaps within our remit and we are not duplicating any efforts

Strategic objectives overview

• Expand and address physical layer options (ADSL2plus, VDSL2, and fiber) for greater performance
• Continue to address key IPTV functions, expedite STB management, and resolve performance issues
• Continue to promote the position of the TR-069 family of CPE remote management specifications
• Act as the wireline advocate in FMC requirements - this is becoming a bigger focus as this business develops
• Address IPv6 considerations in all our work - architecture, home and policy control specifications currently being updated
• Incorporate energy efficiency considerations into our specifications - network and customer premises are a priority
• Continue to liaise and coordinate with the wider industry - SDO’s, fora and consortia

• Holistic view of the Broadband ecosystem
• Measurement methods
• Tools (such as checklists, footprint calculator etc.)
• Improved technologies and architectures
• Low Power ADSL2+, VDSL2 and PON - Test requirements for L0, L1, L2
• Always available not always on
• Information and Presence based power
• End-end approach
• Convergence of Fixed and Mobile Broadband
• Remote device
• Management
• Networking
• Policy
