Our work stays aligned with industry market
requirements

• 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

3
Its all about Evolution

• 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  name DSL Forum no longer represents all we do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

4
Becoming The Broadband Forum

• 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.

5
How will this change us?

• 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

6

Improving Access/Architecture Requirements

• 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-p
  lay 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. 

12
Performance is key

• 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

Quality Standards for the HomeWork in development

• 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).

Next Steps for our work in Triple Play

• 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
19
Broadband Forum Strategic Objectives

• 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 - SDOs, fora and consortia

20
