 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

It’s 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same and today it is clear that the name DSL Forum no longer
represents all we do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…
3
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.
4
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

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.
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.
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 Home
Work 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 selfinstall 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
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 SDO’s, fora and consortia
19
Energy Efficiency aims
 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
