Issues of FG4

• The Broadband Charter was ostensibly Too Broad
  in the beginning, and specifically covered the
  scope of technical standards concerning broadband
  deployment.
• Changes have occurred in the regulatory
  landscape, the marketplace, and in the Focus
  Group 4 membership.
  

5
Original Charter

• The Committee will make recommendations
  concerning the need for technical standards to
  ensure the compatibility and deployment of
  broadband technologies and services, and will
  evaluate the need for improvements in the
  reliability of broadband technologies and
  services.

6
Modified Charter

• The Committee will make recommendations to
  ensure the compatibility and deployment of
  broadband technologies and services, and will
  evaluate the need for improvements in the
  reliability of broadband technologies and
  services.

7
Other Sources of Change

• The marketplace has evolved with the advent of
  new broadband deployments (Wi-Fi, powerlines).
  
• There have been policy and regulatory changes
  impacting the broadband marketplace.
  
• Several original members have been absorbed,
  merged, retired, or have gone out of business.
  

8
What is Broadband?

• Since the formation of the FG4, multiple
  organizations have announced new definitions of
  broadband.
  
• Many groups have tried (and continue to
  attempt) to emphasize speed metrics as the
  primary description of what is broadband.

9
FG4 Sub-Teams

• In order to accomplish our tasks, the FG4
  group broke into subgroups each concerning
  themselves with specific areas.
  

• Concepts of Broadband
• Traffic Management
• Service Transparency
• Access / Broadband Onramp

10
Concepts of Broadband Sub-Team

• Team Originally Chartered To Develop Working
  Definition Of Broadband For FG4 Report Usage
  
• Research of Existing Documentation
• Initial Team Effort Attempted Defining
  Broadband Exclusive Of Transmission Speeds
  
• Review And Approved By Sub-team
• Initial Definition Direction Modified After
  Larger FG4 Review and FCC Input
  
• Revised Explanation of Broadband Concept
  Developed In Terms Of Satisfactory User
  Perception For Application Needs
  
• Review and General Acceptance By Larger FG4 Team
  
  
• Requires Another Group Session for Editing
  (9/12/03)
  
• Requires Final Review/Recommendation/Acceptance
  by the Larger FG4 Team (post 9/12/03)
  

11
Traffic Management Sub-Team

• Issue
• Traffic Loads Vary at Broadband Interfaces
• User Network Interface Multiple and
  time-varying applications
  
• Network Network Interface Varying number of
  users and varying types of user applications
  
• Peak Traffic Loads Could Exceed Service
  Agreements and Cause Network Congestion that
  Degrades the Quality of Service to Others (Packet
  Delay Packet Loss)
• Description of Solutions to Promote Broadband
  Compatibility and Deployment
  
• Engineer Link and Network Capacities to Handle
  Some Excess Peak Traffic
  
• Design Equipment (e.g Buffers) to Accommodate
  Time-Varying Traffic Loads Gracefully
  
• Quality of Service Protocols that support
  Multiple Classes of Services with Different QoS
  Requirements
  
• Traffic Management Mechanisms Committed
  Service Rates Traffic Shaping and Policing
  Marked and Dropped Packets
  
• Draft Recommendations to Promote Broadband
  Compatibility and Deployment
  
• Consider Use of Technical Solutions (Suppliers
  and Service Providers)
  
• Participate in Standards Development
• Make available Traffic Policy Information to End
  Users to Facilitate Their Planning and Use of
  Broadband (Service Providers)

12
Service Transparency Sub-Team

• Identify potential disrupters of end-to-end
  service transparency and propose recommendations
  for minimizing problems
  
• Macro Ideas
• Accelerate transition to IPv6 to mitigate NAT and
  Firewall issues
  
• Service Provider Considerations (recommendation
  potentials)
  
• Internally establish controls to administer
  network policy associated with blocking and
  filtering
  
• Make available meaningful information about
  blocking and filtering policies
  
• Make available meaningful information about
  expected performance with respect to upstream and
  downstream through-put and any limitations of the
  service (i.e., throughput caps, etc.)

13
Access/Onramp Sub-team

• Team Originally Chartered To Develop Working
  Description of Access/Onramp availability of
  Broadband to subscribers in the US.
  
• Descriptions of drivers that determine end user
  broadband availability.
  
• Explore broadband technology trends looking
  toward future potential Broadband access
  solutions.
  
• Look to future architectural issues concerning
  newer technologies for Broadband access.
  
• Address current Broadband distribution and
  availability.

14
