Network Reliability and Interoperability Council VII

Focus Group 4 Charter

“The Council shall present recommendations to increase the deployment of high-speed residential Internet access service. The Council shall include Best Practices and service features that are, and will be, technology-neutral. The Council’s recommendations shall be prepared in such a way as: (1) to ensure service compatibility; (2) to facilitate application innovation; and (3) to improve the security, reliability and interoperability of both residential user systems and service provider systems. ”

Scope

• NRIC VII Focus Group 4 will identify and develop reference

model architectures illustrating all current generally available alternatives to provision high speed residential Internet access service.

• These reference models will be the most commonly known

methods for high-speed residential Internet Access deployment.

• The reference models, reflecting today’s existing environment,

are to be segmented by the type of infrastructure deployed

• These reference models will depict only those components of the

architecture required to provide high-speed residential Internet access service.

• While some of the reference models may be geographically

bounded, others will not be geographically bounded.

Methodology

• Reviewed the work of the NRIC VI FG on

Broadband and agreed to use it as a baseline and move forward from there with our new charter.

• Developed the definition of Residential Internet

Access

• Developed the Master Reference Model and defined

the demarcation points for this effort to be on the network side of the connection to the customer and at the connection point to the Internet

• Subgroups developed models of the architectures.

Residential Internet Access

• The term Residential Internet Access encompasses the many

different commercially available ways for Residential Consumers to access the Internet.

• The use of this term in the context of this deliverable is not

application specific.

• Residential Internet Access is considered to be a pathway from the

subscriber to the public Internet.

• Broadband technology should be viewed in terms of having

sufficient bandwidth to provide satisfactory performance while accommodating a wider range of customers, applications and technological requirements.

• It is viewed to be always-available access technology so long as the

user’s Internet device is turned on, and requires no additional user activity to function.

• It has sufficient bandwidth to support multiple applications

simultaneously.

• The area of concentration for this focus group is to offer

recommendations to further advance the domestic use of broadband technology for Residential Internet Access.

Next Steps

• Based on these models, the Focus Group has

already begun the next effort to identify Best Practices that facilitate the deployment of a high speed residential Internet access service

• architecture. The deliverable is due on June 24,

2005

• A sub group has determined the status of our

existing broadband Best Practices. We have begun to set the path for the development of our new Best Practices.
