3Charter
The purpose of Focus Group 4 is to provide
recommendations to the Council that, when
implemented, will facilitate and assure
interoperability of public data networks. The
duties of the Focus Group 4 will be to prepare
studies, reports, and recommendations for
assuring data network interoperability within the
parameters set forth in the NRIC V Charter. Focus
Group 4 will determine what levels of
interoperability are needed. Focus Group 4 will
also monitor future developments to ensure that
interoperability is not at risk. Focus Group 4
will make recommendations with respect to
interoperability issues that may arise from
convergence and digital packet networks. Focus
Group 4 may also make recommendations with
respect to such additional interoperability
issues as the Commission may specify.

- Consensus on short term tasks
- Carrier Interconnection
- Statement encouraging publication of peering
guidelines - Outline and progress on interconnection paper
- Cooperation with 2.A2
- Testing Discussions
6Carrier Interconnection / Peering Issue
- We have had discussions on SP interconnection and
peering at all three meetings - Consensus to publish a short statement
encouraging service providers to publish their
criteria for peering - Goal is to foster transparency
- Cover letter and statement are attached
- Consensus to produce longer paper discussing
interconnection issue - Outline is attached
7- To James Crowe
- The NRIC V Interoperability Focus Group (Focus
Group 4) - has developed a consensus
recommendation that it would like to place before
the Network Reliability and Interoperability
Council for consideration at its next meeting on
June 26. The recommendation and statement,
which are attached, request that the Council
encourage Internet service providers, and
especially the large "backbone" Internet
providers that comprise the core of the modern
Internet, to consider, consistent with their
business practices, publication of their criteria
for peering. - More specifically, Focus Group 4 believes that
this action will promote transparency and
facilitate interoperability, especially with
respect to new Internet service providers.
Accordingly, we respectfully request that you
place this recommendation before the Council at
its next meeting and, if it is adopted, that the
Council publish this recommendation. - Sincerely, Scott Bradner, Ross Callon
(co-chairs) -
8- NRIC Encourages Publication of Peering Criteria
- to Promote Transparency
-
- Because no one provider directly connects a
plurality of sites within the Internet,
interconnection between providers is necessary.
The form of interconnection known as "peering",
in which Internet providers agree to exchange
traffic for their respective customers but not
for third parties, is commonly deployed and
widely accepted. - Internet providers do not and can not peer with
all other Internet providers. They make conscious
decisions as to which providers they will peer
with, and under what business terms. In the
United States, the decision to peer, or to
decline to peer, is driven by market forces,
rather than by government regulation. Moreover,
there is no legal obligation to disclose these
decisions or these terms. -
- (continued...)
9- Over the past year, several of the largest
Internet providers in the United States have
voluntarily chosen to openly publish the basis on
which they decide with whom they will peer. In
the opinion of NRIC V, this has been a positive
development, both for U.S. industry and for the
global Internet community. It has significantly
enhanced transparency of process in the industry.
- NRIC V encourages other Internet providers, and
especially the large "backbone" Internet
providers that comprise the core of the modern
Internet, to consider, consistent with their
business practices, publication of their criteria
for peering.
10White Paper on S.P. Interconnection
- White paper on Service Provider Interconnection
- Discusses issue
- Provide background for discussions of
interconnection issues - Progress to date
- Draft outline sent to focus group prior to our
last meeting - Outline discussed and edited in detail at FG4
meeting - We have some draft text
- Multiple participants have volunteered to produce
text - Next step
- Assemble draft text prior to next meeting
- Discuss and edit in detail

12Cooperation with 2.A2
- Focus Group 2, working group 2.A2, has produced
best practices for reliability in data networks - Karl Rauscher gave a general overview to FG4
3/2001 - FG4 went through BPs one-by-one at meeting 5/2001
- Results have been written up, distributed to FG4,
and updated based on comments received - Next step Relay to 2.A2
13Testing
- FG4 has had two discussions on testing
- Presentation by D.Currie, R.Parker, and
R.Neumann, 3/2001 - General discussion, 5/2001
- Strong agreement on the importance of testing
- Agreement
- There are many valid forms of testing
- There are many organizations involved in testing
- (including vendors and service providers)
- FG4 is reluctant to endorse any particular test
group - FG4 will produce a short draft summarizing
conclusions to date - For discussion at next FG4 meeting
14Future Meeting Schedule
- July 24 in San Jose, CA (hosted by Cisco)
- Future meeting schedule
- September, 2001 in Boston
- Probably November or early December in DC
- Dates need to be set ASAP
15Recommendations / Next Steps
- Continue to encourage participation
- Publish short statement on peering criteria
- Continue progress on white paper
- Plan to have the paper by October
- Is likely to be augmented over time
- Coordinate with other FGs as appropriate
