Dear Layer 3 Community Group,
First, thanks to Michael for his thoughtful consideration of the report and
for his comments below. He has a clear, concise articulation of the issue and
a suggested solution.
As we have about a week before the report needs to be presented to the
NAOPpag (on April 27 at the Global Summit), I request a two-step process:
1. By COB on Monday, April 20, send any comments to add to Michael's
remarks. If you don't send comments, we will assume that Michael's suggested
direction is fine with you.
2. On Tuesday, April 21, we will update the report based on Michael's
remarks and send the updated report to the group for endorsement with a
requested response by COB Thursday, April 23. We are asking that everyone in
the group respond so that we understand the perspective of the entire group.
Thank you again for your participation in this process. We appreciate it. Let
me know what questions you have.

> the timeframe. (In Internet parlance, "near future" could mean
> something like 3 months.)
> The major comment is this: The report appears to be written by the
> 3 Community Group, directing the I2 engineering staff to do a bunch of
> detailed things regarding network consolidation. See, for example,
> the title, "Layer3 Community Group Report: Consolidating TR-CPS and R&E."
> The document then starts off with "This document is meant to outline
> the steps and policies Internet2 will implement in response to the
> Future Peering Committee's...."
> The key word there is "will." Is this will in the sense of "here's

> I still think that is the purpose here, and I think we should better
> reflect that this report originated among I2/IU technical staff and is

> their discretion. For example, we tend to assume consolidation leads
> to cost savings, but consolidation can also concentrate complexity
> inside a smaller system, which can reduce reliability and actually
> increase costs. It's up to the I2 staff to determine at which point
> the marginal costs of a consolidation activity outweigh the marginal gains.
> If we read the current report as a report of the staff saying "here's
> how we interpret the FPC's recommendation to allow for consolidation,
> does the L3CG concur?" then I think the report is reasonable, with one
