NTAC Peering Working Group

[Chris Robb <>]

All:

One of the action items out of the February architecture discussion was to look at how we logically organize the Layer3 network on top the Layer2 equipment. There was some good back and forth discussion in the later calls about whether or not to implement a full mesh of IP router-to-router VLANs over the IP network, how to prioritize the different interconnect technologies, and how to load share traffic on the L3-L2 interconnects. 

We've pulled together a document that provides a starting point for discussion. We've thought through a few of the scenarios and have attempted to highlight the advantages and gotchas to some of the approaches. This is not a complete view of everything and is meant to spur discussion. 

We purposefully don't make a recommendation here. I'm interested in hearing about options and permutations we need to add to this document and other feedback on the pros and cons. 

I suggest we spend this next week iterating on this via e-mail and try to get together on a call the week of June 3rd to discuss. I've created a doodle pool with some potential times to chat. Hopefully we can find a time that works for a large number of interested parties.

Given that we have equipment being installed in the next week to put most of this in place, we'd like to start thinking about beginning to stand pieces of this up in the mid-June timeframe. 

Thanks. Looking forward to the conversation!
