1.    Update from Internet2 on peering
2.    Update on CPS/TR consolidation implementation
3.    Other topics
1.    Update on peering
Darrell Newcomb mentioned that there has been further exploration of a peering point in Dallas with LEARN.  Further, he mentioned that there have been an increased number of route announcements from peers.  An announcement of 40,000 routes will be made next week (May 24). Chris Robb made an announcement regarding these additional routes to connectors last week and an announcement was made to TR this morning. Chris also indicated that a link has been added between Chicago and NY allowing a division of CPS and R&E traffic.  If one looks at the map, the link that shows a smooth graph is the CPS link.
2.    Update on CPS/TR consolidation implementation
Meetings regarding the consolidation have continued and a fair amount of progress has been made.  Michael lLambert talked about the BGP community support on last working group call.  Jeff Ambern has been working on understanding what is operating in the legacy TR and CPS networks and he expects to have a draft document for review by the next NTAC call.  In new network, CPS users will have same communities for pre-pending and black hole routing and fine knob adjustment will be supported in consolidated network.  There has been preparation on the operational side for call center activities with a target deadline in June to cut over call center duties to the Global NOC.  In response to a question regarding the name of the consolidated service, it was indicated that the name of the new service is TR/CPS.  Further preparation is being made to build pseudo wires as well as preparation being made to connect them to the new network.  There was a discussion regarding 1500 or jumbo frames.  There was a suggestion to aim for 1500 byte during the transition and to consider jumbo frames later.  Jeff mentioned that we might consider, as the new backbone is build out, there may be an opportunity to change the MTU to allow larger frames with commercial peers in the future.  Chris suggested writing a document describing this notion and sending it to the list.  LONI would be willing to use larger MTUs with the peering service, WISCnet would also be willing to use larger MTUs.  Most of the peers will be 1500 and may end up fragmenting at the peering routing.  Kenny indicated that LONI is pushing their campuses to jumbo frames.  Chris again suggested sending a note to the entire NTAC list with the pros and cons.
