NTAC Peering and Routing
5/18/10
In attendance: Jeff Bartig, PJ Clayton, John Hernandez, John Hess, M=
arla Meehl, Darrell newcomb, Chris Robb, Linda Roos, Pete Siemsen, David Si=
nn, Shannon Spurling, Scott Taylor, Kenny Welshons
Agenda
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 pee=
ring point in Dallas with LEARN. Further, he mentioned that there hav=
e been an increased number of route announcements from peers. An anno=
uncement of 40,000 routes will be made next week (May 24). Chris Robb made =
an announcement regarding these additional routes to connectors last week a=
nd 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 smoot=
h graph is the CPS link.
2. Update on CPS/TR consolidation implementation
Meetings regarding the consolidation have continued and a fair amount of p=
rogress has been made. Michael lLambert talked about the BGP communit=
y 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 e=
xpects 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 ne=
twork. There has been preparation on the operational side for call ce=
nter activities with a target deadline in June to cut over call center duti=
es 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 servic=
e 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 s=
uggestion to aim for 1500 byte during the transition and to consider jumbo =
frames later. Jeff mentioned that we might consider, as the new backb=
one is build out, there may be an opportunity to change the MTU to allow la=
rger frames with commercial peers in the future. Chris suggested writ=
ing a document describing this notion and sending it to the list. LON=
I would be willing to use larger MTUs with the peering service, WISCnet wou=
ld 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 t=
hat LONI is pushing their campuses to jumbo frames. Chris again sugge=
sted sending a note to the entire NTAC list with the pros and cons.
