The last call included a discussion of whether or not IPv6 was done in the core and connectors. Consensus was yes. However much work remains to be done in the Server Farm areas.
The WG was clear that there is a need for more measurements of actual v6 activity at all levels. This could include:
- MRTG graphs that differentiate v4 and v6
- Flow based measurements when more granularity is needed.
- Separate measurements of TR-CPS links.
- Continued look at R&E links
There was also some discussion about whether Multicast was still relevant.
Phil Benchoff also led a discussion about the inclusion of v6 in purchasing requirements.
Peering and Routing:
Darrell gave a brief overview of TR-CPS activity.

Internet2 reports Chris:
Update on the Amazon Issue:
Reports first emerged about 10:00 PM ET on Monday from LONI about traffic to Amazon.
- Internet2 began working with Amazon.
- This process did reveal some areas where work needs to be done.
Amazon had done some maintenance around 3:00 AM Tuesday as is seen on the MRTG graphs. - Around 9:30 AM or 10:00 AM on tuesday it was clear that the circuits had not recovered fully.
- Sites were starting to move traffic to other paths around this time.
- This was good for them but made it harder to track the problem since there was no traffic.
- Worked with Amazon on traffic from Amazon to Internet2 for several hours.
- Realized after that there seemed to be a problem between Ashburn and McLean.
-This was not seen until traffic levels grew. - Tried several approaches
- Turned down peering.
- Needed to find a better way to put traffic on the link.
- Reloaded some line cards which seemed to help some.
- Moved the Amazon peering to Cleveland at around 3:30 PM tuesday. That seems to have resolved the problem.
Around 2:00 PM ET started to see some ASTRA issues on SIP.
- At first thought these were unrelated.
- Ultimately this traffic was seen to traverse McLean.
- Reset all of the line cards at McLean
- Seems to have addressed the issue.
Chris indicated a more complete report would be forthcoming later.

There is still work being done to research finding a reproducible cause. And this is still be watched closely. Chris will send out another update on this soon.
AL2S/AL3S:
- Initially it was decided to wait till after the holiday to make any changes.
- On Tuesday (3rd) the Amazon issues delayed making this change.
Darrell asked about the methodology for reporting on the availability of interfaces and ISIS uptime. Chris indicated this had been described in the initial emails but that he would resend it.

Face to Face meetings:
This will focus on several distinct issues by smaller groups. They will:
- prepare drafts on the topics
- these drafts would be sent on to the NTAC later
- These will hopefully be more regular events (yearly or so?)
- There are 30 attendees, 5 staff.
- Grover will send out a note on Wed about the topics that will be discussed.
Net+ services:
Blue Jeans network is coming up soon. The Microsoft peering is being worked on. Discussion will continue on Wed. A quick update will be sent to the list.
