Agenda
1. roster call
2. agenda bash
3. HOPI update
4. Circuits---non-layer 3 WG
5. Internet2 network updates
6. Commodity transit and peering WG updates
7. Open floor
a. Future of NTAC
b. Meeting times
1. Circuits---non-layer 3 WG
Cort mentioned that there is some interest in finding a way to standardize things sub-layer 3. He proposed having a group that would get together for a year and produce a recommendation on non-layer 3 services to be provided by the new network from the NTAC point of view. Discussion ensued as to whether the group would be a working group with a charter (what would the charter be?) or a SIG. The group could easily create a taxonomy of issues at lower than layer 3. Jerry Sobieski mentioned that he believed that the group could explore a broad scope for the first year and document areas of interest for the subsequent years. Jerry volunteered to work with Cort and John Streck to create a list of issues for the group.
2. HOPI update
Jerry reported that the rebuilding of HOPI on the new switches is underway. He also mentioned that they are doing some load testing on HOPI. Additionally, they are working on getting the GMPLS software to interoperate with the Cienas and, there are plans to port it to other platforms.
Jerry also mentioned that they have had training sessions to teach people how to build GMPLS control plane at Nysernet and also internal to DRAGON. Plans are underway for the following additional workshops:
May 2 and 3 at MAX headquarters)
May 30-31 NASA Ames (registration live on Internet2 site)
End of June in KC sponsored by Great Plains
North Carolina in early Aug
Wisconsin in September
Will then have one or two sessions prior to JT
Jerry noted that, if an organization is interested in hosting a workshop, the organization can contact Susan Evett.
Bill Owens mentioned that they are trying to get a 3750 for the HOPI project
Paul asked how they intend to address trust issues across borders
In path computation space, need to do constrained k-shortest path, have added two other constraints---time and policy
If request for a path comes in, can choose a path based on policy credentials associated with path; relationships have to be set up between peering networks, user may not know what authorizations are being used upstream
As far as security over control plane, have used GRE tunnels so can use generic IP address
If, at the edge, allow network to peer, how do you guarantee veracity of announcements?
Make an assumption about peers with BGP; same here
Some of the cross-domain topics that were discussed during the HOPI update are timely for the non-layer 3 working group
Rob mentioned that cienas support other services beyond the dynamic services mentioned by Jerrry
Rack lan management on STS channel on cienas
Internet2 network updates
Rob mentioned that he has been impressed by how well infineras working
Coordination issues in scheduling with qwest
Week behind in Atlanta
Regrooming Houston to Atlanta circuit
Will be ahead of schedule in reaching west coast
In terms of time commitments, are sticking to schedule
Dan and paul discussed that the peering working group would be suspended
Matt Z indicated that the peering group was going to poll connectors on business model and needs---would it be useful to do that?
Farmer: not useful to poll based on intentions but business models are useful
Reese indicated that he wouldn't respond to such a survey
Paul, in whatever merged org going to do with peering, it is a relevant piece of information to know whether have to build to peer
Tim has access to dynamic services and don't know what will be using after the merger
Farmer asked if, because peering is happening, is there anything that the WG needs to do to keep it alive?
working on getting additional peers in Chicago, not going to add any large contractual obligation; the service can grow even without additional contractual obligation
Wallace would prefer to have a working group to provide feedback to Internet2
Through discussions within WG, looked at issues that were of concern for creating services
It appeared that there were technical limitation to limit options and those options were no big deal
Farmer asked that tasks for group be evaluated
Wallace: could group poll for best practices and observations on use?
Collection of knowledge that the users have to share with others
Many of the current peering users in NTAC or on the peering working group
Reese: would like to see a design that everyone uses it because CENIC can not use it; he believes that it wouldn't be free if everyone could use it
Could quilt information be used to do some analysis on costs for peering?
If can get better service from peering than from a cheap internet service provider, that is worth paying a bit more
Many people in the group mentioned that there is value in peering
Based on experiences that people have had, build a more detailed FAQ/best practices
Want group to continue and work on that; Wallace will lead FAQ effort
Pursuing a technical architecture for the all Internet2 members will be postponed until the merger decision is made
Expectations document
Dave Reese indicated that he has started on document describing membership and how the NTAC operates. Dave asked if group wants to continue with this document and what needs to be communicated prior to the councils being formed. Paul Schopis asked if the NTAC wants to approach the new governing bodies and ask that the NTAC continue.
Cheryl indicated that she hopes that the councils would use the NTAC as a working group and that the councils would ask this group for technical advice before making policy/business decision.
Dave Reese will create a document describing the NTAC so that councils can make an informed decision regarding how to work with the NTAC.
Open floor
Discussion ensued regarding the scheduling of NTAC meeting at face-to-face. There was a suggestion to combine NTAC meeting with RON/gigapop meeting and to work with Heather to decide what want to do with time designated to RON/gigapop BOF. Dave Reese suggested that the NTAC give updates on what they are doing during the BoF rather than it being a business meeting of the NTAC. It was also suggested that the BOF time be used first for updates and then the business of the NTAC be opened. There was agreement that the group is open to anyone who wants to join.
Dave Farmer suggested that the NTAC move forward with work as if the group will continue to exist until there is an indication that it should be otherwise.
The next NTAC call will be June 5, 2007.
