Meeting Notes
1. NTAC Updates
Paul Schopis mentioned that John Moore was elected NTAC Vice Chair at the SMM. John, Paul and Linda met last week and talked about evaluating the NTAC over the next seven months including discussion of the working groups. Earlier, the NTAC had discussed the idea of creating task forces with a specific charge, completing the charge and dissolving the task force and that idea is being discussed again. Additionally, when considering current working groups, if no report is received from the working group for three months, the Chair or Vice Chair will talk to the working group chair to try to determine what is preventing the delivery of a report and to decide on the next step for the group.
2. Update from Internet2
Chris Robb provided an update. He mentioned that a bug in the infinera hardware was identified by Juniper. It has been resolved now and Level 3 has tested the code with the fix in the lab and the fix will be deployed in June. The bug resulted in less than one sec outages on some or all waves on a segment and the patch will resolve it. Chris mentioned that the KyRON upgrade to 10G has been processed this month and that USF/FLR moving behind new 10G (Dave Pokorney added that USF moved to FLR today and production traffic on the link today). Chris went on to say that Internet2 staff plan to swap out Juniper T640 and replace them with MX models in three locations. The swap will occur prior to the start of the fall semester although the details of the swap are being worked out and will be shared with the community over the coming weeks.
3. Update from AOAC
Paul Schopis mentioned that the AOAC has changed the format of their meetings. Although the AOAC will continue to have two calls each month, it was decided that one call will focus on strategic issues and the other call will be brief and focus on updates from Internet2 staff. At the SMM, after the AOAC face-to-face meeting, a small group from the AOAC held a meeting with Internet2 senior staff to talk about the future of DCN including current status and future directions while considering the needs of LHC as well as costs to the connectors. The conversations regarding DCN continue within the AOAC. Paul also noted that, during the SMM, the RAC endorsed moving forward with DCN.
4. Update from Peering Working Group
Jeff Bartig mentioned that CPS and TransitRail staff have been working together on plans for the consolidation of the services. Additionally, Internet2 staff have been planning for the CPS fall expansion as well as expansion into Equinix-Ashburn, ensuring that CPS decisions are consistent with longer range plans for consolidation. Earlier today, Jeff sent an email earlier asking for comments on equipment that is being considered. Input can be shared via ntacpeering@internet2.edu or directly to Jeff Bartig.
Paul asked if there were functional requirements that the box needs to meet. Steve mentioned that the equipment needs to accommodate IPv6 and multicast gateways as well as IPv4.
5. Report from DCN Working Group
Linda Winkler was unavailable.
6. Report from Routing Policy Working Group
David Farmer was unavailable.
7. Update on Performance Working Group
Carla Hunt was unavailable and indicated that she had no updates for the group.
8. Update on ARIN issues
Paul mentioned that Dale was recently hired by Internet2 and that chairs of the working groups need to be a member of the community rather than Internet2 staff. Michael Lambert mentioned that David Farmer would be a good source of information as he is on an ARIN council. Those on the call agreed that it is important that someone from the NTAC be paying attention to ARIN happenings on behalf of the community and Paul asked that those on the call consider making a recommendation of someone to serve this role.
9. Phoebus/Bulk Transport
Steve Senger indicted that they have been making progress on revised mission statement and read the following to the group:
The Transport Working Group recommends that the current Phoebus deployment be completed by adding depots at DC, Atlanta, Kansas City, Salt Lake and Seattle. Members within the group have recently been experimenting with the service in a variety of contexts including transport within distributed storage networks such as REDDnet and interactive visualization applications. These experiments have indicated that Phoebus can provide significant improvements in performance. In addition to recommending completion of the deployment the Transport group recommends that the NOC begin regular monitoring of the operational state of the depots and that tools be created to allow experimenters to determine whether the Phoebus Depots are operational over a given path. Lastly, understanding that a complete 10G deployment may be cost-prohibitive, support of 10G Phoebus nodes in strategic locations, for e.g. international peering, should be considered.
Steve mentioned that this resolution was created after success with the deployment of Phoebus was reported. In response to a question regarding interaction with the NOC, Steve indicated that conversations with the NOC have yet to begin. He also mentioned that cost models have been created but weren't available during the call. He indicated that the group would be looking to Internet2 to fund this as the deployment is still at an experimental stage.
Paul suggested that a motion be made to accept the study, as written by the working group, and to have Internet2 staff evaluate cost models as well as investigate what would be required of the NOC to do regular monitoring.
John Moore made a motion to move the recommendation forward. The motion was seconded by Steve Senger. No objections were voiced to the motion and the motion carried. Paul asked that Steve Wallace take the recommendations to Internet2 staff.
10. Information & Infrastructure
Martin Swany was unavailable and sent the following report that was read by John Moore:
* Face to face meeting at SMM focused on defining information service use cases. Representatives from several groups (perfSONAR/DCN/SDN) were present. Also discussed ongoing work in all groups regarding authentication and authorization and how this will affect information discovery.
* IP Summarization work being researched and tested by University of Delaware student Marcos Portnoi is nearing completion. His work will be evaluated by perfSONAR developers for inclusion in a future release. A research paper is also being explored.
* Open Grid Forum (OGF) event was held 4th week of May with Jason/Martin in attendance. Unified Network Information Service (UNIS) requirements discussed in the WG were presented and will form the basis of a standardization effort for perfSONAR/DCN protocols.
