Updates:
V6:
-Not all that much activity of late.
-Sumon is doing a v6 class next week.
-Alan is working with APAN on topics for the all day meeting at TIP.
Peering and Routing:
-They continue to have regular calls.
-Get updates from the TR/CPS engineering staff
-Discussing possible performance metrics for the L(3) network. Jeff intends to expand this to the whole group and bring together a smaller focus group.
Performance:
-No one present
SDN:
-On the last call talked about the GENI terminology and how to make it more generally understood.
- Deniz discussed some of her research.
-There has been a discussion about the idea of Open Flow (SDN) peering on the mailing list. This discussion will continue. The GLIF has a similar discussion going on.
-They will be having a WG meeting at TIP. Looking for agenda topics.
Internet2 Update:
1) The transition from the Infinera system to the BTOP funded Ciena system is complete. The last waves were moved over last friday (11/30/12). The NOC has stopped monitoring the Infinera system. Chris pointed out that the Infinera system was a leased system and that Level (3) is planning on repurposing the network. This in response to some earlier questions about availability of parts from that network.
2) There has not been any upgrades to the Juniper software in some time. After a recent upgrade there is an issue with some of the SNMP polling activity. It is a result of polling the LAG's that are in place. The result of this is that on the Weather map there will be black lines from time to time, mostly starting in Chicago. A code release, 12.1.04, had been obtained that should fix the issue.
3) Internet2 is looking at both the KC-> Chicago route and the DC -> Atlanta route for possible enhancements. Both paths are showing heavy use. Likely will look at adding more 10G now with an eye toward going to 100G later after the MX swap.
4)The Advanced Layer 2 Service network has some new connectors. OARnet and Indiana University have joined at 100G. Magpie has also connected. They join ONEnet.
5) There are a few new projects starting:
- Deploying the new MX routers.
- This will get going in earnest during the 1st Quarter of 2013.
- Currently looking at prioritization of locations. If anyone has a reason or need for an MX in a particular router location please let Internet2 know.
Bill Owens asked about how deeply into the regional or campus network the AL2S capabilities were installed.
- At this point we are not really sure. MAGPIE does have an IDC running. IU and Ohio seem to be using the 100G link now mostly for IP backhaul. They are allowed to access their contracted IP bandwidth over the Advanced Layer 2 Service network.
Jeff Bartig asked about public access to tools like Looking Glass for the AL2S devices. It was pointed out to them that there were links on noc.net.internet2.edu for the available tools.
Roy Hockett asked about plans for accommodating larger then 10G flows for other networks that attach to Internet2. These would be sites like ESnet and projects like LHCONE. In general this should not be a problem. There are 100G connections to most of the Exchanges now (Pac Wave and Starlight in process) and Internet2 and ESnet are talking about the details of interconnecting their networks at 100G.
The MX's that were purchased for the AL2S network do have more 100G cards then are currently available on the T1600's.
At some point Internet2 and the NTAC should have a conversation about the headroom policy on the 100G network.
Jeff Bartig asked if the same number of interfaces were purchased for the MX's as already existed on the T1600's?
- There were certainly enough interfaces bought to cover all of the existing 10G interfaces. As well there were more 100G interfaces bought.
Follow on question: Will connectors have the option to connect to the routers at 100G? - That will continue to be an option, just as it is now.
- It will be possible to get 100G in Chicago for instance however that can be supplied, either by upgrades to the MX's or other means.
Advanced Layer 2 Services node discussion:
Besides the Brocades the BTOP funds were used to obtain 10 more MX's for AL2S. This is an opportunity to open the discussion about where those devices need to go. At present Jacksonville, Raleigh and Seattle are certainly planned. Internet2 is interested in hearing where the community might like the rest of them to be located. Do not feel like you are constrained in making suggestions, this should be considered an invitation for this discussion.
These devices are BTOP funded. As such they need to be installed no later then June 30, 2013. The intent would be to have them in place sooner, perhaps a March /April timeframe.
ION Architecture:
There was discussion about possible changes in the ION architecture. These would involve moving the backbone traffic over to the Advanced Layer 2 Services Network. This is very early in this discussion, very much in the investigation phase. If anyone has any input about this they should contact Dale. As this is tested results will be made available.
Cas d 'Angelo expressed how much everyone appreciated the work that Akbar has done over the past year in the NTAC.
