Internet2 network infrastructure

• IPv6 continues to perform well on the Internet2
  Network
• Transition from Abilene layer3 network to new
  Internet2 network infrastructure complete done
  by 30-Sep
• Using same Juniper T640 routers still running
  dual-stack IPv4 and IPv6
• The backbone now supports 32 bit ASNs

7
Internet2 network infrastructure

• RE peerings remain unchanged
• IPv6 peerings with commercial nets remain at
  PAIX, now served by Los Angeles router
• With new commercial peering service, new
  opportunities to peer in Chicago, New York,
  Seattle and Los Angeles
• Hence near-term change commercial IPv6 to its
  own VRF

8
Internet2 Network VRFs

• Research and Education
• Our connectors
• Our peers (GEANT2, APAN, JGN2, )
• IPv4 and IPv6
• CPS (peering service) IPv4
• CPS (peering service) IPv6
• Connectors can peer with each individually to
  keep current state, encourage CPSv6, even if no
  CPSv4

9
Monitoring

• Monitoring and network test points still being
  updated for the new network
• We have at every router node
• Latency (owamp)
• Throughput (bwctl) 1G, 10G upon request
• On-demand testing (NDT)
• All supporting IPv6

10
Monitoring

• Consider testing to Internet2, at least ad-hoc,
  and possibly low-rate periodic
• Owamp, and bwctl TCP tests lt 30s to 1G endpoints,
  are no longer restricted
• Please tell us if you set up periodic tests
• Recent testing of peering points with DREN has
  exposed odd routing, configuration errors

11
Monitoring

• We have firewall filters installed in the Juniper
  routers to capture IPv6 utilization (and other
  specific port counts)
• http//vixen.grnoc.iu.edu/jfirewall-viz/index-bits
  .html (bits/sec)
• http//vixen.grnoc.iu.edu/jfirewall-viz/
  (packets/sec)
• Question what are you doing for flows?

12
Policy Interconnection with other networks

• Will continue to peer with IPv6 commercial
  networks
• With new Internet2 network, will also now peer
  with IPv4 commercial networks (but these are a
  separate VRF, no mixing with RE routes)
• No transit between non-US networks and commercial
  IPv6 network peers
• Had been providing transit between v6 networks
  (including commercial)
• Stopped providing transit to commercial v6 peers
  not their usual policy

13
IPv6 Activities

• Internet2 IPv6 Working Group
• Refocused from campus deployment effort to..
• Working with middleware and applications working
  groups as resource
• Renewed interest in moving IPv6 to mainstream
• Internet2 IPv6 Hands-on Workshops
• Lesser in frequency, but still being held by
  request

14
Pointers

• IPv6 working grouphttp//ipv6.internet2.edu/
• Internet2 NOC IPv6 Informationhttp//noc.net.inte
  rnet2.edu/i2network/maps--documentation.html
• Presentation and exercises from IPv6 Multicast
  Workshop http//multicast.internet2.edu/workshops/
