International Connectivity International Task Force Meeting Fall 2005 Internet2 Member Meeting 19 September 2005 Philadelphia, PA USA 19 September 2005 Philadelphia, PA USA

2 International connectivity Transatlantic Networking in the LHC Era -Harvey Newman, CalTech (USA) ESnet international update - Joe Burrescia, ESnet, (USA) Abilene International Connectivity -- Peering policies, implementation and new updates – Ana Preston, Chris Robb, Brent Sweeny (Abilene NOC/Engineering) IRNC Program and Updates TransPAC2 TransLight/StarLight WHREN GLORIAD TransLight/Pacific Wave

3 Abilene International Connectivity Non-US network has to be under the cover of a Memorandum of Understanding (MoU) between Internet2 and in that country, that organization with goals and objectives similar as those of Internet2 in the United States. The non-US network with who we interconnect must complete an Interconnection Agreement with Abilene (also referred to as a Peering agreement) direct peerings with Abilene (network with networks behind)

5 Peering with Abilene How? Via international exchange points via international links (often funded by US agencies like National Science Foundation) if via a layer-2 exchange point (i.e., where non-US network is expected to connect to a Layer 2 switch) a VLAN is set up between Abilene and the non-US peer Other alternatives: reviewed case by case Other alternatives include via eBGP multihop peering(s) and GRE/MPLS tunnels

6 International connectivity September 2005

7 International Transit Network service -Unless noted, implemented for all non-US peers -Transit to Fednets (over Abilene) for non-US peers (and viceversa) -Only if requested by both peers (peers to work out any conditions) -Case by case review -Please contact Ana for more information.

8 Issues to bring up Transit: Want to make sure we better understand what other networks are transiting our international peers Route preferences (with multiple links, which one is preferred?) IPv6 (Brent Sweeny)

Abilene IPv6 routing policy Matt Davy – Abilene NOC Presented by Brent Sweeny – Abilene NOC Matt Davy – Abilene NOC Presented by Brent Sweeny – Abilene NOC

11 Abilene IPv4 Unicast Routing Policy Relaxed COU for “Advanced Services” (Multicast and IPv6) In Practice = Full Route Swapping MIX (California): some multicast, very few IPv6 Background

13 Added Peering at PAIX Palo Alto (California) ISPs only want our “customer” routes Abilene has global IPv6 connectivity (roughly 850 routes) Kreonet (Korea) appears to be the only network providing “transit” to Abilene roughly IPv6 routes go through Kreonet complaints of very long paths between Abilene and commercial ISPs, especially in Europe Recent changes (and consequences)…

14 Should Abilene provide global IPv6 connectivity ? Can campuses & gigapops get “reasonable” IPv6 service from ISPs ? Is there an acceptable multihoming solution that works for everyone ? Questions

15 How can Abilene increase the robustness of its IPv6 peering? Commercial peering at both coasts (and midwest)? Transit from more than 1 provider ? How much bandwidth ? Should we pursue robust peering in addition to transit providers Questions

16 Should IPv6 policy match IPv4 Unicast policy ? Should Abilene accept commercial IPv6 routes from Connectors and other NRNs ? Example: Korean R&E network advertising IPv6 routes to Korean ISPs Questions

17 Discussions over the past few months on how to proceed Exploring IPv6 transit options with ISPs Reviewing the Abilene ITN policy - will take into account IPv4 Multicast & IPv6 as well as IPv4 Unicast What are the IPv6 peering policies of our peer R&E networks, both US & international? What should those policies be? Direction
