3 IPv6 Distributed Labs Why IPv6 Distributed Labs? Stable R&D testing platforms are needed to: Adapt current network and final-user services to v6. Deploy new network and user services in v6 Networks. Ensure IPv4-IPv6 interaction at Service level. Several Scenarios => Join partner s Labs (distributed topology) Objectives Propose solutions for IP network & services evolution. Feedback to standarization bodies and developers. It happened before: Current Internet services came from IPv4 R&D stable Labs linked together.
4 IPv6 Distributed Labs (II) IPv6 Distributed Lab = v6 Nodes + IPv6 Backbone (links, routing) Alternatives for the backbone Links Deployment Public L2 Networks: Guaranteed BW, expensive for R&D purposes. Research networks: Still Based today in IPv4: Tunneling needed. Deploying QoS scheemes at IPv4 level. NRENs: within a single country. GEANT: connections over 2 or more NRENs. Tunnels over Internet: Straight solution, best effort, low BW. New Alternative: Large IPv6 projects: Euro6IX / 6NET. BW Considerations Best effort & Low BW enough in most functionality/basic services experiments. Guaranteed High BW is needed in some user services experiments.

18 Conclusions Built an stable IPv6 Distributed Lab with SERVICES. REAL USE of these services: ISABEL for most project meetings ( 14,315 E saved in travel costs). IRC used to set up & operation event platforms (v6 & v4 accesses used). Planned: IPv6 Mailboxes in v6 MTAs (To send if v4 MTAs fail...) Redirected to current mailboxes (do not want 2 mailboxes). ralli@tid.ist-long.com =>ralli@tid.es WEB Tools: Internet users may access from IPv6 tools: ping, traceroute, AS path tool. IPv6 services: LDAP, mail, network statistics. Transition Mechanisms Today: NOT testing ALL combinations. TM ONLY used when needed to provide one IPv6 LONG service to the v4 Internet. Next Step: Use other TM to provide v4 Internet services within our v6 net.
