1 Mar 5th, 2002, IPv6 Technical SIG, 13 th APNIC Open Policy Meeting 1 User Network Interface - auto-configuration mechanism - Toshi Yamasaki IPv6 Operation Study Group / NTT Communications

2 Mar 5th, 2002, IPv6 Technical SIG, 13 th APNIC Open Policy Meeting, Toshi Yamasaki 2 Goal IPv6 access services for everyone (non- technical customers) in 2002 ex) DSL, FTTH, D-up, CATV, etc. Make a rough consensus for “what are minimum requirements for ISP-to- Customer auto-configuration?” No absolute conclusion, but need a current conclusion to start businesses

3 Mar 5th, 2002, IPv6 Technical SIG, 13 th APNIC Open Policy Meeting, Toshi Yamasaki 3 Scope ISP-to-Customer Environment PE-to-CPE Interface CPE-to-Host Interface ISP POI Service Host CPEPE access mediaLAN Here

4 Mar 5th, 2002, IPv6 Technical SIG, 13 th APNIC Open Policy Meeting, Toshi Yamasaki 4 Auto-configured Parameters Site Address Prefix / Host Address DNS Cache Address

6 Mar 5th, 2002, IPv6 Technical SIG, 13 th APNIC Open Policy Meeting, Toshi Yamasaki 6 Challenges for IPv6 world... universality should be applicable for various medias shouldn’t assume PPP(IPv6CP) “third-party-serverless” auto-configuration should be auto-configured by the service entity itself, only when it is alive Site-Prefix by who provide the routing service for the prefix, DNS Cache Address by who provide DNS Cache service non-PC Hosts are not always powerful no heavy requirements
