Experiences with Application Services Most of the experience scenarios were included into the stable infrastructure G Seek for easiest (regarding to user deployment) strategy in mixed IPv4/IPv6 G networks I ISABEL and transition mechanisms (6to4, NAT-PT) I DNS and Web server performance, I DNS, Web, FTP, News, LDAP, Mail through NAT-PT I IRC through TRT I NFS over IPv6, and IPv4 NFS clients accessing IPv6 servers (FreeBSD) I Also tested ISATAP and DSTM deployment LONG: Laboratories Over Next Generation Networks.
Conclusions Several scenarios in which most relevant standard network applications working G seamlessly for IPv6 clients, and also for IPv4 clients DNS, Web, FTP, News, LDAP, Mail, IRC, … ISABEL I If translation is required, I – Sometimes this implies special configuration (for example, detailed configuration of NAT-PT address maps) – Known problem for applications transporting addresses Missing DHCPv6 (debate for its need), required better support for NFS I Next step: adapting less standard applications, and ease transition I Equipment support G Required better support for several link layers (ADSL, CATV) I Gigabit routers beginning to perform IPv6 forwarding by hardware I Advanced features G Mobility in general offers better support for IPv6 than for IPv4 I Diffserv and multicast working similarly to IPv4 I Although much work required for mixed IPv4/IPv6 environments I Multihoming and anycast are still not properly solved I Some contributions have been made to multihoming (see WP5) I LONG: Laboratories Over Next Generation Networks.
