1 draft-wing-behave-http-46-relay-02 1 Relaying HTTP from IPv4 to IPv6 draft-wing-behave-http-46-relay-02 IETF 76 – Hiroshima November, 2009 Dan Wing,

2 draft-wing-behave-http-46-relay-02 2 HTTP 4/6 Relay Useful for IPv6-only Servers Similar technique used today for IPv4 servers –Dyndns.org WebHop HTTP is the most critical application –80% / 20%

3 draft-wing-behave-http-46-relay-02 3 Mechanism 1: HTTP Relay Relay TCP traffic through an HTTP server HTTP Server uses clients Host: header to route HTTP traffic Layer 7 overhead (in HTTP relay) all incoming IPv6 connections come from HTTP relay –X-Forwarded-For header

4 draft-wing-behave-http-46-relay-02 4 Mechanism 2: HTTP Redirect Only initial TCP traffic hits HTTP server HTTP Server uses clients Host: header to send appropriate HTTP 302 redirect to client Layer 3 overhead (in translator)
