Hurricane Electric IPv6 Native Backbone - Massive Peering! - IPv6 Routing and Peering on Hurricane Electric's Native IPv6 Backbone - T.1: IPv6 - Asia Ahead Of The World: 2009 IPv6 Tipping Point For The New Internet - (PPT)

摘要

All Internet traffic is contained within IP packets: Initially defined as IP version 4 with a fixed address size (32 bits); Designed as a research network - became a commercial; Works "perfectly" - until you run out of addresses; IPv6 (IP version 6) designed by IETF around 10 years ago: Handles much larger address space - 128 bits vs. 32 bits; Handles security, mobility, auto-configuration and more; Not well-suited to be backward compatible with IPv4; Only the IP layer is changed. TCP, UDP, or higher level protocols not affected: TCP or UDP packets are the same; Applications need to be IPv6 aware (DNS is needed).
