Abstract

The invention relates to a method and a system for realizing Internet security protocol negotiation of 6to4 tunnels. The Internet security protocol negotiation of 6to4 tunnels is realized by setting a flag in data sent and a security strategy according to the flag, thus causing the 6to4 tunnels to realize Internet security protocol communication and providing safety guarantee for the 6to4 tunnel communication.

Description

technical field [0001] The invention relates to network communication technology, in particular to a method and system for realizing 6to4 tunnel Internet security protocol negotiation. Background technique [0002] With the rapid expansion of network scale, Internet Protocol version 4 (IPv4) cannot meet the needs of current and future network development due to factors such as too little address space and low security. With the rapid development of network technology, Internet Protocol version 6 (IPv6) appears. As an upgraded version of IPv4, IPv6 provides a huge address space and greatly enriches address resources. However, in view of the fact that IPv4 is a fairly mature technology with wide application and incomplete IPv6 technology and related equipment, it is impossible for the IPv6 network to completely replace the IPv4 network immediately, and it will take a long time to coexist with the IPv4 network to realize the transformation from IPv4 network to IPv6 Transition....
