The present invention discloses an IPv6 trusted network-based reconfigurability implementation method and belongs to the computer network technical field. The method is designed according to the multi-layer multi-level structure and deep coupling characteristics of a modern enterprise network architecture and based on the equality feature and scalability feature of a P2P (peer-to-peer) network. With the method adopted, the definability and reconfigurability of an IPv6 trusted network can be implemented. According to the method, networking equipment is divided into peer-to-peer network entities, namely, trackers and peers; the implementation of protocol interaction between the trackers and the peers as well as between the peers is introduced; and an IPv6 trusted, definable and reconfigurable network architecture can be realized. Breakthroughs are made in the multi-layer multi-level structure and deep coupling structure of a traditional network, and the more flexible and easily-scalable P2P peer-to-peer network is utilized to carry out networking configuration; and therefore, a guarantee can be provided for the definability and reconfigurability of the IPv6 trusted network in an architecture level.
