Abstract: |
The invention is used in IPv4/IPv6 dual-stack router and IPv4/IPv6 dual-stack tri-layer exchanger to transmit IPv6 over IPv4 tunnel endpoint message on IPv4 by using P2P overlay network. Therefore, 6 kinds of control packet and 4 kinds of adjacency state are set on nodes of P2P overlay network, and meanwhile a central register is set to receive the joining request of new node, and the relevant protocol process, protocol packet type and protocol state machine for use in building and maintaining the P2P overlay network, keeping neighboring relationship and transmitting tunnel endpoint message are designed. |
