IPv6 over IPv4 transition method and apparatus for improving performance of control server

摘要

The present invention relates to a method and apparatus for performing IPv6 over IPv4 transition to improve performance of a control server. When an edge router selected by the control server according to a tunnel creation request of an IPv6 terminal receives a tunnel creation request message from the control server, the edge router transmits a tunnel creation response message for the received tunnel creation request message to the IPv6 terminal through the control server, and the edge router performs IPv6 over IPv4 transition through a tunnel created by the IPv6 terminal that received the tunnel creation response message so as to improve the performance of the control server. Therefore, loads of the control server occurred because all terminals set control tunnels to the control server can be prevented, and service extensibility due to the increase in the number of subscribers can be guaranteed.

1. A method of performing IPv6 over IPv4 transition to improve performance of a control server, the method comprising:
selecting, by the control server, a router among a plurality of routers based on status information of the plurality of routers; receiving, by the selected router, a tunnel creation request message from the control server; transmitting a tunnel creation response message, in response to the tunnel creation request message, from the router to an IPv6 terminal through the control server; creating a tunnel between the router and the IPv6 terminal; performing IPv6 over IPv4 transition via the selected router, without involving the control server, upon a request for information on a reception terminal, which is received from the IPv6 terminal through the created tunnel; and forwarding data between the IPv6 terminal and the reception terminal through the created tunnel without involving the control server, wherein the status information of the plurality of the routers includes a number of tunnels that are currently set, a number of tunnels that can be added to be set, and an amount of data used for the tunnel.
