Title:
FIRST RELAY SERVER AND SECOND RELAY SERVER
Document Type and Number:
WIPO Patent Application WO/2010/103781
Kind Code:
A1
Abstract:
A communication technique which constructs a communication system in which communication terminals communicate through a WAN, as well as has excellent flexibility and scalability. A relay server (12) and a relay server (23) share relay group information and relay server information. The network address of an LAN (1) in which routing control is performed through the relay server (12) and the network address of a LAN (2) in which routing control is performed through the relay server (23) are registered in the relay group information. The relay servers (12, 23) establish a routing session through a WAN (3). If a communication terminal connected to the LAN (1) sends a communication packet which designates the IP address of a communication terminal connected to the LAN (2), the communication packet is encapsulated and routed using the routing session between the relay servers (12, 23).
