<P>PROBLEM TO BE SOLVED: To obtain a communication network system distributing processing loads of a plurality of servers providing the same service. <P>SOLUTION: In the communication network system including a plurality of sub-networks, a server, including a first address associated with a provided service and a second address indicative of the self-server, notifies the first and second addresses and processing load information, to a boundary router subordinate to the same sub-network. When a client requests a predetermined service, the client transmits a packet having a set address associated with the service. The boundary router retains the notified information and advertises the first address, the processing load information and the address of the self-boundary router to another boundary router, and on receiving a packet from a client subordinate to the same sub-network, determines a transfer destination, based on the destination address, the information notified from the server and information advertised from the other boundary router. <P>COPYRIGHT: (C)2013,JPO&INPIT |
