Abstract
When service is allocated to a server of the other network on the basis of load information, a packet from a client is transferred as a transfer packet to the other wide area load distribution apparatus. The other wide area load distribution apparatus fetches the client packet from the transfer packet and converts its destination from a transferor address Lx to a server address S and its sender from a client address C to a self address Ly for sending to a server. Upon a reception of a response server packet from the server, the destination is converted from the self address Ly to the client address C and the sender is converted from the server address S to the transferor address Lx for the relay to the client.
