Wide area load distribution apparatus and method

摘要

A wide area load distribution apparatus and method for allocating services to servers of other networks on the basis of load information. A packet from a client (16) is transferred as a transfer packet to another 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 (14-11). Upon reception of a response server packet from the server (14-11), 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 (16).
