Title: Network system and load distribution method
Inventor: IKEDA NAOYA
IPC: H04L45/24
Filed: 2002-07-03
Abstract: PROBLEM TO BE SOLVED: To reduce load on a load distribution device for an Web server within a site and quickly switch paths, even if a trouble is occurred on a path to the load distribution device. SOLUTION: A router 14 sets identical network addresses to a plurality of paths and assigns accesses to a plurality of load distribution devices A15 and B16, by using a function of assigning to each path, based on the result of calculating of Hash values. Load distribution devices A15 and B16 assign accesses to Web servers 17a-17d in round-robin scheduling by using a LAN function owned by themselves. Accordingly, uniform assignment of input to the router 14 to the Web servers 17a-17d can be made, a site 10 can continue services without the loss of high speed and high reliability, even if traffic is increased suddenly. Even if troubles occur between the router 14 and the load distribution devices 15, switching of paths to other load distribution sides can be made instantaneously.
