<p>When it is determined in a simplex method whether or not the existing path realized by routers R1 to R7 configuring a network can support the requested traffic, the optimal traffic distribution can be obtained although a prepared path group has a bottleneck link and has no sufficient band in a prepared path, etc. When there is no optimal solution in the simplex method, a bottleneck link is found, a bypass is added, and the simplex method is further applied. Thus, it can be determined whether or not the requested traffic can be accommodated by the current path. When it cannot be accommodated, only a necessary path can be added, and the optimal traffic distribution can be performed by setting the objective function based on the network cost such as the consumption of network resources, a delay, the number of hops, etc.</p> |
