Abstract:
1. A routing control method, comprising: providing an apparatus comprising a minimum cost path search processor and a predicted utilization transition data storage storing predicted utilization transition data in future for each resource in a network; said minimum cost path search processor reading out predicted utilization transition data associated with a received connection set-up request from said predicted utilization transition data storage; said minimum cost path search processor selecting a resource satisfying a predetermined condition; and said minimum cost path search processor detecting an arrival of a communication request for a large amount of traffic whose bandwidth or holding time is greater than a predetermined value, based on said predicted utilization transition data, and obtaining a cost of each said resource for a communication request for traffic other than said large amount of traffic based on said predicted utilization transition data relating to said arrival of said communication request for said large amount of traffic to select a first resource satisfying a second predetermined condition including a condition that a cost of said first resource is other than a minimum cost; and obtaining a cost of each said resource for said communication request for said large amount of traffic by using current utilization status data for each resource of said network, which is stored in a network context data storage, or by using static attribute information stored in a network data storage to select a second resource satisfying a third predetermined condition including a condition that a cost of said second resource is said minimum cost.
