ABSTRACT:
A designing and managing system for a communications network having a physical network and a logical network includes a designing system adaptable to a traffic fluctuation through a simple procedure, and a managing system for quickly selecting a suitable communications path in response to a path connection request and a path capacity change request. The designing system has units for respectively determining the topologies of the physical network and the logical network independently of traffic conditions, and units for setting the path capacities of the physical network and the logical network, respectively, based upon a long-term traffic demand and an actual request. The managing system includes a unit for registering the limited number of detour path candidates, a unit for determining the existence of a detour path in response to a virtual path connection request, and a unit, provided in a start point node of a communications path, for determining the acceptability of a change in the capacity of a path based on a value of a size of each link forming part of the communications path.
