1. A traffic and topology independent communications network designing system for use in a communications network having a physical network and a logical network established among a plurality of nodes, comprising:

  • physical network topology designing means for setting a topology of the physical network independently of a traffic condition of the communications network;

    logical network topology designing means for setting a topology of the logical network independently of the traffic condition;

    physical network capacity setting means, coupled to said physical network topology designing means, for setting, based on a long-term traffic demand in the communications network, a capacity of a physical transmission line in the physical network having the topology defined by said physical network topology designing means; and

    logical network capacity setting means, coupled to said logical network topology designing means, for setting, based on an actual traffic demand in the communications network, a capacity of a virtual path in the logical network having the topology defined by said logical network topology designing means, whereintopologies and capacities of the physical and logical networks can be independently designed.
