METHOD FOR DETERMINING ROUTING PATH ACCORDING TO DYNAMIC STATE CHANGES OF NODE

摘要

The present invention relates to a method for determining a data routing path in a communication network in which a plurality of logical networks share one physical network, and more particularly, to a method which: generates multiple routing paths from a source node to a destination node according to dynamic state changes of multiple nodes constituting a logical network; and calculates a routing cost of the multiple routing paths from a routing registry message received from the multiple nodes and from a processing-time shift value and a transmission-time shift value, shared by the multiple nodes, thereby determining the data routing path.
