METHOD FOR PERMISSION CONTROL AND ROUTING BY ALLOCATING NETWORK RESOURCE TO NETWORK NODE

摘要

PROBLEM TO BE SOLVED: To make it possible to extend technique for a reference node buffer managing system to a furthermore developed method by using only a specific buffer space out of buffer size B for calculation and fixing the band width of a channel. SOLUTION: When a communication device 105-i has a buffer request included in a node and also has a band width request included in a link 140-k, a requested virtual circuit(VC) is required to be routed on only a path including a node and a link having resources having an amt. enough for satisfying a certain request. When the VC is requested, an effective buffer request b0 and effective band width e0 are suitably determined as the functions of the parameters of the node 130-i and the link 140-k, i.e., buffer size and link capacity and the parameter of an access regulator 120-J. The rate of the width e0 to the capacity C of the link is suitably proportional to the rate of the request b0 to the node size B.
