COMPLETELY SHHRED COMMUNICATION NETWORT AND METHOD OF COMPLETELY SHARING COMMUNICATION NETWORK

摘要

PURPOSE: To improve the path selection of calling in a large scaled communication network by escaping the idea of a logical network and allowing a node to dynamically and completely share the band width of a communication network. CONSTITUTION: Plural exchange centers such as nodes 25, 30, 35, 40, 45 and 50 mutually connected through a network transmitting facility 100, that is, the blocks of a digital public exchange facility network 200 equipped with nodes are shown. The bands of the communication network are periodically assigned among the nodes of the communication network as a rule, and each pair of nodes establishes a direct link with the other node in the network for realizing the path selection of calling. Moreover, each direct link is formed of more than one channel groups related with the calling of each kind of service. Then, the residual communication network bands are ensured for being used as the resource of band width to be dynamically shared. Thus, it is not necessary to enable any substitute path selection.
