completely jointly usable communications network

摘要

The architecture of a communication network comprising a plurality of nodes interconnected by a transmission facility having a bandwidth divisible into channels of respective bandwidths, e.g., optical fiber, is enhanced by fully sharing the network bandwidth among the network nodes, such that each pair of nodes, on periodic basis, dynamically establishes respective direct links to each of the other network nodes, in which a direct link is formed from a group of channels obtained from the network bandwidth. The remaining bandwidth is then used to form a pool of bandwidth which is shared among the network nodes on a dynamic basis, such as, for example, establishing a communication path between a pair of nodes to route a call from one node to the other node of the pair of nodes.
