Abstract:
A routing system for establishing a plurality of connections having Virtual Channel Identifiers (VCIs) or Virtual Path Identifiers (VPIs) for each call between a transmission terminal and a reception terminal through a plurality of nodes, prior to transmission of information from said transmission terminal to said reception terminal, and for selecting one connection from among said plurality of connections for each unit of information;said routing system comprising:means provided at at least one of said nodes, for a section where all of said connections take different routes, for establishing said connections without changing the routes, and for a section where at least two connections take the same route, for combining said connections that take the same route into a combined connection having one VCI or one VPI; andmeans provided at at least one of said nodes, for making arbitrary connections between a first connection at an input side of said at least one of said nodes which is a combined connection or is selected from a plurality of connections, and a second connection at an output side of said at least one of said nodes which is a combined connection or is selected from a plurality of connections.
