Abstract:
A telecommunication network based on distributed control, comprising:a plurality of switch nodes having switch fabric devices containing connection-oriented switches for exchanging user information between subscriber lines and trunk lines by connection control operations, and signal devices for sending and receiving control signals through said subscriber lines and said trunk lines;a plurality of control nodes for executing connection control operations for said switch nodes by sending and receiving control messages with said switch nodes;a control network for performing message communications between said switch nodes and said control nodes; anda user information network for transferring said user information;wherein said control network connects said switch nodes and said control nodes by connection-oriented or connectionless communications, said control nodes and said switch nodes send and receive messages for communicating with other nodes through said control network, and each of said control nodes controls a plurality of switch nodes by delivering messages to the destination nodes, specified by routing information in said messages; andwherein said control network and said user information network are integrated into a single network.
