A network is arranged to generate circuits between source node (N.sub.S) and destination nodes (N.sub.D) by means of datagrams which are guided at each node over a path (D) which minimizes delay in establishing the circuit. Certain sub-destination nodes (N.sub.B and N.sub.C) are designated as intermediate...http://www.google.de/patents/US5142531?utm_source=gb-gplus-sharePatent US5142531 - Data communications network
