An alternate path can be established in a connection-oriented packet switching network by correlating the bandwidth reservation of this alternate path with the bandwidth reservation of an active path on trunks through which both paths pass. The alternate path that is established can have one or more of a number of different attributes that vary from the attributes of the active path. The alternate path is established in a connection-oriented network with bandwidth correlation in three stages: a keying stage, a correlation stage and, a transfer stage. An alternate path may be established without a double reservation of bandwidth, thus making efficient use of limited network resources.
A connection-oriented packet switching network including a plurality of switching nodes interconnected by transmission links, and in which data packets are transmitted on an active path between a source node and a destination node wherein bandwidth is allocated by means of a bandwidth reservation on all transmission links between said source node and said destination node for said active path, said connection-oriented packet switching network comprising:
A connection-oriented packet switching network including a plurality of switching nodes interconnected by transmission links, and in which data packets are transmitted on an active path between a source node and a destination node wherein bandwidth is allocated on all transmission links between said source node and said destination node for said active path, said connection-oriented packet switching network comprising:
A method of establishing an alternate path between a source node and a destination node in a connection-oriented packet-switching network including a plurality of switching nodes interconnected by transmission links, and in which data packets are transmitted on an active path between said source node and said destination node wherein bandwidth is allocated by means of a bandwidth reservation on all transmission links between said source node and said destination node on said active path comprising the steps of:
