Abstract
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.
