Abstract: A method of path restoration in an ATM network which attempts to minimize the loss of cells in the event a node or a link fails. The method is suitable for failures in point to point Switched Virtual Circuits (SVCs) in ATM networks and makes use of the bi-directional properties of point to point SVC calls. The method permits the construction of an ATM network which includes call path redundancy whereby if a node or link fails, another path meeting the requirements of the call (if one exists) will be used on an automatic basis. The alternative or redundant path is placed into service in such a way that the flow of data is substantially constant. The switching of the path occurs with almost no data loss and without the overhead time associated with Q.SAAL based detection and signaling.
