Abstract: A selective VP protection method in an ATM network for protecting a virtual path connection selectively employing VP end protection and arbitrary VP protection is proposed. In the method, the VP-AIS cell which is transmitted downward by each failure detecting node is composed including an area for carrying a switching flag which indicates the presence or absence of execution of the arbitrary VP protection by the failure detecting nodes. When an ATM cross-connect node capable of executing the arbitrary VP protection detected a line failure, the failure detecting ATM cross-connect node determines whether or not it executes the arbitrary VP protection in order to relieve the line failure, and transmits downward the VP-AIS cell in which the switching flag has been set according to the determination.
