摘要：A communication network comprises a first switching node (A), a secondswitching node (C), a first, a second, and a third network paths connecting the first andsecond switching nodes, a bidirectional connection (LSP1) established along the first

network path, a first unidirectional connection (LSP2) provisioned along the secondnetwork path, a second unidirectional connection (LSP3) provisioned along the thirdnetwork path, wherein the first and second unidirectional connections have opposite flowdirections, wherein at least one of the first and second switching nodes comprises a firstswitch-over module for performing a switch-over action between a first flow direction ofthe bidirectional connection and the first unidirectional connection, wherein at least oneof the first and second switching nodes comprises a second switch-over module forperforming a switch-over action between a second flow direction of the bidirectionalconnection and the second unidirectional connection. In embodiments, the connectionsare arranged as Label-Switched Paths between GMPLS nodes.
