A communication network comprises a first switching node (A), a second switching node (C), a first, a second, and a third network paths connecting the first and second switching nodes, a bidirectional connection (LSP1) established along the first network path, a first unidirectional connection (LSP2) provisioned along the second network path, a second unidirectional connection (LSP3) provisioned along the third network path, wherein the first and second unidirectional connections have opposite flow directions,
wherein at least one of the first and second switching nodes comprises a first switch-over module for performing a switch-over action between a first flow direction of the bidirectional connection and the first unidirectional connection,
wherein at least one of the first and second switching nodes comprises a second switch-over module for performing a switch-over action between a second flow direction of the bidirectional connection and the second unidirectional connection. In embodiments, the connections are arranged as Label-Switched Paths between GMPLS nodes. |
