Health probing detection and enhancement for traffic engineering label switched paths |
摘要 |
A method performed by a network device may include establishing performance-based Bidirectional Forwarding Detection (BFD) sessions for each link of a primary traffic engineering Label Switched Path (TE-LSP) and establishing performance-based BFD sessions for each link of a secondary TE-LSP. The method may also include, monitoring performance of the primary TE-LSP based on the performance-based BFD sessions for each link of the primary TE-LSP and monitoring performance of the secondary TE-LSP based on the performance-based BFD sessions for each link of the secondary TE-LSP. The method may further include determining that the performance of the primary TE-LSP is degraded based on the monitoring of the performance of the primary TE-LSP and automatically switching a flow of data unit traffic from the primary TE-LSP to the secondary TE-LSP when the performance of the primary TE-LSP is degraded. |
