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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Health probing detection and enhancement for traffic engineering label switched paths","description":"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 (","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8503293","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
