When the Proxy Forwarding node receives traffic targeting the failed neighboring node, the Proxy Forwarding node performs SR proxy forwarding for the failed neighboring node by forwarding the traffic towards a destination of the traffic in a direction that avoids the failed neighboring node for a period of time after the IGP has converged."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Interior gateway protocol (IGP) for segment routing (SR) proxy segment identifiers (SIDS)","description":"A Proxy Forwarding node configured to advertise Segment Routing (SR) proxy forwarding capability of the Proxy Forwarding node for neighboring nodes of the Proxy Forwarding node using extensions to int","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11516111","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.
