A determination is made to discover if there is an alternative client-layer path to an established client-layer path between a first packet switching device and a second packet switching device if all server-layer resources of any particular server-layer SRLG of a plurality of total server-layer SRLGs associated with the established client-layer path become unavailable. In one embodiment, the plurality of total server-layer SRLGs includes: an SRLG of a same optical node, an SRLG of a same optical fiber, an SRLG of co-located plurality of optical nodes, and/or an SRLG of co-located plurality of optical fibers."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Server-layer shared link risk group analysis to identify potential client-layer network connectivity loss","description":"In one embodiment, a particular device within a client-layer network maintains client-layer topology information including server-layer Shared Risk Link Group (SRLG) information of server-layer device","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9634924","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.
