That is, in response to a connectivity disruption in a portion of underlying optical transport ring, one or more optical devices within the optical transport ring are modified such that packets between at least a portion of the leaf devices are rerouted along optical paths between at least two of the spine network devices."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Data center packet optical transport failure protection","description":"In response to a connectivity disruption in an underlying optical transport ring supporting a routing and packet switching topology, one or more of optical devices of the optical transport ring are mo","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10469921","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.
