By means of the technical solutions of the disclosure, it is possible to shorten significantly recovery time of a backup port, and improve greatly performance of link recovery."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fast recovery method and device for STP-based backup port","description":"Disclosed is a fast recovery method for a Spanning Tree Protocol (STP) based backup port, and the method includes: it is detected that a failure occurs on a port of an STP-based device; and it is dete","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9806990","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.
