The network nodes are layer-2 STP bridges. The apparatus includes, in the first network node, an egress filter timeout circuit that resets a timer in response to receiving the egress filter BPDU message, and a filter clear circuit that clears the egress filter to allow data packets to be sent from the egress port to the second network node in response to the timer reaching a timeout."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Energy efficient optimization for spanning tree protocol","description":"An apparatus for optimization for Spanning Tree Protocol (“STP”) data network includes an egress filter setting circuit in a first network node that sets an egress filter to discard data packets at an","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11240167","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.
