A bidirectional forwarding detection (BFD) data packet is encapsulated in the VXLAN data packet to provide a VXLAN BFD data packet. The VXLAN BFD data packet is transmitted to a terminating VTEP to establish a BFD session over a VXLAN tunnel. A communication status of the VXLAN tunnel is determined for the BFD session based on a reply BFD data packet received from the terminating VTEP in accordance with a receiving time interval."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Bidirectional forwarding detection over a virtual extensible local area network","description":"A system and method for detecting a communication status includes generating, at an originating virtual tunnel end point (VTEP), a virtual extensible local area network (VXLAN) data packet in accordan","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9819511","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.
