In response, the network node may propagate in the network fabric a message for advertising the network node as a candidate local source node at which to join the multicast group. The message for advertising may include data such as a reachability metric. The propagation of the message may be part of a flooding of such messages in the network fabric. The network node serving as the candidate local source node may thereafter “locally” join a host receiver device in the multicast group at the network node so that the device may receive the multicast traffic from the source node via the network node."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optimizing IP multicast delivery with use of local source nodes and the propagation of advertisements therefor","description":"In one illustrative example, a network node connected in a network fabric may identify that it is established as part of a multicast distribution tree for forwarding multicast traffic from a source no","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11509572","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.
