Upon receiving a layer-3 multicast packet, the router node examines the multicast information to identify a set of child nodes registered for the corresponding multicast. The router node thereafter unicasts, at L2-level, the layer-3 multicast packet to each child node of the set of child nodes. In an embodiment, the router node participates in a routing protocol (e.g., RPL) to form a hierarchy of nodes constituting the wireless network, with the hierarchy containing a root node and a set of end devices as leaf nodes."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multicast packet delivery in a wireless network operating in non-storing mode","description":"A router node according to an aspect of the present disclosure maintains multicast information indicating child nodes registered for respective multicasts, while operating in a non-storing mode along ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9716984","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.
