As such, the switch may determine whether the solicited node multicast address is a hit or miss within a switch hardware table of the switch, and in response to a hit, re-writes the destination MAC address with a known value of the destination target from the table, and unicasts the packet to the destination target. In one or more additional embodiments, in response to a miss, and in response to a single-switch architecture, the switch drops the packet, while in response to a miss, and in response to a multi-switch architecture, the switch may compute a repository switch for the solicited multicast destination, and unicasts the packet to the computed repository switch."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"IPV6/IPV4 resolution-less forwarding up to a destination","description":"In one embodiment, a switch in a computer network intercepts a packet to a destination target, the packet having a solicited node multicast address of the target as a destination media access control ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9621581","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.
