The method includes, converting, by a relay, a known-answer service query packet that is sent by a user terminal and used to query service information in an mDNS, into a unicast known-answer service query packet and sending the unicast known-answer service query packet to a gateway, receiving, by the relay, a unicast known-answer service answer packet that is sent by the gateway and includes service information unknown to the user terminal, and converting, by the relay, the unicast known-answer service answer packet into a multicast known-answer service answer packet and sending the multicast known-answer service answer packet to the user terminal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Packet transmission method, apparatus, and system in multicast domain name system","description":"A packet transmission method, apparatus, and system in a multicast domain name system (mDNS), which are used to resolve a network bandwidth waste problem due to much service information needs to be tr","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9774563","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.
