The communication system, upon implementing a broadcast-type multicast service, enhances compensation of communication breaks when detecting and recovering from a fault in an IP network, and reduces the network traffic."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Communication system, delay insertion server, backup server and communication control apparatus","description":"A communication system includes a probe transmission server 3 which transmits at fixed intervals of time a probe multicast packet distributed along the same path as a main multicast packet, a delay in","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8462620","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.
