When receiving link information from another area assigned a different level, the communication apparatus determines whether the received link information is new link information newer than link information stored in a predetermined storage unit; when it is determined that the received link information is new link-information, the communication apparatus stores the new link information into the predetermined storage unit and advertises it in its own area; by contrast, when it is determined that the received link information is not new link-information, the communication apparatus discards the received link information without storing and advertising."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Communication apparatus","description":"A communication apparatus stores therein link information indicating a network connection status of an entire hierarchical network, collects link information indicating a network connection status in ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8520690","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.
