A communicability test unit generates a test frame at every second period, transmits the test frame to the fabric card selected by a path selection unit, and receives the test frame returned from the fabric card. The second period is longer than the first period, and the communicability test unit evaluates the presence or absence of a fault based on the reception results for the first and second test frames."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Relay device","description":"A line card monitors communicability between itself and first to third fabric cards, and when there is abnormality in the communicability with the second fabric card, detects the abnormality and confi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9667567","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.
