The node apparatus has a device that receives, from another node apparatus, a route control message which includes information required for route determination; a device that computes a route on the network based on the received route control message; a device that sends another node apparatus a route control message which includes information required for said another node apparatus to determine a route on the network; a device wherein when receiving the route control message, this device computes an operation start time for route control operation by the route computation and the message sending, based on a distance between a topology change part and said node apparatus of oneself; and a device that controls the execution of the route control operation based on the computed operation start time."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Node apparatus, route control method, route computation system, and route computation apparatus","description":"A node apparatus wherein when a topology change occurs on a network used for packet transfer between node apparatuses, the node apparatus performs dynamic route control for establishing a new normal r","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8493879","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.
