Further disclosed are a multi-domain routing computation device, a path computation element and a routing network. The present disclosure can improve greatly optimality of path computation and has a fairly high efficiency for the path computation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multi-domain routing computation method and device, path computation element and routing network","description":"Disclosed is a multi-domain routing computation method, including: when it is determined that there are two or more domains deployed with a Path Computation Elements (PCE) in a network, a routing path","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9712426","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.
