The function chain network controller discovers FBCS capable nodes and their topology, and maintains a function chain substitution state and distributes it to the FBCS relevant substitutions. The function chain network controller distributes a list of adjacent FBCSs to the FBCS, and distributes a list of abstracted adjacent FBCSs to the FBCS and translates requests from an abstracted value to a real value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method to optimize flow-based network function chaining","description":"In a forwarding network comprising a function chain network controller, a plurality of intermediate network functions (NFs) and flow-based chain selectors (FBCSs) forming VNFs and configured to transf","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9825858","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.
