The header space analysis allows near-real-time validation that packet transport flows in an Multiprotocol Label Switching-Transport Profile (MPLS-TP) network have been correctly programmed on the switches by a Software Defined Networking (SDN) controller or other technique such that the correct label mappings have been made to carry a flow from a source to a destination, and all flows from any source to a destination are isolated from one another."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Header space analysis extension systems and methods for transport networks","description":"A method for validation of a packet transport network includes performing a header space analysis, with input headers to obtain output headers from the header space analysis, between one or more ingre","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9819579","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.
