A Software Defined Networking (SDN) controller is configured to receive a request from a node related to a new TDM connection in the network; determine one or more routes in the network for the new TDM connection; determine match/action rules for the one or more routes at associated nodes of the one or more nodes; if the one or more routes include at least two routes, determine a group table at associated nodes of the one or more nodes to distinguish between the at least two routes; and provide the match/action rules and the group table to the associated nodes."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"OTN switching systems and methods using an SDN controller and match/action rules","description":"A method and network include receiving a Time Division Multiplexing (TDM) connection; determining information in overhead of the TDM connection; and if match/action rules defined by controller exist f","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9680588","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.
