The intent is to facilitate enhanced routing decisions based on this information in order to provide differentiated forwarding paths for specific packet flows. Software Defined Networking (SDN) places control of network elements (including all or some of their forwarding decisions) within external software components called controllers and orchestrators. This approach differs from conventional approaches that solely rely upon distributed routing protocols for the delivery of advanced connectivity services. By doing so, SDN aims to enable network elements to be simplified while still performing (some high level) forwarding function. This document examines the applicability of SDN techniques to Semantic Routing and provides considerations for the development of Semantic Routing solutions in the context of SDN.}, }
