In certain embodiments, these techniques include receiving, at a network device from a software-defined networking (SDN) controller, flow entries for installation into flow tables of the network device, where the flow entries are structured in a manner that assumes the flow tables can be looked-up serially by a packet processor of the network device, but where the flow tables are implemented using hardware lookup tables (e.g., TCAMs) that can only be looked-up in parallel by the packet processor. The techniques further include converting, by the network device, the received flow entries into a format that enables the packet processor to process ingress network traffic correctly using the flow entries, despite the packet processor's parallel lookup architecture, and installing the converted flow entries into the flow tables/hardware lookup tables."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Implementing multi-table OpenFlow using a parallel hardware table lookup architecture","description":"Techniques for implementing multi-table OpenFlow using a parallel hardware table lookup architecture are provided.
