Abstract: The present disclosure describes techniques for hardware acceleration for routing programs. In some aspects communications between a routing determination program and a packet router are monitored in a router, both the routing determination program and the packet router being part of a software layer of the router. The communications include the routing determination program providing configuration data to the packet router. Based on the monitored communications, a packet processor is changed to reflect the configuration data, the packet processor being part of a hardware layer of the router. The packet processor performs packet routing operations of receiving packets, determining the next routers in the paths to the target destinations of the packets, and sending the packets to the next routers independent of the software layer.
