Abstract
Systems and methods for accelerating computer network policy searching are provided. According to one embodiment, a packet is received by a policy search engine (PSE) of a packet processing device. A set of candidate policies are identified from among multiple policies of the packet processing device by screening the multiple policies by a speculation unit of the PSE based on metadata associated with the received packet. Finally, a matching policy for the received packet is identified by a policy search processor (PSP) of the PSE by executing policy-search-specific instructions and general purpose instructions.
