Abstract
A method, apparatus and computer program product for performing TCAM lookups in multi-threaded packet processors is presented. A Ternary Content Addressable Memory (TCAM) key is constructed for a packet and a Packet Reference Number (PRN) is generated. The TCAM key and the packet are tagged with the PRN. The TCAM key and the PRN are sent to a TCAM and in parallel the packet and the PRN are sent to a packet processing thread. The PRN is used to read the TCAM result when it is ready.
