PACKET EXTRACTION OPTIMIZATION IN A NETWORK PROCESSOR |
摘要 |
A packet processor provides for rule matching of packets in a network architecture. The packet processor includes a lookup cluster complex having a number of lookup engines and respective on-chip memory units. The on-chip memory stores rules for matching against packet data. A lookup front-end receives lookup requests from a host, and processes these lookup requests to generate key requests for forwarding to the lookup engines. Based on information in the packet, the lookup front-end can optimize start times for sending key requests as a continuous stream with minimal delay. As a result of the rule matching, the lookup engine returns a response message indicating whether a match is found. |

1. A method of processing a packet comprising:
receiving a first segment of a packet; determining, based on the first segment, beats of a second segment of the packet containing portions of a key; determining a start time at which the key may begin to be forwarded as a continuous stream, the start time being based on a prediction of when the portions of the key in the second segment will be received; and initiating forwarding the key at the start time to a processing cluster configured to operate rule matching for the packet. |
