| 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. Each of the lookup engines receives a key request associated with a packet and determines a subset of the rules to match against the packet data. As a result of the rule matching, the lookup engine returns a response message indicating whether a match is found. | ||

| 主权项 | 1. A method comprising: receiving a request associated with a packet, the request including an identifier (ID); selecting at least one entry in a table indicated by the ID, the entry providing a starting address associated with a set of rules; determining a subset of rules based on at least one field of the request, the subset of rules being a portion of the set of rules; applying the at least one field against the subset of rules; and outputting a response signal indicating whether the at least one field matches at least one rule of the subset of rules. | ||
