Abstract
A packet classifier for a network and the method thereof are provided. The packet classifier includes at least one content locator and one matching engine. Each of the content locators performs at least one location operation. Each of the location operations outputs the sum of at least one accumulation item as an output offset. Each of the accumulation items is generated according to at least one content locator system parameter and/or the content data of a network packet. One of the accumulation items is a base value, and the base value is an offset defined by system parameters or the output offset of a location operations of one of the content locators. The output offset of the last location operation of one of the content locators is the location of a matching field of the network packet. This location is provided to the matching engine for a data matching operation.
