Method and system for classifying packets in a network based on meta rules

摘要

In one embodiment, a packet in a network is classified. A header of the packet includes various fields. Single-dimensional lookups are performed for each header field, based on a plurality of packet-classification rules. The results obtained from the single-dimensional lookups are merged to obtain a Resultant Bit Vector (RBV). Thereafter, the RBV is processed using a Finite State Machine (FSM), based on the plurality of packet-classification rules.
