Abstract
A method and apparatus for classifying packets, e.g., at wire speed are disclosed. The method receives a packet and processes the packet through a hardware-based packet classifier having at least one evolving rule. The method then processes the packet through a software-based packet classifier if the hardware-based packet classifier is unable to classify the packet. In one embodiment, the at least one evolving rule is continuously modified in accordance with learned traffic characteristics of the received packets.
