Abstract:
A method for processing frames in a network processing system, said method comprising:receiving a frame at an input to said network processing system; constructing a key in conformance with information contained in said received frame; searching a dynamic classifier tree for a dynamic tree leaf containing a pattern that matches said constructed key; in response to said dynamic tree leaf being found within said dynamic classifier tree, processing said received frame according to a first rule contained within said dynamic tree leaf, setting an inhibit indication for preventing a static tree leaf from causing performance of a duplicate set of actions associated with said dynamic tree leaf; and in response to said dynamic tree leaf not being found within said dynamic classifier tree, searching a static classifier to find a static tree leaf containing a pattern that matches said key and processing said received frame according to a second rule contained within said static tree leaf only if said inhibit indication is not set.
