<p>The present invention describes a method and an apparatus of multi-feature lookup process (steps 210-250) using multi-feature classification memory ('CM') 150. In one embodiment of the present invention, the method defines various features, offered in the router, into a feature hierarchy. Individual associated CMs are merged into a combined associated multi-feature CM 150. The feature rules for packet processing are merged according to the feature hierarchy and the multi-feature CM is populated with the merged rules. Multi-feature CM 150 includes combined packet-processing rules for multiple features. Multi-feature CM 150 eliminates the need for individual associated CMs. The memory space in multi-feature CM 150 is shared by various feature rules.</p> |
