A Rule Grouping Technique for Weight-Based TCAM coprocessors

Hao Che, Yong Wang, and Zhijun Wang


Abstract

A crucial issue associated with a TCAM coprocessor with weights is that no more rules can be enforced if the weights are exhausted. In this paper a rule grouping technique is proposed to solve this problem. The technique allows virtually unlimited number of rules with arbitrary rule structures to be enforced.
