CAMs are the most popular practical method for implementing packet classification in high performance routers. Their principal drawbacks are high power consumption and inefficient representation of filters with port ranges. A recent paper  showed how partitioned TCAMs can be used to implement IP route lookup with dramatically lower power consumption. We extend the ideas in  to address the more challenging problem of general packet classification. We describe two extensions to thedoi:10.1109/icnp.2003.1249762 dblp:conf/icnp/SpitznagelTT03 fatcat:fk4s5q7wzra7haz7jyjsz4nzwe
