Abstract :
We propose an indexed TCAM architecture, PC-TRIO, for packet classifiers. PC-TRIO uses wide SRAMs and index TCAMs. On our classifier datasets, PC-TRIO on an average reduced TCAM power by 96% and lookup time by 98%, compared to PC-DUOS+ [23] that does not use indexing or wide SRAMs. We extend PC-DUOS+ by augmenting it with wide SRAMs and index TCAMs using the same methodology as used in PC-TRIO, to obtain PC-DUOS+W. On ACL datasets, PC-DUOS+W reduced TCAM power by 86% and lookup time by 98%, compared to PC-DUOS+.
