Digest caches have been proposed as an effective method to speed up packet classification in network processors. In this paper, the authors show that the presence of a large number of small flows and a few large flows in the Internet has an adverse impact on the performance of these digest caches. In the Internet, a few large flows transfer a majority of the packets whereas the contribution of several small flows to the total number of packets transferred is small.
