CommBench - TCP

Description:

TCP is the tcpdump-3.4 application developed by the Network Research Group at Lawrence Berkeley National Laboratory. It uses the libpcap-0.4 package to capture packets. It then compares header fields to a specified pattern.

Input:

A packet trace generated by tcpdump ('-w' option). The default file contains 101043 packets.

Notes:

The filter is chosen such that is does not match any packet only in the least significant number of bits. This way, most of the pattern has to be compared before a non-match can be detected.
