CommBench - FRAG


Description:

FRAG reads IP packet headers from the input and compares the packet length given in the header to the given fragment size. If a header represents a packet that is larger than the maximum fragment size, the header is replicated for each fragment. This requires the computation of and IP header checksum for each packet.

Input:

Sequence of IP headers. The IP headers are assumed to be the standard size of 20 bytes without options. The application comes with a generator program in $(CommBench)/frag/data/gen that creates a sequence of IP headers. The default input data is a sequence of 100,000 packets.

Notes:

The applications has a command line parameter '-f X', which defines the maximum fragment size. The smaller the fragment size is (relative to the average packet size), the more fragments are created.
