developed and supported by Nevil Brownlee at the University of Auckland. Nevil also developed a version of NeTraMet
which uses the CoralReef library to read packet headers. This ‘CoralReef NeTraMet meter’ can work with any CoralReef
data source; it has been tested on both CAIDA and NLANR trace files, and on DAG and Apptel ATM interface cards.
conditions. It performs simple ping-pong tests, bouncing messages of increasing size between two processes, whether
across a network or within an SMP system. Message sizes are chosen at regular intervals, and with slight perturbations, to provide a complete test of the communication system. Each data point involves many ping-pong tests to provide an accurate timing. Latencies are calculated by dividing the round trip time in half for small messages ( <64 Bytes ).
(aka unidirectional) data transfer and request/response performance using either TCP or UDP and the Berkeley Sockets interface. As of this writing, the tests available either unconditionally or conditionally
that is convenient for protocol analysis or debugging. A program like tcpdump shows a summary of packets seen on the
wire, but usually doesn’t store the data that’s actually being transmitted. In contrast, tcpflow reconstructs the actual data streams and stores each flow in a separate file for later analysis. tcpflow understands TCP sequence numbers and will correctly reconstruct data streams regardless of retransmissions or out-of-order delivery.
