Bandwidth represents the capacity of the connection. The greater the capacity, the more likely that greater performance will follow, though overall performance also depends on other factors, such as latency.
BandwidthD tracks usage of TCP/IP network subnets and builds html files with graphs to display utilization. Charts are built by individual IPs, and by default display utilization over 2 day, 8 day, 40 day, and 400 day periods. Furthermore, each ip address's utilization can be logged out at intervals of 3.3 minutes, 10 minutes, 1 hour or 12 hours in cdf format, or to a backend database server. HTTP, TCP, UDP, ICMP, VPN, and P2P traffic are color coded.

bwbar is a small C-based program for Linux-based machines which produces bandwidth usage statistics for a network interface. It was originally written by H. Peter Anvin, and I (Brian Towne) modified it somewhat to better suit my needs. The original program was released under the GPL. A number of people have asked for the modified program and its source, so I have created this page.

ipband is a pcap based IP traffic monitor. It tallies per-subnet traffic and bandwidth usage and starts detailed logging if specified threshold for the specific subnet is exceeded. If traffic has been high for a certain period of time, the report for that subnet is generated which can be appended to a file or e-mailed. When bandwidth usage drops below the threshold, detailed logging for the subnet is stopped and memory is freed.

NetPIPE is a protocol independent performance tool that visually represents the network performance under a variety of
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 ).

tcpflow is a program that captures data transmitted as part of TCP connections (flows), and stores the data in a way
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.
