## Project history and usage

nuttcp is a command-line network throughput measurement tool for TCP and UDP. Its own manual places it in the lineage of ttcp and nttcp, while adding operational features such as server mode, rate limiting, multiple parallel streams, timed tests, IPv6, multicast, MSS, and TOS/DSCP support.

### Project history

The official manual traces the ancestry to Mike Muuss's pre-December-1984 ttcp work at BRL, then to an SGI-enhanced nttcp, and finally to nuttcp. That lineage explains the name and the tool's deliberately plain design: move buffers across a network path and report throughput plus timing, CPU, and UDP-loss data.

### Adoption history

nuttcp is niche but durable. Debian packages it as a network performance measurement tool across multiple architectures, Homebrew ships version 8.2.2, and ESnet Fasterdata documents it for high-speed UDP testing. Homebrew analytics on 2026-07-01 showed 158 installs over 365 days, which fits a specialist operations tool rather than a general developer CLI.

### How it is used

Network engineers use nuttcp in transmitter/receiver mode or the recommended client/server mode to test raw TCP or UDP throughput for a chosen duration or byte count. ESnet's examples show practical high-speed UDP testing with explicit packet size, test duration, UDP mode, window size, rate/report flags, and one-second interval output.

### Why package nerds care

For package maintainers, nuttcp is a classic small C networking utility: simple enough to package broadly, useful enough to keep around, and close to the metal when iperf-style testing needs a second opinion or UDP-specific behavior.

### Timeline

- Before 1984-12: ttcp is written by Mike Muuss at BRL, according to the nuttcp manual.
- Later: SGI's nttcp improves ttcp; nuttcp then extends nttcp with server mode, rate limiting, parallel streams, and timer-based usage.
- 2026-07-01: Homebrew lists nuttcp 8.2.2.
