history
Project history and usage
rmcast packages RML, the Reliable Multicast Library, a free software library for reliable data transmission over IP multicast.
Project history
The official archived project page explains that IP multicast saves bandwidth by sending one packet across each physical link, but that UDP-based multicast lacks reliability. RML was developed to provide a reliable multicast environment and was distributed under the QPL.
Adoption history
The project appears to have been a niche academic and systems-networking library rather than a broad user-facing tool. Homebrew packaging keeps the library and the `mcastproxy` and `rmchat` executables installable for legacy multicast experiments.
How it is used
Package-level usage centers on the reliable multicast library and the shipped command-line programs `mcastproxy` and `rmchat`; the official project page says the release tarballs included a manual.
Why package nerds care
rmcast is notable to package maintainers as a preserved multicast library with old release tarballs, bundled manual material, and QPL licensing. It represents the kind of specialized networking code that survives mostly through Unix package collections.
