Castanet is enterprise solution software designed by Marimba Inc. (now BMC Software) to aid network administrators in data distribution by installing and updating applications across a computer network. Content is controlled with a transmitter running on a server.
Castanet compares old and new software package versions and sends required changes to each client machine.
Castanet uses separate channels (physical network transmission lines or broadcast signals) for each updated or installed application. Each client machine or network user receives the information with a desktop application, known as a tuner.
Castanet also functions as an extensible software inventory, subscription and reporting package that automates and simplifies enterprise software management.
