A software license that is based on the number of simultaneous users accessing the program. It typically deals with software running in the server where users connect via the network. For example, in a five-user concurrent use license, after five users are logged on to the program, the sixth user is prohibited. When any one of the first five log out, the next person can log in. Concurrent licensing can be managed by the application itself or via independent software metering tools. See
software metering. Contrast with
per seat license.
