Concurrent user license model

from Wikipedia, the free encyclopedia

In information technology, the concurrent user license model describes a form of licensing in which the maximum number of users who are allowed to access a resource at the same time is specified . A resource is, for example, a software application , a batch processor, a file or a workstation . The concurrent user licensing differs from the named user licensing model , in which the number of users is determined without a time reference. With the concurrent user license model, the software itself can be installed on any number of computers. A central server manages the licenses, which are also called floating licenses or network licenses . The server registers the number of currently issued licenses and grants every generally authorized user the right to use it. When all licenses have been granted, an additional competing user must wait until another user ends his session and a license is available again.

For example, while software with a license for five concurrent users can also be used by more than five users, only a maximum of five users can access it at the same time. Software with a license for five named users, on the other hand, can only be used by a maximum of five registered, named users.

Concurrent user licenses can be managed using license management software.
