METHOD FOR LICENCE ALLOCATION AND MANAGEMENT

摘要

The invention relates to a method for allocation and management of a usage permit for software in a computer network (1), comprising at least one server (2) and several clients (3.1, 3.2, 3.3, 3.4, 3.5), whereby the software may be called up by several or all clients (3.1, 3.2, 3.3, 3.4, 3.5). The use of the installed software is only permitted in the clients (3.1, 3.2, 3.3, 3.4, 3.5) during the period of validity of a usage permit requested from the server (2), whereby clients (3.1, 3.2, 3.3, 3.4, 3.5) communicate with the server (2) by means of a network connection (5), at least for the permit request. Usage permits are allocated by the server (2) according to conditions of a network license (6, 4.1, 4.2, 4.3) which either relates to a permit for simultaneous use of the software by an agreed maximum number (for example three) of clients (3.1, 3.2, 3.3, 3.4, 3.5) for an agreed total duration (D) of software use. The allocation of a use permit by the user is achieved by means of a token which authorises a use of the software in the corresponding client (for example 3.1), said usage permit expiring on return of the token or on expiry of a validity period for the token.
