Abstract: The number of releasable licenses is registered in a first entity, the resource to be used being attributed and/or having withdrawn from it, by a second entity, a releasable license for use which is registered in the second entity and/or a license. In a synchronization step the difference between the number of licenses allocated for use since a previous synchronization step and the licenses released again in this time is repeatedly reported from the second entities to the first entity respectively, this difference being taken as a basis for reducing or increasing the number of releasable licenses registered in the first entity, and conversely the resultant number of releasable licenses is reported from the first entity to the second entity and is registered there as the number of releasable licenses.

Abstract: A method is provided for data transmission between a first device and a second device via an IP-oriented network, wherein a security device is disposed between the first and the second device. In particular, data transmission between CORBA objects beyond one or more security devices is implemented by the invention wherein, when a message packet transmitted by the first device is received at the security device, it is ascertained with reference to a subcomponent of the received message packet whether the first device or the CORBA object running on the first device is released for data transmission via the security device.
