An electronic device for executing an application includes: application data, a central control unit for processing the application data according to a first method call, an interface for transmitting a description of the first method call to a second electronic device, and a synchronization entity for generating the description and passing the description to the interface. The transmitted description is used by the second electronic device to derive a second method call that is executable on the second electronic device.

Processing application data

The invention relates to a method for operating virtual networks. The method comprises providing a first virtual network comprising a first set of network ports assigned to a first virtualization tag (T) and a second virtual network comprising a second set of network ports assigned to a second virtualization tag (T), the first and the second virtual network having compatible address ranges and being adapted to only pass data packets within them, providing a first network node having a source address (SA) in the first virtual network and being operationally connected to a first port (P) assigned to the first virtual network by means of the first virtualization tag (T), monitoring the first network node in order to detect a predetermined condition, and, on detection of the predetermined condition, reassigning the first port (P) to the second virtual network by means of assigning the second virtualization tag (T) to the first port (P), such that no data packet can be passed from the first network node (N) to a second network node (N) connected to a second port (P) assigned to the first virtual network by means of the first virtualization tag (T) directly and keeping of the source address (SA) for the first network node (N) in the second virtual network (). The invention further relates to a further method for operation virtual networks, a data network system and a computer program product adapted to perform the inventive methods.

Methods for operating virtual networks, data network system, computer program and computer program product

The invention is directed to a method of making communication or information services via a telecommunication network available to service users. The method entails receiving from agent initiators registrations for service offer references, receiving from a service provider for a service a service offer notification comprising a service offer reference, making available to those agent initiators who have registered themselves under the received service offer reference, the service offer notification, which is usable for obtaining a service agent for the service, and in the case of initiation of the service agent, receiving from the service agent at least one registration for a service subscription reference, receiving from the service users service subscription notifications, comprising a service subscription reference, making available to those service agents who have registered themselves under the received service subscription reference, the service subscription notification, which is at least in part usable as input for the service agent for the service.
