Abstract:
1. A method, comprising: controlling an on-demand-service between a first and a second end device by using a first protocol, a first protocol message having a destination address indicating the first or the second end device, wherein controlling comprises managing bandwidth; selecting a correct first end device among at least two first end devices during service set-up; causing delivery of the service to a second end device from the correct first end device in a service stream via a network; receiving first protocol messages separated from other traffic received from the network; controlling the service stream in the transmitting network by using the separated first protocol messages; causing the first protocol messages used in controlling the service stream to be forwarded towards the respective destination addresses of the messages; causing traffic other than the first protocol message to pass toward the respective destination address; recognizing the first protocol message relating to on-demand-service stream set-up; determining requested resources indicated in the first protocol message; determining resources available in the network; allocating network resources to the on-demand-service stream based on the requested and available resources; and modifying the requested network resources indicated in the first protocol message before forwarding the message, when the allocated resources are not the same as the requested resources.
