Abstract: A method includes: obtaining, by a control device, a service requirement latency of transmitting a data stream from a first network device to a second network device; obtaining, by the control device, a network device transmission latency on a forwarding path and a link transmission latency on the forwarding path; and determining, by the control device based on the service requirement latency of the data stream and the network device transmission latency and the link transmission latency on the path for forwarding the data stream, a required bandwidth for transmitting the data stream.

Abstract: A communication network, comprising a video server, adapted to generate a multicast video signal, and a first router is provided. The communication network is operated by a first communication provider. The first router is adapted to receive the multicast video signal, generate a plurality of unicast video signals from the multicast video signal, and provide each of the plurality of unicast video signals to one of a plurality of user devices, connected to a first further communication network, through at least a first further router, which is part of the first further communication network. The first further communication network is operated by a second communication provider.
