Abstract: A gateway device between a first and second communication network outside the gateway device handles communication between a first device in the first network and a second device in the second network. When the gateway receives a communication request from the first device, directed to the second device, for performing a first cryptographic data communication protocol, the gateway determines whether the first cryptographic data communication protocol is registered as unsafe in the gateway device, and/or registered as safe, in particular whether it is safe against key reconstruction by a quantum computer. When the first cryptographic data communication protocol is not registered as unsafe in the gateway device, and/or registered as safe, the gateway device forwards messages exchanged as part of execution of the first cryptographic data communication protocol between the first and second device.

Abstract: Stream control methods and devices are provided for use in a network for transferring a video stream from a video server to a video client via a distribution chain of network resources. A streaming controller controls streaming settings at the client node. A bridge controls the video stream by obtaining a bandwidth requirement of the video stream, and network resource data including bandwidths available on network resources. The bridge determines a resource allocation including an allocated bandwidth, based on the network resource data and the bandwidth requirement so that the video stream complies with the network resource data. The allocated bandwidth enables the streaming controller to control, in accordance with the allocated bandwidth, the streaming settings for the client. A network controller receives network control data from the bridge to control, in accordance with the allocated bandwidth, the respective distribution chain associated to the respective video stream.
