System for dynamic stream management in audio video bridged networks

A network communication system includes one or more talkers that may communicate data streams to one or more listeners over a network, such as an Ethernet Audio / Video Bridging network. Before transmitting a new data stream, a talker may request a reservation for bandwidth through a controller that is configured to manage and / or control the flow of data streams over the network. If there is not enough bandwidth, then the controller may determine whether any existing data streams may be transmitted at lower bandwidths to make available enough bandwidth for the new data stream. Alternatively, the controller may determine whether any existing data streams having lower priorities than the new data stream may be terminated to make available enough bandwidth for the new data stream.

Limp-Home Operation of Audio Video Bridging Networks

Electronic modules in a vehicle may communicate over an Audio / Video Bridging (AVB) network. The modules normally cooperate to send and receive streams of data with a specified quality of service as AVB streams. When conditions are present in which an AVB-quality stream cannot be sent over the network, the modules can communicate with certain limp-home functionality. Sending modules may send streams of data without a stream reservation as multicast messages. Receiving modules may be configured to receive the multicast messages. Network bridge modules may be configured to enable a Talker Pruning feature to facilitate handling of the multicast messages.
