Communication system using audio video bridging

A computer program product, comprising:

• a non-transitory computer readable medium for a first electronic control unit (ECU), comprising one or more software programs stored on the computer readable medium having program instructions that include:
• determining a throughput parameter associated with a reserved traffic channel operating in accordance with an audio video bridging (AVB) protocol, wherein the reserved traffic channel is between the first ECU and one or more endpoint ECUs;
• providing audio-video (AV) data via the reserved traffic channel using the throughput parameter;
• receiving an indication using the AVB protocol or a secondary protocol, different than the AVB protocol, of a change in throughput demand on the reserved traffic channel;
• determining a new throughput parameter based on the indication;
• and
• providing AV data via the reserved traffic channel using the new throughput parameter.

A method of shaping high priority traffic using an audio video bridging (AVB) protocol, comprising the steps of:

• reserving a traffic channel having a bandwidth based on a volume of network traffic, wherein the reservation is according to the AVB protocol for communication of high priority data between a first electronic control unit (ECU) and a second ECU;
• providing high priority data over the reserved traffic channel;
• determining a change in the volume of network traffic based on data received at the first ECU via the AVB protocol or a second protocol, wherein the second protocol is different than the AVB protocol;
• based on the change, re-determining reserved traffic channel;
• and
• providing high priority data over the re-determined, reserved traffic channel.
