Method and system for a centralized vehicular electronics system utilizing ethernet with audio video bridging
First Claim
1. A method for networking, the method comprising:
- directly coupling first audio video bridging enabled equipment to each electronic device within a first group of two or more electronic devices in a vehicle via respective first Ethernet links;
directly coupling second audio video bridging enabled equipment to each electronic device within a second group of two or more electronic devices in the vehicle via respective second Ethernet links;
coupling said first audio video bridging equipment to said second audio video bridging equipment via one or more third Ethernet links; and
reserving resources on said one or more third Ethernet links utilizing said first and second audio video bridging equipment to enable information to be communicated between a first electronic device in the first group and a second electronic device in the second group and to give priority to mission critical electronic devices over non-mission critical electronic devices, at least one of said first and second groups including a mission critical electronic device, said mission critical electronic devices transmitting diagnostic information.

Abstract
Aspects of a method and system for a centralized vehicular electronics system utilizing Ethernet with audio video bridging are provided. In this regard, electronic devices in a vehicle may be communicatively coupled via one or more Ethernet links and information may be communicated between the electronic devices over the Ethernet link(s) utilizing audio video bridging. At least one of multimedia, control, diagnostic, and sensory information between the electronic devices. Accordingly, resources on the one or more Ethernet links may be reserved via AVB to give priority to one of multimedia, control, diagnostic, and sensory information. Information communicated between the devices may be secured utilizing MACsec and related protocols. The electronic devices may comprise two or more network ports and may be enabled to forward packets between the two or more ports. The Ethernet links may comprise optical and/or copper cabling.
