Abstract
A vehicle network node module includes device buffers, a network buffer, a switch circuit, and a processing module. The device buffers temporarily store outgoing device packets from, and temporarily store incoming device packets for, vehicle devices in accordance with a locally managed prioritization scheme. The network buffer receives incoming network packets from, and outputs the outgoing network packets to, a vehicle network fabric in accordance with a global vehicle network protocol. The network buffer also temporarily stores the incoming network packets and the outgoing network packets in accordance with the locally managed prioritization scheme. The switching circuit selectively couples the network buffer to individual ones of the device buffers in accordance with the locally managed prioritization scheme. The processing module interprets the outgoing device packets and the incoming network packets to determine types of packets and determines the locally managed prioritization scheme based on the types of packets.
