EVALUATING THE PERFORMANCE OF AN AUTOMOTIVE SWITCH NETWORK

摘要

A diagnostic device and interface is connected to an automotive switch fabric network, comprising of a plurality of communication nodes, through one of the nodes in the switch fabric network. The diagnostic device and interface configures the switch fabric network to operate in a test mode. The diagnostic device and interface issues a first command to one node to start traffic across a test node and a second command to another node to generate a test message that passes through the test node. The test node contains message processing logic that processes the messages as they pass through the test node. A plurality of timestamps is generated in the message processing logic of the test node to monitor the progression of the messages through the processing logic. The test node includes a diagnostic interface agent that collects timestamp data and reports the data to the diagnostic interface and device.
