Abstract: A communication network implements a Universal Measurement and Calibration Protocol (XCP) policy. The communication network includes a plurality of nodes, each of the nodes being operably connected to a bus to send and to receive data communications to and from others of the plurality of nodes. Certain of the data communications include a Universal Measurement and Calibration Protocol (XCP) identifier indicating the presence of XCP protocol within the data frame. At least one of the nodes is configured to mitigate identified XCP protocol in accordance with the policy.

Abstract: A system and method of regulating data communications between a vehicle electronics system and a computing device includes: communicatively linking a first data port of an isolation device with the vehicle electronics system; communicatively linking a second data port of the isolation device with the computing device; receiving data at the isolation device sent between the computing device and the vehicle electronics system; and permitting the data to pass through the isolation device based on the identity of the computing device, the rate at which the data passes through the isolation device, or the content of the data.
