Abstract: Methods, systems, and techniques for fault tolerant distributed computing. At least three fault tolerant messages are generated. The generating involves obtaining a first initial message identifier; mapping the initial message identifier to at least three different fault tolerant identifiers; and using the at least three different fault tolerant identifiers to identify the at least three fault tolerant messages. The at least three fault tolerant messages are then transmitted along at least one communication channel. The at least one communication channel may be a Controller Area Network (CAN) bus and the initial message identifier may be a CAN identifier.

Abstract: The present disclosure provides methods for detecting faults in a distributed computing network system. The method includes receiving, from a management services, authority information identifying peer computing devices of a distributed computing network system. For each respective peer computing device, a first message comprising a first instance of a dataset and a second message comprising a second instance of the dataset are received. Where the first peer computing device and the second peer computing device have authority over the data set, it is determined whether the first instance of the dataset matches the second instance of the dataset. Where the first instance of the dataset does not match the second instance of the dataset, a fault message is sent to the management services indicating that a fault has been detected at the first peer computing device.
