Abstract
A fault tolerant data processing network includes a number of nodes intercoupled through an interconnect circuit. The micro-architectures of the nodes are configured for sending and receiving messages via the interconnect circuit. In operation, a first Request Node sends a read request to a Home Node. In response, the Home Node initiates transmission of the requested data to the first Request Node. When the first Request Node detects that a fault has occurred, it sends a negative-acknowledgement message to the first Home Node. In response, the Home Node again initiates transmission of the requested data to the first Request Node. The requested data may be transmitted from a local cache of a second Request Node or transmitted by a Slave Node after being retrieved from a memory. The data may be transmitted to the first Request Node via the Home Node or directly via the interconnect.
