High-Coverage Fault Tolerance in Real-Time Systems Based on Point-to-Point Communication
: The distributed recovery block (DRB) scheme is a widely applicable approach for realizing both hardware and software fault tolerance in real-time distributed and parallel computer systems. One of the most important extensions of the DRB scheme which were outlined in recent years but not developed fully is the integration of the DRB scheme and a network surveillance (NS) scheme. We recently developed an NS scheme effective in a variety of point-to-point networks and it is called the supervisor-based NS (SNS) scheme. In this paper, we present an integration of the DRB scheme with the SNS scheme, called the DRB/SNS scheme. This scheme is a significant improvement over the previous versions of the DRB scheme with respect to the fault coverage and recovery time bound achieved in the systems that are based on point-to-point networks. The execution support for the integrated scheme has been implemented as a part of the DREAM kernel prototype, a timeliness-guaranteed operating system kernel ...
