Fault-tolerant broadcasts

Fault-Tolerant Broadcasts

A distributed program is presented that ensures delivery of a message to the functioning processors in a computer network, despite the fact that processors may fail at any time. All processor failures are assumed to be detected and to result in halting the offending processor. A reliable communications network is assumed.

Fault-Tolerant Broadcasts in CAN

Fault-tolerant distributed systems based on eld-buses may take advantage from reliable and atomic broadcast. There is a current belief that CAN native mechanisms provide atomic broadcast. In this paper, we dismiss this misconception, explaining how network errors may lead to: inconsistent message delivery; generation of message duplicates. These errors may occur when faults hit the last two bit...

Achieving Fault-Tolerant Ordered Broadcasts in CAN

The paper focuses on the problem to guarantee reliable and ordered message delivery to the operational sites of a CAN-Bus network. The contributions of the paper are firstly a hardware mechanism to handle rare failure situations and secondly, a protocol to guarantee the same order of messages on all nodes. After analyzing the error handling mechanism, we suggest a hardware extension to capture ...

A Modular Approach to Fault-tolerant Broadcasts and Related Problems

A New Design of Fault Tolerant Comparator

In this paper we have presented a new design of fault tolerant comparator with a fault free hot spare. The aim of this design is to achieve a low overhead of time and area in fault tolerant comparators. We have used hot standby technique to normal operation of the system without interrupting and dynamic recovery method in fault detection and correction. The circuit is divided to smaller modules...
