Efficient Protocols for Fail-silent Nodes in Distributed Systems

Lookup NU author(s): Dr Paul EzhilchelvanORCiD, Emeritus Professor Santosh Shrivastava, Dr Neil Speirs



A fail-silent node is composed of a number of "fail-arbitrary" conventional processors on which application level processes are replicated to achieve fault-tolerance. The non-faulty processors of a node need to execute agreement and order protocols to 'keep in step'. The design and the implementation of efficient protocols for a two processor fail-silent node are described in detail. In particular we introduce two new ordering protocols which substantially enhance the performance of the node.
