Abstract

Fault tolerance is an important property of large-scale multi-agent systems as the failure rate grows with both the number of the hosts and deployed agents, and the duration of computation. Several approaches have been introduced to deal with some aspects of the fault-tolerance problem. However, most existing solutions are ad hoc. Thus, no existing multi-agent architecture or platform provides a fault-tolerance service that can be used to facilitate the design and implementation of reliable multi-agent systems. So, we have developed a fault-tolerant multi-agent platform (named DimaX). DimaX deals with fail-stop failures like bugs and/or breakdown machines. It brings fault-tolerance for multi-agent applications by using replication techniques. It is based on a replication framework (named DARX).
