Improving Fault Tolerance Mechanisms Implemented by WADE Platform
Brice X. R. Hessou · 2013
Problems related to scalability, reliability, protection of privacy and energy consumption have led to the development of distributed architectures for the workflows execution including WADE platform (Workflows and Agents Development Environment). However, further problems remain, such as those related to network connectivity. It has therefore become necessary to make these architectures fault tolerant. In this paper, we improved fault tolerance mechanisms implemented by WADE platform which is an agent-based workflow engine. To solve the problems of scalability and maintainability of the platform revealed by fault tolerance mechanisms implemented by WADE, we proposed an additional functionality based on the distributed storage concept of Chord protocol. Unlike existing mechanisms, our proposal has helped to restart all agents of a container which has suddenly died.
