Enhancing Fault Tolerance And Reliability In GAIAOS Through Structured Overlay Network

Abstract

GAIAOS event manager is a distributed event service, based on CORBA event service with a centralized entry point, resulting in limited fault resilience and scalability. In this paper, we have proposed a decentralized event service for GAIAOS through the use of DHT based structured overlay network to overcome these problems. The proposed architecture provides a completely distributed event communication mechanism without any centralized entry point. Incorporation of the structured overlay network in GAIAOS results in higher degree of fault resilience and scalability
