Abstract:
In this paper, we present an efficient replication scheme designed to provide scalable and reliable group communication services for end system nodes that are widely dispersed in the network. This scheme is highlighted with three features. First, it employs both remote and neighbor replicas and intelligently avoids the services from interruptions while keeping replication cost low. Second, by using a tunable parameter, this scheme enables the nodes to adaptively make the most promising replica placement decision according to their specific network statuses. Third, a novel recovery technique is presented to minimize service recovery delay. The experimental results show that the proposed scheme is highly efficient in improving service reliability compared with existing neighbor-based replication scheme, random replication scheme and simple alternative schemes. The service recovery delay is greatly reduced by combining with the proposed recovery scheme.
