TCP-ABC: From multiple TCP connections to atomic broadcasting

Abstract

In this paper, we propose a novel scheme, named as TCP-ABC, which replicates the server side TCP connections among multiple server nodes of a cluster. By guaranteeing atomic request delivery, and consensus on responses, this scheme provides the legacy server applications running on the server nodes with multiple active backups in a transparent fashion. By failing the connections over healthy units, the scheme enhances the service and data availability of the cluster, By conducting experiments on the prototype system of a cluster up to four nodes, we find TCP-ABC results in small performance lost while greatly enhances the service and data availability. © IFIP International Federation for Information Processing 2005.
