Replication has become a central element in modem information systems playing a dual role: increase availability and enhance scalability. Unfortunately, most existing protocols increase availability at the cost of scalability; This paper presents architecture, implementation and performance of a middleware based replication tool that provides both availability and better scalability than existing systems. Main characteristics are the usage of specialized broadcast primitives and efficient data propagation.
