RSerPool - providing highly available services using unreliable servers

The Reliable Server Pooling (RSerPool) protocol suite currently under standardization by the IETF is designed to build systems providing highly available services by mechanisms and protocols for establishing, configuring, accessing and monitoring pools of server resources. Using RSerPool, critical infrastructure services like SS7 telecommunication systems, e-commerce transaction processing or distributed computing can be provided highly available using pools of unreliable servers. In this paper, we first give an overview of the RSerPool framework. In the following, we quantitatively show performance impacts of varying RSerPool parameters to failover handling, server selection efficiency and overhead traffic under server failure conditions.
