On the performance of reliable server pooling systems

Reliable server pooling (RSerPool) is a protocol framework for server redundancy and session failover, currently under standardization by the IETF RSerPool WG. While the basic ideas of RSerPool are not new, their combination into one architecture is. Some research into the performance of RSerPool for certain specific applications has been made, but a detailed, application-independent sensitivity analysis of the system parameters is still missing. The goal of this paper, after an application-independent, generic quantification of RSerPool systems and definition of performance metrics for both service provider and user, is to systematically investigate RSerPool's behavior on changes of workload and system parameters to give basic guidelines on designing efficient RSerPool systems
