The Reliable Server Pooling (RSerPool) architecture is the
IETF's novel approach to standardize a light-weight protocol framework
for server redundancy and session failover. It combines ideas from different
research areas into a single, resource-ecient and unied architecture.
While there have already been a number of contributions on
the performance of RSerPool for its main tasks { pool management,
load distribution and failover handling { the robustness of the protocol
framework has not yet been evaluated against intentional attacks.
The rst goal of this paper is to provide a robustness analysis. In particular,
we would like to outline the attack bandwidth necessary for a
signicant impact on the service. Furthermore, we present and evaluate
our countermeasure approach to signicantly reduce the impact of
