The Reliable Server Pooling (RSerPool) architecture is the IETF's new standard for a lightweight server redundancy and session failover framework to support availability-critical applications. RSerPool combines the ideas from different research areas into a single, resource-efficient and unified architecture. Server pools are maintained by redundant management components, which are called registrars. Registrars monitor the availability of servers in the pool and remove them in case of failure. Furthermore, they synchronize their view of the pool with other registrars to provide information redundancy.In this paper, we first analyze the implications of registrar redundancy on the server pool performance. Furthermore, we present an optimization approach for the server pool management, which improves the system performance in case of registrar problems by hardware failures or Denial of Service attacks.
