The Internet Engineering Task Force (IETF) reliable server pooling (RSerPool) group provides a protocol framework that supports server redundancy and session failover providing fault tolerance. The RSerPool protocol framework allows a pool of redundant information sources to be viewed as a single transport end point and is thereby able to provide persistent connections for end users. A performance evaluation of the RSerPool protocols show that early arriving registrars are disproportionately loaded as compared to late arriving registrars. This results in an unbalanced load across registrars and leads to performance degradation of the overall reliable server pooling system. In this paper, we propose a methodology based on the chord algorithm for balancing the load across all registrars. A performance evaluation is carried out to showcase the effectiveness of the algorithm.
