Improving performance of cluster-based secure application servers with user-level communication

In this paper, we have investigated the performance implications of SSL protocol for providing secure service in a cluster-based application server, and have proposed a backend forwarding scheme for improving server performance through better load balance. The proposed SSL/spl I.bar/with/spl I.bar/bf scheme exploits the underlying user-level communication minimizing the intra-cluster communication overhead. All results in this paper indicate that the proposed backend forwarding scheme is a viable mechanism for improving the performance of application servers in cluster-based data centers.
