Abstract :
Improving the availability of services of is a key issue for survivability of a cluster system. Lots of schemes are proposed for this purpose. But most of them aim at enhancing only the service-level availability or application specific. In this paper, we propose a scheme called High Availability with Redundant TCP Stacks (HARTs), providing connection-level availability by exploring the redundant TCP stacks for TCP connections at the server side. We present our performance experiment results on our HA cluster prototype. From results, we find the configuration of one primary server with one backup server running on separated 100 Mbps Ethernet has acceptable performance to support the server side applications while delivering high availability.
