The Service Availability Forum (SA Forum) was formed to foster an ecosystem as a building block for carrier-grade system development. It published a series of high availability specifications, commonly referred to as Application Interface Specification (AIS) and Hardware Platform Interface (HPI). In this paper, we try to evaluate recent implementation of the only one open source AIS-compliant middleware, OpenAIS, to see whether it satisfies the critical needs of failure impact in many carrier-grade applications. Our benchmark is conducted in two cases: processor leave and processor join, and evaluates several parameters crucial to the usefulness of the membership protocol. The result shows good performance for both cases. Finally we point out some possible directions to improve the worst-case time of OpenAIS.
