Abstract

Most of the highly available applications are built on top of expensive cluster software with proprietary application interface and have problems with maintenance and enhancements. The SA Forum has standardized application interface for building highly available applications. This paper discusses our experience with early adoption of SA Forum specification both for implementation of a cluster as well as developing a real-world telecom application. This paper outlines steps to develop highly available application on a SA Forum based cluster using an element of 3G networks, GGSN, as a case study. Various design considerations such as building standby; synchronizing between active and standby; and handling switchover are discussed in detail. In addition, we have included the lessons that we learnt during development, integration, and testing to help prospective developers of complex real-time telecom applications.
