Abstract :
Many critical systems require high reliability and availability even when the systems are being maintained or upgraded. Soft System Bus (SSB) is the middleware for such systems. A conceptual architecture of SSB based on structured p2p network was proposed in our previous work. But, how high reliability and availability can be ensured was left unsolved. In this paper, we propose mechanisms to solve reliability and availability issues and analyze the effect of failures/arrivals of nodes on availability. Based on our solution, a SSB based system has been built in a simulated environment and the availability of SSB has been evaluated. Our results show that it is possible to achieve almost four nine availability in a reasonably dynamic environment assuring reliable delivery.
