An architecture with reliability support for wide-area distributed applications

As the platform for wide-area distributed applications, the middleware architecture should support high reliability. However, current solutions cannot meet this requirement. Therefore, MSWADA, a new architecture designed for large-scale distributed applications, is presented in this paper. It can meet reliability while not injuring adaptability. This paper addresses the problem of how MSWADA supports three levels of reliable services: basic, FIFO and safe.
