摘要: A reliable distributed systems architecture composed of fail-silent nodes connected by redundant networks is developed. node constructed replicating the computations on two distinct and dedicated processors which check each other’s performance to form a self-checking processor pair. Given that no more than one in fails, guaranteed either function correctly or effectively stop functioning. High availability system services can be obtained application level processes nodes. Managing general, replicated particular, require group communication (multicast communication) services. The paper presents an integrated suit protocols for performing multicasts, illustrates how dual redundancy exploited implementing these protocols.
