摘要：For internet servers, how to handle colossal data volumes and maintain data consistency is a major challenge. To ensure each database maintains the latest information and messages do not conflict with one another, we have a new type of database NoSQL (Not Only SQL). A number of atomic broadcast protocols, including libPaxos, Mencius and RingPaxos, have been established to help maintain transmission consistency for cloud computing services. This paper introduces a new atomic broadcast protocol to improve the performance of existing protocols. Our new protocol divides the network topology into various areas to process messages in a distributed way and uses a rotating mechanism to effectively balance the server loads. Experimental evaluation has been conducted to compare the performance of different protocols. The results show that our new protocol yields higher throughput and lower latency under different client loads in contrast to other protocols
