Research and Implement of Communication Middleware Based on Autonomous Decentralized System

The logical abstract structure and concept of autonomous decentralized system (ADS) middleware are introduced. A physical structure of ADS middleware with high reliability and fault-tolerant capacity is presented and the related key technologies are discussed in detail. In order to construct data-driven application system design technology, the normalized handle programming model supporting several kinds of communication methods and information mapping mechanism are proposed. For the implementation of online expansion and online maintenance, generalized mixed-queue model are provided. The three-stage survival signal confirmation algorithm and reliable multicast communication algorithm based on the publish/subscribe model are put forward for the realization of online fault-tolerant capacity. Though the construction of 10 nodes ADS, the characteristics of ADS were verified.
