摘　　要：提出一种适合于紧要时间通信的实时多路访问算法，其基本设计思想是将控制访问的策略集成到争用型ＣＳＭＡ算法中，整个算法交替工作在预约期和争用期两个阶段。算法分析和仿真结果表明，实时多路访问算法不仅能够保证满足系统中所有紧要时间报文的死线要求。This paper presents a real-time multi-access algorithm suitable for time-critical communications. The basic designing idea of the algorithm is to integrate a controlled access scheme into a contention-based CSMA algorithm. The algorithm operates by alternating a reservation phase and a contention phase. The algorithm analysis and simulation results indicate that our algorithm does not only guarantee all time-critical messages in the system to meet their deadlines, but maintain high efficiency as well.
