以哈尔滨科学技术大学命名的环形网——HUSTRING在媒介访问控制方式上采用了令牌传递和寄存器插入相结合的技术。理论分析和计算机仿真的结果表明,这种网络的实时传输性能明显地优于著名的令牌环局域网。本文描述了HUSTRING的网络拓扑、物理层、媒介访问控制层和逻辑链路层的体系结构,介绍了它的环接口的组成,并且比较了它与令牌环的实时性能。 The ring network named by Harbin University of Science and Technology - HERMING uses a combination of token passing and register insertion in media access control. Theoretical analysis and computer simulation results show that the real-time transmission performance of this network is obviously better than the famous Token Ring LAN. This article describes the architecture of HUSTRING’s network topology, the physical layer, the medium access control layer, and the logical link layer, describes the composition of its ring interface, and compares it with the real-time performance of the token ring.
