Abstract

Abstract: In order to make sure of the QoS（Quality of Service） for the integrated service，such as voice video data，and so on，in the computer networks，it is necessary to solve the problems of priority control.So，under the condition that giving top priority to sending frames with the highest priority and ensuring the sending of lower priority frames（especially the lowest priority frames），“The Improved Polling Model” is first introduced.So that，it expands the use of the polling access model in the integrated service Bus LAN.Simulation results show that the improved protocol increases the QoS for the integrated service Bus LAN.

Key words: polling, priority, integrated service, transmitting polling

摘要： 为了保证话音、视频、数据等综合业务在计算机网络通信中的服务质量QOS，需要解决优先级控制问题。为此，在保证高优先级帧尽可能优先发送，同时适当兼顾低优先级，特别是最低优先级帧发送的前提下，首次提出了“改进型轮询方式”，从而扩展了轮询介质访问方式在综合业务总线LAN中的应用。模拟实验表明，改进后的协议提高了综合业务总线LAN的QOS。
