摘　　要：以陕西煤矿瓦斯监测远程联网为背景,研究其联网网络的QoS保障策略实现。由于现有的各种QoS实现机制无法单独为陕西煤矿瓦斯监测联网网络的QoS提供保障,因此在实际应用中必须结合多种机制才能得到较好的QoS保障效果。比较了传统IP网络的QoS结构体系,通过分析IntServ和DiffServ两种模型的基本原理、工作方式,并指出其各自的优缺点和网络应用环境,设计了将RSVP协议与DiffServ模型相结合来满足瓦斯监测数据传输实时性的要求;针对陕西煤矿瓦斯联网的特性,提出了将TCP拥塞控制算法与IP层拥塞控制算法相结合的算法模型,并且该模型的应用可以在原有单一拥塞控制的基础上有效地提升跨地区网络的QoS特性。This paper makes the gas remote monitor network as background to do some research on the QoS guarantee of the network. QoS is a synthesis guide line which can be used to estimate the degree to satisfy with some server, which is a technology to solve the problem of delay and congestion in network. It must integrate multi - QoS mechanism to get good QoS guarantee in the practical application. Three QoS models in the IP net application and homologized affective factors are demonstrated. Meanwhile,the field of QoS protection strategy arrangement in Shaanxi coal mine gas network has been picked up as the example. For this situation,the comparison to the different QoS models is doing strictly. By combining the TCP congestion control arithmetic with IP congestion control arithmetic, the paper also emphatically describes the corresponded arithmetic model for that. Stimulatingly, it is promoted the QoS characteristic over- area effectively, which it is based on the original single congestion control.
