The Research On Qos Guarantee Strategic Realization Of Shannxi Coalmine Gas Monitor System Network

The monitor platform of Shannxi coalmine gas network take aim at the gas disaster which has a serious status in the coalmine at present, and adopt standard and general communication manner to construct transfer system,and transplant the industry network of coal corporation to the IP network platform which form information-based network data source and improve the degree of data utilization and data share at the base of that. How to resolve the demand of IP network QoS and ensure the industry information such as gas monitor to transfer neatly in the network according to business characteristics, which is the problem that will be discussed and resolved.This paper is imbursed by the nation 863 project item《A gas remote monitoring system of digitalization in coal mine》(project No. 2005AA133070), which makes the gas remote monitor network be a background to do some research on the QoS guarantee of the network. QoS is a synthesis guide line that 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. We must integrate multi-QoS mechanism to get good QoS guarantee in the practical application. This paper demonstrated three QoS models in the IP net application and homologized affective factors. Meanwhile, the field of QoS protection strategy arrangement in Shannxi coalmine gas network is 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. To accomplish the deployment of network QoS guarantee strategy after analyse and rebuild the whole network QoS, which is based on the topology frame of gas monitor system network.Finally, the imitation and simulation of gas monitoring network QoS guarantee strategy model has been taken. There are indication that the result could be satisfied with the goal of the project design, which also promotes the QoS characteristic of Shannxi Coalmine gas monitor system network.
