摘要
此项研究主要针对大庆油田某作业区的实际网络现状,对该作业区进行网络分析和规划,在该作业区现有的有线网络基础上扩充无线网络,实现有线网与无线网的综合,构成一个完整的油田传输信息体系。同时利用OPNET MODEL-ER仿真平台为该作业区新建混合网络建立仿真模型(网络模型、节点模型和进程模型),分析相关模型中主要模块的作用和工作机理,对已建立的网络模型进行仿真,在不同的参数设置下,通过对比分析时间延迟、丢包率等统计特性,得出数据包分组、数据率和拆分门限对网络性能的影响,最终决定改进网络的最佳组网方案。
The study aims at the actual network status of one work section in Daqing oil field, makes a network analysis and planning for the new mixed model of this work section, expends wireless network for the work section on the basis of existing network,and conjoins wire and wireless network together to form an integrated oil field information transfer system. At the same time,using OPNET MODELER simulation flat roof to structure simulation models （network models,node models and a process model）, and analyzing the functions and work mechanism of the major modules for related models,making a simulation for the structured network models, then according to the different parameters, analyzing the individual statistics comparatively such as delay, data dropped and so on, the effects of data packet, data rate and fragmentation threshold to the network performance are gained. After all these, the best structure network scheme for this improved section is determined.
