【摘要】：本文以大庆市龙凤区政府信息网络管理为背景，重点研究了在日常网络管理维护中如何实现网络的配置，以及如保实现网络数据包的捕获、分析和管理的工作，以提高政府网络管理的效率。本文主要完成了以下几个工作：从网络实现原理、CSMA/CD技术、网络OSI模型、TCP/IP协议等内容知识对网络进行了简单介绍，以及对相应数据报头字段格式进行了说明。介绍了不同协议所处的不同层次以及各层协议之间是如何进行数据交换等原理性的知识。其次，针对目前主流的网络数据捕获技术进行了介绍和对比，并重点介绍本文所使用的基于.NET框架下的SharpPcap架构，以及SharpPcap架构的发展过程及应用技术等内容。再次，，为了保证能够顺利的进行网络数据采集工作，需要对网络设备进行配置管理。本文主要以华为设备配置管理为例，介绍了端口镜像、远程交换端口分析（RSPAN）源交换机、中间交换机和目的交换机之间通信的原理以及实现的过程，并根据实际工作情况，对交换机进行了配置。在数据包捕获及分析过程中，本文首先根据协议的不同对链路层、网络层和传输层的各个数据包进行分别捕获，根据协议原理分析了它们的构造细节，以及相应的字段内容。然后，根据不同协议提供的不同内容进行相应的统计和分析，再将结果以图形化的形式直观的展示出来，以方便用户使用。上述的研究成果，在大庆市龙凤区政府网络管理工作中，得到了应用与验证，证明以上的所提出的基于协议分析的网络管理技术是可行的、实用的，满足了龙凤区政府网络管理的需求。
[Abstract]:Based on the background of government information network management in Longfeng District of Daqing City, this paper focuses on how to realize network configuration in daily network management and maintenance, and how to capture, analyze and manage network data packets. To improve the efficiency of government network management. The main work of this paper is as follows: a brief introduction is made to the network from the network realization principle, the network OSI model and the TCP / IP protocol, and the format of the corresponding header field is explained. This paper introduces the different levels of different protocols and how to exchange data among them. Secondly, this paper introduces and compares the current mainstream network data capture technology, and focuses on introducing the SharpPcap architecture based on .NET framework, the development process and application technology of SharpPcap architecture and so on. Third, in order to ensure the smooth network data collection, network devices need to be configured and managed. Taking Huawei equipment configuration management as an example, this paper introduces the principle and realization process of communication between port mirror, remote exchange port analysis of RSPAN) source switch, intermediate switch and destination switch. The switch is configured. In the process of packet capture and analysis, we firstly capture each packet of link layer, network layer and transport layer according to the different protocols, and analyze their construction details and corresponding field contents according to the principle of the protocol. Then, according to the different contents provided by different protocols, the corresponding statistics and analysis are carried out, and then the results are displayed graphically and intuitively, so as to facilitate the users to use them. The above research results have been applied and verified in the government network management of Longfeng District of Daqing City, which proves that the proposed network management technology based on protocol analysis is feasible and practical. Meet the needs of the government network management.
