Research And Practice On Network Management Technology Based On Protocol Analysis

Based on the background of Daqing City Longfeng District government informationnetwork management, this paper focuses on how to realize the network configuration in dailynetwork management and maintenance, as well as the implementation of network packetcapture, data analysis and management, to improve the efficiency of government networkmanagement.This paper mainly has completed the following tasks: firstly gives a brief introduction, about thecontents such as principle of network realization, CSMA/CD technology, network OSI model, TCP/IPprotocol, and so on. And the corresponding data header field format are described. Describes the differentlevels between the different protocols and principle knowledge about protocols of each layer how to carryout data exchange.Secondly, the current mainstream data capture techniques are introduced and compared,and focuses on SharpPcap architecture on the.NET framework using in this article, and thedevelopment process of SharpPcap architecture and the content of application technology.Again, in order to be able to ensure carrying out the network about network dataacquisition smoothly, the network device configuration management is needed. This paper inthe case of Huawei device configuration management,introduces port mirroring, sourceswitch of remote Switched Port Analyzer (RSPAN), the principle of communication betweenintermediate switch and destination switch,And according to the actual working condition,carrying out configuration on the switch.Packet capture and analysis, this paper were captured Depending on the data link layer,network layer and the transport layer of each data packet protocol, according to the protocolprinciples analyzed their construction details, and the corresponding field contents. Then,depending on the different contents of the corresponding protocol provides statistics andanalysis, and then the results in the form of an intuitive graphical display of up to facilitate theusers.In the data packet capture and analysis process, this paper firstly according to thedifferentiation of protocol carries out capturing each packet of link layer, network layer andthe transport layer respectively,according to the principle of protocol analyses the structuredetails as well as the corresponding field content. Then, according to the different contents ofdifferent protocols carrying out corresponding statistics and analysis,then the results aredirectly displayed in graphical form, to facilitate users.The above research results, in Daqing City Longfeng District government networkmanagement, has been applied and verified, proving that the above network managementtechnology based on protocol analysis proposed is feasible and practical, to meet the needs ofLongfeng District government network management.
