Design and Development of Network Protocol Analyzer Based on SharpPcap
Abstract: This paper mainly discusses the development and implementation of a network protocol analyzer for SharpPcap based on, mainly from the needs analysis, feasibility analysis, overall structure design, detailed design to investigate and analyze the development of network protocol analyzer and realization method base on SharpPcap. The network protocol analyzer using Dot Net technology, mainly use SharpPcap library access to the network status of the current system and the network packet capture and filtering, and use PacketDotNet library to capture network packets and get separation layer by layer, from the bottom to the top of the letter to the network packets for analysis, to a certain format display and save the results. The protocol analyzer to network management personnel to provide reliable first hand information about the state of the network, can help network management personnel to quickly and accurately locate network faults, discovers the existence the faulty nodes from the network and rapid troubleshooting.
