Computer Network is a growing field every day. Networking has made life easy. Computer networks always have a big risk of security problems. However, to better understand real problems in a network and to solve them, it’s important to go to the packet level. It is believed that all network problems arise from the packet level. This is where packet analysis plays a big role in computer networks. Network analysis, protocol analysis or simply sniffing are the other names of packet analysis. The purpose of this research paper is to monitor and analyze the network traffic packets of various protocols like TCP/IP, HTTP, ARP, ICMP etc. using a tool called Wireshark. Wireshark is a free and open - source packet analyzer. To analyze the packets of different protocols we are using different parameters are frame no. frame length, IP source, IP destination, header length of the packets and also window size value etc.
