Packet Sniffing and Network Traffic Analysis Using TCP—A New Approach

Due to the rapid development of Internet the size of computer network are continue to grow in size. Thus the network traffic are increasing drastically. To keep the data transfer smooth and faster in the network the monitoring, and management of network traffic is an important factor in field of computer network. The data, information are communicated via TCP or UDP Internet protocol between nodes in the network. These transport layer protocol carry the packet or datagram from source-to-destination site. The packet analysis or packet sniffing is process of capturing the packet and analyze the log traffic passes over the network or a part of network. Packet sniffer is used for wired or wireless network. A tool is developed to accomplish the monitoring task that removes deficiency of existing tool. The packet sniffer is used to capture the traffic and analyzed those captured traffic. The report is generated based on analyzed captured traffic. Various transport layer protocol like TCP, UDP, etc., can be implemented for analysis and filtering can be done based on protocol used. A new approach of packet sniffing and network traffic analysis over TCP connection oriented network using Wireshark software has been discussed in this paper.
