    Monitoring network users’ using packet Analysis
    (2012) Kyeremateng, Kwabena
    This study was conducted to come out with a tool that aid in monitoring network users that traverses outside their domains during peak working hours in a network environment using packet analysis. The main aim of this study was to design non-router based application to monitor users’ in a LAN or WAN. As an enhancement to the previous ones, the tool combined passive and active monitoring and analyzes the packets communication based on source and destination IP address. Find out the effects of this traversal and what these network traversal brings characterized by time, packet size, delay, hop count and bandwidth consumption. In this work, communication of analyzed results to network users and their support was made possible as an internal helpdesk was included in the design as well as network interface card verifier was also included as an enhancement. The captured packet from live network under surveillance obtained using the applications were presented in a tabular and graphical form. The results of the table and graph were then used as the basis for the analysis. The results showed that network users can be visually monitored using IP address and they can be made to give account of network usage outside their domain; users’ activities outside their normal work schedule on the internet leads to additional traffic. This was seen in the graph as packet size, hop count, TCP window size and transmission delay affected network performance.
