Network traffic measurement and analysis

Today one cannot think of life without the Internet. The Internet has grown at a very fast pace, which has resulted in heavy Internet traffic. Most of today's internet traffic is due to video streaming services such as YouTube and Netflix. The Average traffic load has risen, and data traffic patterns have also become unpredictable. Therefore, network traffic monitoring and analysis have become essential in order to troubleshoot and resolve problems effectively when they occur, so that network services do not stand still for long durations of time. Traffic monitoring is a technique which constantly monitors the network traffic and notifies the administrator whenever there is an outage. There are many network monitoring tools available for network administrators, which use different monitoring techniques in order to monitor and analyze network traffic. In this paper, we present different network monitoring approaches and different tools that monitor and analyze network traffic. In addition to this, we also present results by comparing different network monitoring tools.
