In today's world, people's computers are interconnected and interconnected. Small to your Home area network (LAN), the largest one is what we call the Internet. When you manage a networked computer, you are managing one of the most critical components. Because most of the developed applications are network-based, the network connects these key points.That's why we need network monitoring tools. NTOP is one of the best network monitoring tools.

For comprehensive communication intelligence, it can also think of the device flow profiling software, which can be used in different order or users to check the use of data, in different time to check the data, and related to multiple origins of the communication data, such as NetFlow and Ipfix. Looking to the future, some of the leaders in it should focus on new skills in order to put them into arsenals. For example, IP
