Network analysis tools study the network in and out, checks for any blockers and if there are, then analyze it and give the results. These tools are important in the world of communication as it is not easy to analyze the network by self. The tools project all the working paths of the networks connected to the system. The tools monitor the performance and the traffic of the networks and the IP addresses. Most of the tools will be similar to the monitoring tools. There are many paid and free tools for analysis of the network.
Network analysis tools are important to anyone who works with the system and communication. Imagine that while using the system, if there are network issues, it can be irritating. And if there are no tools that are analyzing the network, it could take time to dig out the reason for the network issue.
Here are some popular network analysis tools:
- Wireshark
- tcpdump
