An administrator who needs to view packets and decode and analyze their contents should use a packet analyzer or network analyzer application. Packet analyzers, also known as protocol analyzers, are tools that are used to capture, decode, and analyze network traffic.
Network administrators and other IT experts frequently utilize packet analyzers to diagnose network issues, improve network speed, and find security flaws. They can offer comprehensive details on each packet's contents, including the source and destination addresses, the kind of protocol being used, and the data in the payload.
There are numerous options for packet analyzer software, from straightforward command-line tools to intricate graphical user interface (GUI) programs. Applications for packet analysis such as Wireshark, tcpdump, and Netmon are widely used.
An administrator must set up a packet analyzer application to capture packets from the desired source and destination devices on a network-connected device before using it.
