Wireshark is a free and open-source packet analyzer.It is used for network troubleshooting, analysis, software and communications protocol development, and education. . Originally named Ethereal, the project was renamed Wireshark in May 2006 due to tradema
Essential DPI functionality includes analysis of packet headers and protocol fields. For example, Wireshark offers essential DPI functionality through its numerous dissectors that display field names and content and, in some cases, offer interpretation of field values.
Packet capture is the process of intercepting and logging traffic. As data streams flow across the network, the analyzer captures each packet and, if needed, decodes the packet's raw data, showing the values of various fields in the packet, and analyzes its content according to the appropriate RFC or other specifications.
The following tables compare general and technical information for several packet analyzer software utilities, also known as network analyzers or packet sniffers. Please see the individual products' articles for further information.

The first known use of the term PCAP-over-IP is by Packet Forensics in 2011. [2] However, the concept behind PCAP-over-IP was mentioned already in 2008 as part of a feature request for Wireshark. [3] The need for this feature was motivated as follows:
[1] [2] [3] It accepts as input files produced by packet-capture programs, including tcpdump, Wireshark, and snoop. tcptrace can produce several different types of output containing information on each connection seen, such as elapsed time, bytes and segments sent and received, retransmissions, round trip times, window advertisements, and ...
Packet Decoding is the capture and analysis of the network traffic generated during Packet Play. In order to determine the targeted network's response to the scenario created by Packet Play, the response must be captured by a packet analyzer and decoded according to the appropriate specifications.
