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.
Protocol analyzers vary in their abilities to display and analyze data. Some protocol analyzers can also generate traffic. These can act as protocol testers. Such testers generate protocol-correct traffic for functional testing, and may also have the ability to deliberately introduce errors to test the device under test's ability to handle errors.
Wireshark is a data capturing program that "understands" the structure (encapsulation) of different networking protocols. It can parse and display the fields, along with their meanings as specified by different networking protocols. Wireshark uses pcap to capture packets, so it can only capture packets on the types of networks that pcap supports.
The software features algorithms designed to predict future network statistics. Auto discovery The software automatically discovers hosts or network devices it is connected to. Agentless The product does not rely on a software agent that must run on hosts it is monitoring, so that data can be pushed back to a central server. "Supported" means ...
The Xplico's software architecture provides: an input module to handle data input (from probes or packet sniffer) an output module to organize the decoded data and presenting them to the end user; and; a set of decoding modules, called protocol dissector for the decoding of the individual network protocol.
[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 ...
A protocol analyzer is a tool (hardware or software) used to capture and analyze signals and data traffic over a communication channel.Such a channel varies from a local computer bus to a satellite link, that provides a means of communication using a standard communication protocol (networked or point-to-point).
A packet-switched network transmits data that is divided into units called packets.A packet comprises a header (which describes the packet) and a payload (the data). The Internet is a packet-switched network, and most of the protocols in this list are designed for its protocol stack, the IP protocol suite.
