  2. Wireshark - Wikipedia

    en.wikipedia.org/wiki/Wireshark

    Wireshark uses pcap to capture packets, so it can only capture packets on the types of networks that pcap supports. Data can be captured "from the wire" from a live network connection or read from a file of already-captured packets. Live data can be read from different types of networks, including Ethernet, IEEE 802.11, PPP, and loopback.

  3. PCAP-over-IP - Wikipedia

    en.wikipedia.org/wiki/PCAP-over-IP

    PCAP-over-IP is a method for transmitting captured network traffic through a TCP connection. [1] The captured network traffic is transferred over TCP as a PCAP file in order to preserve relevant metadata about the packets, such as timestamps.

  4. pcap - Wikipedia

    en.wikipedia.org/wiki/Pcap

    A capture file saved in the format that libpcap, WinPcap, and Npcap use can be read by applications that understand that format, such as tcpdump, Wireshark, CA NetMaster, or Microsoft Network Monitor 3.x. The file format is described by Internet-Draft draft-ietf-opsawg-pcap; [5] the current editors' version of the draft is also available. [6]

  5. Tcptrace - Wikipedia

    en.wikipedia.org/wiki/Tcptrace

    [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 ...

  6. Packet analyzer - Wikipedia

    en.wikipedia.org/wiki/Packet_analyzer

    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.

  7. tcpdump - Wikipedia

    en.wikipedia.org/wiki/Tcpdump

    tcpdump prints the contents of network packets. It can read packets from a network interface card or from a previously created saved packet file. tcpdump can write packets to standard output or a file. It is also possible to use tcpdump for the specific purpose of intercepting and displaying the communications of another user or computer.

    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.

  9. Ethernet flow control - Wikipedia

    en.wikipedia.org/wiki/Ethernet_flow_control

    Wireshark screenshot of an Ethernet pause frame. Ethernet flow control is a mechanism for temporarily stopping the transmission of data on Ethernet family computer networks. The goal of this mechanism is to avoid packet loss in the presence of network congestion. The first flow control mechanism, the pause frame, was defined by the IEEE 802.3x ...
