  2. 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]

  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. Wireshark - Wikipedia

    en.wikipedia.org/wiki/Wireshark

    Wireshark is very similar to tcpdump, but has a graphical front-end and integrated sorting and filtering options.. Wireshark lets the user put network interface controllers into promiscuous mode (if supported by the network interface controller), so they can see all the traffic visible on that interface including unicast traffic not sent to that network interface controller's MAC address.

  5. 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.

  6. Network packet - Wikipedia

    en.wikipedia.org/wiki/Network_packet

    At the transmitter, the calculation is performed before the packet is sent. When received at the destination, the checksum is recalculated, and compared with the one in the packet. If discrepancies are found, the packet may be corrected or discarded. Any packet loss due to these discards is dealt with by the network protocol.

  7. 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 ...

  8. Deep packet inspection - Wikipedia

    en.wikipedia.org/wiki/Deep_packet_inspection

    The secure room contained Narus traffic analyzers and logic servers; Narus states that such devices are capable of real-time data collection (recording data for consideration) and capture at 10 gigabits per second. Certain traffic was selected and sent over a dedicated line to a "central location" for analysis.

  9. Protocol analyzer - Wikipedia

    en.wikipedia.org/wiki/Protocol_analyzer

    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).
