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.
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]
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: "This feature is useful when the capture is generated on a machine which does not have much storage (e.g. embedded system).
Since the Transmission Control Protocol (TCP) does not perform congestion control on control packets (pure ACKs, SYN, FIN segments), control packets are usually not marked as ECN-capable. A 2009 proposal [7] suggests marking SYN-ACK packets as ECN-capable. This improvement, known as ECN+, has been shown to provide dramatic improvements to ...
