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.
A non-routing node in promiscuous mode can generally only monitor traffic to and from other nodes within the same collision domain (for Ethernet and IEEE 802.11) or ring (for Token Ring). Computers attached to the same Ethernet hub satisfy this requirement, which is why network switches are used to combat malicious use of promiscuous mode.
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.
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.
Windows versions since Windows Server 2008 and Windows Vista support ECN for TCP. [11] Since Windows Server 2012, it is enabled by default in Windows Server versions, because Data Center Transmission Control Protocol (DCTCP) is used. [12] In previous Windows versions and non-server versions it is disabled by default.
In the field of computer network administration, pcap is an application programming interface (API) for capturing network traffic.While the name is an abbreviation of packet capture, that is not the API's proper name.

tcpdump is a data-network packet analyzer computer program that runs under a command line interface.It allows the user to display TCP/IP and other packets being transmitted or received over a network to which the computer is attached. [3]
