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. ECN support can be enabled using a shell command such as netsh interface tcp set global ecncapability=enabled.
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.
Delayed ACKs can give the application the opportunity to update the TCP receive window and also possibly to send an immediate response along with the ACK. For certain protocols such as Telnet , delayed ACKs can reduce the number of responses sent by the server by a factor of 3, by combining the ACK, window update and the response data into one ...
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 ...

The persist timer is used to protect TCP from a deadlock situation that could arise if a subsequent window size update from the receiver is lost, and the sender cannot send more data until receiving a new window size update from the receiver. When the persist timer expires, the TCP sender attempts recovery by sending a small packet so that the ...
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] Distributed under the BSD license, [4] tcpdump is free software.
The command reports the round-trip times of the packets received from each successive host (remote node) along the route to a destination. The sum of the mean times in each hop is a measure of the total time spent to establish the connection. The command aborts if all (usually three) sent packets are lost more than twice.
