If in case of, the acknowledgement not received by the server or any congestion occurs in the network or in case of any lost in sent packets that will cause the TCP retransmi. TCP retransmissions happen when there is packet loss or congestion, which causes high latency and low speed. Nur wir kann ein normaler Anwender oder auch jemand im Support solche Daten ermitteln Im Idealfall könnte er mit Wireshark u.a. Verlorene Pakete, und dazu zählen lange Laufzeiten ebenso, sind immer unerwünscht und ein Zeichen einer schlechten Leitung. Because the corresponding port on the server is not open, it responds to the request with rst, and the rst responds to the initial sequence number. Answer (1 of 3): The packets sent by the server using TCP, received by the client and it has to give the acknowledgement. Jede Nutzung von Diensten über TCP/IP ist abhängig von der Zuverlässigkeit der Verbindung. The reason is that the sender resends a message segment that has received a response.īack to this packet capture, the client initiates a connection request to the server. This is an additional prompt given by Wireshark to help users better understand the message process. Recently, I found an expert tip “TCP spurious retransmission” that I haven’t seen (or paid attention to) before, as shown in the following figure: TCP SYN retransmission can happen if you want to connect to a remote host and the port on the remote host isn’t open (see example below). Three TCP segments were fast retransmitted following the fast retransmission algorithm in RFC 2581. This article is related to Wireshark application, and does not involve the implementation of kernel protocol stack. Meaning, for 54 TCP segments the corresponding ACK was not received within the timeout.
