TCP报文通常有3部分组成：IP Header + TCP Header + Payload 但是，当前主流操作系统的TCP/IP协议栈，...
Window Size是TCP流量控制的重要机制之一。通过调整Window Size，接收方可以通知发送方当前能够处理的数据量...
This is because the field in theTCP header is only 16-bits wide. TCP's receive window size is particularly important in satellitecommunications, because the maximum throughput of a single TCP connection is bounded bythe following equation:Without large windows, the maximum effective throughput for ...
The default can start at 17520 for Ethernet, but may shrink slightly when the connection is established to another computer that supports extended TCP header options, such as Selective Acknowledgements (SACK) and TCP Timestamps, because these options increase the size of the TCP header beyond the...
value exceeding14, the TCP should log the error but use14instead of the specified value. The scale factor applies only to the Window fieldastransmittedinthe TCP header; each TCPusingextended windows will maintain the window values locallyas32-bit numbers. For example, the"congestion window"comput...
The window size is still limited to 216or 65536 bytes,however, a new scaling factor option has been added to allow TCP to fully utilize higherbandwidths over satellite links. This new option is used to multiply the window size value foundin the TCP header window field to obtain the true ...
TCP Sliding Window The working of the TCP sliding window mechanism can be explained as below. The sending device can send all packets within theTCP window size(as specified in theTCP header) without receiving anACK, and should start a timeout timer for each of them. ...
Um die Größe des Empfangsfensters anzugeben, enthält der TCP-Header ein 16-Bit-Fensterfeld. Wenn der Empfänger Daten erhält, sendet er ACKs zurück zum Sender und gibt darin die erfolgreich empfangenen Byte an. In jeder ACK gibt das Fensterfeld die Anzahl der Byte wieder, die...
TCP Receive Window In the above diagram, the client and server are advertising their window size values as they communicate. Each TCP header will display the most recent window value, which can grow or shrink as the connection progresses. In this example, the client has a TCP receive window ...
The default window size can start at 17520 for Ethernet, but may shrink slightly when a connection to another computer is established that supports extended TCP options (such as SACK and TIMESTAMPS) because these options increase the TCP header beyond the usual 20 bytes, which decreases room fo...
