WHAT DOES window size mean in Wireshark?

Basically, the window size indicates the size of the receive buffer. Typically the TCP connection will start with a small window size and every time when there is a successful acknowledgement, the window size will increase.

WHAT DOES window size indicate?

The TCP receive window size is the amount of receive data (in bytes) that can be buffered during a connection. The sending host can send only that amount of data before it must wait for an acknowledgment and window update from the receiving host.

What is TCP window size in Wireshark?

The tcp.window_size_value is the raw window size value as read directly from the TCP header, whereas tcp.window_size is the calculated window size, which is based on whether window scaling is applicable or not.

What is window size scaling factor in Wireshark?

If Wireshark sees the three-way handshake, and window scaling is used, Wireshark will know what window scaling factor is used by each side. Wireshark will then calculate the true window size for you by multiplying the value in the window size field by the appropriate multiplier.

What is window size in iPerf?

The default window size that iPerf uses varies by machine type and operating system. If it’s 64 KBytes, with a modest latency of 10 ms, the maximum bandwidth you can get is 52.43 Mbits/sec. For 500 ms the maximum is 524 Kbits/sec.

What is the difference between MTU and window size?

The Internet de facto standard mtu is 576 bytes, but ISPs often suggest using 1500 bytes. Maximum window size is 65,535 bytes.
