The window size of a TCP connection
This command sets the size of the TCP window to
bytes. Changing the size of the TCP window modifies the size and number of packets that can fit within that window. With the default window of 2,144 bytes, you could buffer two 1,000-byte packets, or 21 100-byte packets. Regardless of the window’s size, the number of packets within the window is restricted to the values set by the
ip tcp queuemax command; they default to 5 for TTY interfaces (async and console interfaces) and 20 for other interfaces. The maximum size of the window is 65,536 bytes.
