Tcp1323Opts Parameter

NOTE:

This parameter is only for Windows Server 2003.

This parameter determines whether TCP uses the time-stamping and window scaling features described in RFC 1323, TCP Extensions for High Performance.

For more efficient use of high bandwidth networks, use a larger TCP window size. The TCP window size field controls the flow of data and is limited to 2 bytes, or a window size of 65,535 bytes.

Since the size field cannot be expanded, a scaling factor is used. The TCP window option increases the maximum window size from 65,535 bytes to

1 gigabyte. The TCP receive window is the amount of data the sending host can send on a connection at one time.

When the value for window size is added to the registry and its size is larger than the default value, Windows attempts to use a scale value that accommodates the new window size.

Tables 7-3and 7-4show the four Tcp1323Opts settings.
