It appears to improve bandwidth calculation to allow for better transfer of large files.



In order to improve the accuracy of the bandwidth calculation TCP can use Timestamps attached to packages. I have used telnet on the med500 and found that it also has timestamps enabled. You do this using the following command:-

cat /proc/sys/net/ipv4/tcp_timestamps, and get the return 1.

So i have enabled timstamps on my PC using the following command:-

netsh int tcp set global timestamps=enabled

This seems to keep the bandwidth more stable. It may seem counter intuitive to improve thoughput by adding administrative overhead but it appears to work.

TCP timestamps will not improve or change anything related to the performance of TCP sessions. TCP timestamp is used for applications and/or network monitoring tool to capture round trip time...latency. This option puts 10B (I think) in the TCP header set by the host.

The real question should be "Why didn't they make this change on my machine without me knowing?".

It's obviously an attempt to out you as a 'l33t hack3r', since you know how to get to a command prompt.
Hide you dag!
