I want to transfer a large amount of data between Sydney and Perth (opposite sides of Australia), using Windows Explorer, and network drives, in a Windows Server terminal services session.

I don't want to negatively impact the bandwidth available to other users.

I can wait until close of business, but I'd like to see if there was a way I could initiate a transfer, but throttle the file transfer network speed.

Is this possible?

How do you plan to transfer the files? FTP? What does COB stand for (sorry I don't get all of these abbreviations right off the bat)? –  Caleb Xu Jan 10 at 2:14
    
Thanks. Added detail. Windows Explorer, and close of business. –  Steve Jan 10 at 2:31
    
Does this have to be windows explorer? Cyberduck would let you set the speed of the transfer –  Journeyman Geek Jan 10 at 4:18
    
It is a Windows network share that I am copying from. I'm not sure if the Windows server accepts FTP connections. –  Steve Jan 10 at 8:13

Its probably easiest to wait till close of business. In order to do this using Windows Explorer you will need to limit your underlying connection between the 2 systems which is not trivial - generally this is done at the router level (as it is not part of Windows Explorer - unlike, for example some SCP clients which have this functionality built in).

You havn't mentioned the speeds of the points, but if they are both faster then 10 megabit, and if you can find out how to do it (old hardware, playing with the negotiation speeds of one of the network card on your machine), a hack might be to force your NIC to 10 megabit which will limit this.

Stepping back though - I'd imagine the latency between Perth and Sydney is not inconsequential. You may find that, providing you move stuff 1 file at a time, the performance of your network might slow a bit but be quite tolerable due to the "stepping down" of the performance of the transfer due to the distances/latency involved. As ironic as it sounds, even better if there is a bit of packet loss between the sites [For TCP connections - which these are - Packet loss acts as a signal to slow down the transfer ]

It would have been better to use some transfer software or a personal bittorrent network but you could try using some software to do it for you. Here is one even though I have not tried using it personally http://www.netlimiter.com/
