I use TC under Linux to manage traffic on my network. It seems to work
great as you can restrict traffic pretty well. I limit by IP and
distribute the bandwidth to the people that need it most by department.

There is a sample script on my site as well if you want to see an quick
down and dirty example.

Here is the link...

Word of advice if you use a Linux router and TC is to read the man pages
and as much as you can find on the Internet as there are many ways to
set this up.

I recently inherited an environment that allows
streaming to virtually anywhere, and it is definitely
impacting our bandwidth.  I could really use some
advice on what to block, and what not to block.  I
know that there are some legitimate streaming sources
out there (microsoft, webX, etc), but I would like the
ability to deny most of the video/audio streaming
traffic generated by end users.  Thus far, I've only
been able to come up with these 3 UDP protocols to
block:

1558 UDP StreamWorks
7000 UDP VDOLive
7070 UDP RealAudio

It seems like everyone does automatic shifting to port
80 or 8080, though, so is there anything further I can
do on my firewalls to help minimize streaming?

Thanks in advance,
Dave


I agree with Robert, the Packeteer Packetshaper is very good a
controlling 
the streaming traffic.  I use it at work for this purpose and to
control 
other application traffic as well.  Good luck.
