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.
