RE: Traffic Management

Check Point offers a product called Floodgate that lets you set priority by
% or max kbps. There are several other product vendors that offer similar
products dedicated to traffic shaping/control.  Cisco routers also have a
parameter that lets you limit certain types of traffic to a max bandwidth. 

If you are using a caching proxy you may be able to set a bandwidth limit on
that proxy. The result of all these is that certain categories of traffic
(http vs. ftp vs. e-mail vs. specific ports) get throttled.  The better
solutions can specify bandwidth by protocol and source/destination so your
e-mail server to corporate HQ server can get 50% of the bandwidth while
non-corporate smtp gets 10% and http gets 5% etc.

They all require establishing a corporate policy and then setting up some
rules.

You should look into bandwidth shaping solutions.  One that I have personal 
experience with, used to be called AccessPoint from Xedia.  This company 
was sold to Lucent over a year ago.  These routers use "Class Based 
Queuing" to allocate available bandwidth based on applications as well as 
IP addresses.

Cisco also has "Quality of Service" products but I found AccessPoint to be 
more effective.

Good luck,
