We [COLT Internet] are using the packeteer PS-4000 and it does 
everything that the spec says we filled up a 100M ethernet with
several streams of data and it worked very well.


> I was wondering if anybody out there has had any experience with "Packet

> window size information to slow traffic down if needed.
> The one we have been looking at is called "The Packeteer"

> really good picture of a pig in the ad).
> Do these things work as advertised?  Is anybody actively using them inside

> snake-oil...
> Thanks for any information.  Email if you like, I will post a summary if
