If you can define the characteristics of the different bandwidth
streams in terms of ACLs, then there are a number of Cisco
products that could be used. Generally speaking, you would be
creating a route map upon the ACL, and engaging Policy Based Routing
with Traffic Policing. But Traffic Policing -drops- packets if
you go over the limit (and for TCP expects the remote end to notice
the drop and throttle down the window size). If what you want
is to instead buffer the packets and fit them in as bandwidth
permits, with first priority going to the most important streams,
then you want Traffic Shaping, which not as many Cisco devices
support.
If you cannot define the characteristics in terms of an ACL,
such as if your users are doing P2P sharing via port 80, then
you should probably look at a Packeteer (non-Cisco) device.
