I am looking for some bandwidth management software with these
following specifications:

1)	Does not need to run on any specific hard ware i.e. standard PC
hardware.

2)	Preferably runs on Windows 2000 or XP and does not need the server
flavour to run correctly.

3)	Has the ability to manage the bandwidth of every workstation on the
network controlling both uploads and downloads from those
workstations separately . In other words the system manager would be
able to state
the amount of upload bandwidth and download each specific PC is
allowed to use at any one time by MAC address or by groups of PCs and
throttle the
bandwidth if the PC uses too much.

4)	Is able to throttle or block specific traffic from specific
applications (p2p, etc.) specifying how much bandwidth they are able
to use for uploads and downloads. E.g. the software should be able to
throttle the bandwidth of a Kazaa application specifying the amount of
download bandwidth it can use and the amount of upload bandwidth it
can use separately.

5)	The software should only run on one main server that sits on the
network at the point of exit to the Internet.  No other software
running on workstations should be needed.

6)	If the software would be able to intelligently calculate the
bandwidth available going out to the Internet and so share the
bandwidth fairly to all PCs on the network when they need it. E.g. a
person on the network is using a p2p download
program and there is only a 1 mb ADSL connection out to the internet.
If this person is downloading and uploading loads of stuff the
Internet will slow down dramatically for all other users. What the
software needs to be able to do is dynamically throttle the bandwidth
of this person when others need the Internet slowing the downloads for
him dramatically and not affecting the other people visibly.

7)	The software should preferably NOT cost more than $800 for a
licence to manage 60 workstations.

Thanks for your help.
