SoftPerfect Bandwidth Manager

SoftPerfect Bandwidth Manager monitors your LAN traffic and
limits bandwidth according to the rules specified. These rules are created with
IP and MAC addresses, protocols, ports (for TCP/IP) and network interfaces. It
also has a Quota Manager, which can be configured to permit users to upload or
download a specified data amount within the specified period at one speed but
decrease their speed or block them once they exceed the limit. It doesn't
require anything to be installed on the client system, rather it provides
centralized configuration from a single network location. 

Another interesting thing it has is a Timetable Manager. That is, it lets you create
rules that get activated on a particular time of a day. The software costs USD
99 for a single-user

license, and works on Win XP/2000/2003. On startup, it asks you to login to a
host. By default the Host is 'localhost' and the password is left blank.
