Abstract: A traffic controller is provided which integrates black-box tests of unauthorized applications to extract application characteristics from associated Internet traffic, exploits the networking information learned by host clients, actively scans and controls hosts on the corporate network, and dynamically configures a corporate firewall to block traffic to and from critical application network elements. As a result, the traffic controller effectively manages unauthorized applications and their associated traffic in a corporate environment.

Abstract: A method and apparatus are provided for adjusting the volume of data communicated between a transmitter and a receiver on a network, in a time interval. The method involves producing a desired volume value in response to a volume value specified by the receiver and a difference between a target departure volume and an estimate of arrival volume of data at a queue through which data passes from the transmitter to the receiver, and communicating the desired volume value to the transmitter in response to an acknowledgement signal produced by the receiver.
