Abstract: A method of managing traffic flows in a network without human intervention which comprises detecting the establishment of at least one of a session and a traffic flow between endpoints, assigning a classification to at least one of the session and the traffic flow, and configuring a number of network devices to provide a certain level of service associated with the classification. Another aspect of the disclosure relates to a service quality management system for a network which comprises a service client structured to detect at least one of a session and a traffic flow established on the network and to produce a classification request for the at least one of the session and the traffic flow, and a service quality manager structured to configure one or more network devices to provide a certain level of service associated with the classification request.

Abstract: Systems and methods for provisioning a virtual circuit having a predetermined Quality of Service (QoS) in packet networks such as the Internet. A system for provisioning a virtual circuit having a predetermined QoS is provided for a packet network, consisting of (1) a circuit client (108) connected to the network and able to generate a request for a packet flow between two nodes at a predetermined QoS; and (2) a circuit manager (CM) able to receive the circuit client's (108) request and process such request in order to provide a route between the two nodes, such route having the predetermined QoS.

Abstract: An automatically passivated n-p junction is formed from a p-type body containing Group II and Group VI elements, one of which is mercury. A passivation layer is then formed having at least one window provided therein on a surface of the p-type body. The p-type body is then subjected to a reactive ion etching process using the passivation layer as a mask to form the n-p junction. Ohmic contacts are then formed on the n-type and p-type regions. The method may be extended to form an array of n-p junctions on a semiconductor body having a plurality of p-type material layers.

Abstract: The present invention allows routers in a digital communications network, such as the Internet, to be given the time awareness that is necessary for timely transfer of real time signals in the form of digital data packets. Timing information generated at the source of the signal is included in the packets in the form of first and second time stamps, which are used by network routers to establish dispatch deadlines by which the packets must be forwarded to ensure time-faithful reconstruction of the real time signal at the destination. The same timing information can be used at the destination to synchronize the clock for presentation of the real time signal to the source clock. The first and second time stamps (a differential time and a dispatch time) are derived by a transmitter unit (100) from a counter (118) that counts pulses from an oscillator (116) that most advantageously is locked to an integer multiple or a fraction of a universally available time measure.
