  • Patent number: 5872771
    Abstract: Disclosed is an adaptive connection admission control method by traffic measurement and estimation, which includes the steps of determining whether a connection is to be accepted or not by using the peak cell rate among the user-declared traffic parameters and the estimation value of the average cell rate of individual connections under service as inputs when a connection set-up request signal is inputted into the system, the step of reducing the number of connections when a connection release request signal is inputted, and the step of calculating the measured value of the average cell rate of all the connections passing through an output link and the estimated value of the average cell rate of individual connections when the measuring interval has ended, to thereby accomplish accurate and smooth connection controls.

  • Patent number: 5802040
    Abstract: A congestion control unit and method in an ATM network is disclosed. The congestion control unit includes a congestion detector, a congestion controller and a routing controller. The congestion detector receives the measured number of cells generated from an output link through an ATM switch module, transmits the measured number of cells to an adaptive connection admission control unit, and detects the state of the output link by use of a utilization of a cell transmission link. The congestion controller receives congestion state information from the congestion detector and receives a cell loss ratio through the ATM switch module. The congestion controller transmits a backward resource management cell to a user or generates a routing control request signal so as to assign the load of the input traffic to another affordable link, and supplies a monitor parameter to the ATM switch module.

  • Patent number: 5224375
    Abstract: An improved apparatus for automatically measuring the viscosity of a sample liquid is disclosed. The apparatus comprises a plurality of viscosimeter tubes mounted in a constant temperature bath, a plurality of vessels adapted for containing the sample liquid, a valve system for controlling the injection and the removal of the sample liquid into and from the viscosimeter tubes and the ascent and descent of the sample liquid in the viscosimeter tubes, a driving circuitry for the valve system, a photosensing device for sensing the meniscus of the liquid at predetermined indication marks of the viscosimeter tubes and a system of measuring the flow time of the sample liquid between two predetermined marks and computing the viscosity of the liquid based on the measured flow time.
