Abstract: The present invention relates to a garlic planting device for planting garlic cloves while maintaining an upright state thereof at the time of planting the garlic cloves. The garlic planting device of the present invention comprises at least one guiding hopper for guiding a garlic clove with a root portion thereof directed in a downward direction, and a planting means for planting the garlic clove supplied from each of the guiding hoppers.

Abstract: An asynchronous transfer mode (ATM) protection triggering method using “received-AIS” flag determines whether the failure generation position is generated within a protected domain or not, by determining whether the “received-AIS” flag is “0” in case that a node detecting a failure link transmits an end-to-end AIS cell to a downstream side node, and a source point passing the end-to-end AIS cell sets the “received-AIS” flag to “1” and then receives “AIS cell receiving” signal from a sink point of the protected domain, thereby obviating a CRC-10 calculation problem and a backward compatibility.

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.

Abstract: The present invention relates to a method for controlling the peak cell rate spacing of multiplexed ATM traffic.

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.
