Abstract: An apparatus and method for analyzing bottlenecks in a data distributed processing system. The apparatus includes a learning unit mining and learning bottleneck-feature association rules based on hardware information related to a bottleneck node, job configuration information related to a bottleneck causing job, and/or I/O information regarding a bottleneck causing task. Based on the bottleneck-feature association rules, a bottleneck cause analyzing unit detects a bottleneck node among multiple nodes performing tasks in the data distributed processing system, and analyzes the bottleneck cause.

Abstract: A network relay apparatus and method using a software module that easily support various network protocols and new network protocols. The network relay apparatus includes a first modem unit communicating with a first network using a first protocol, a second modem unit communicating with a second network using a second protocol, a bridge unit converting data to be suitable for the first and second protocols when the data is exchanged between the first modem unit and the second modem unit, and a controller generating the first and second modem units and the bridge unit in a software manner.

Abstract: A control device by which a priority for service is assigned based on quality of service (QoS) for each control point residing on a network and services are provided according to the assigned priority. The control device includes communication S/W module which receives control messages transmitted from the control points or transmits reply messages to the control points, a priority management module which determines the priority for service based on a QoS level for each control point, a UPnP S/W module which analyzes the control messages received from the communication S/W module and controls service operations corresponding to the analyzed control messages, and a service S/W module which performs the service operations under the control of the UPnP S/W module. Consistent with the present invention, the priority for service is assigned according to the QoS for the control point and the services are provided according to the assigned priority.

Abstract: A software-controlled communication method and an apparatus thereof is disclosed. The apparatus includes a radio frequency (RF) front end unit for sending a data signal or a voice signal to a cordless phone base station via an antenna, an analog-to-digital for converting an analog signal received from the RF front end unit into a digital signal and a digital-to-analog converter for converting a digital signal into an analog signal and providing the converted signal to the RF front end unit, and a baseband signal processor, having a plurality of signal processing modules for processing communication signals and a control module for controlling the signal processing modules installed therein as software modules, for providing cordless phone and handset transceiver functions.

Abstract: An apparatus and method for providing enhanced wireless communications, in which predetermined parameters are obtained by using an experiment in a wireless network environment to decrease traffic backoffs in real-time or increase traffic throughputs in non real-time, and the obtained parameters are used for access points and each station.
