Abstract: A system detection method and apparatus. Throughput and response time of a system are acquired. Throughput reflects the number of requests processed by the system that are received from outside the system. The response time reflects time required to process requests from outside the system. A system performance characteristic parameter based on the throughput and response time is obtained and used to describe congestion of the system to determine bottlenecks in the system by at least obtaining system performance characteristic parameter based on the throughput and the response time and conducting noise filtering on the system performance characteristic parameter. A bottleneck is determined based on the noise filtered system performance characteristic parameter. The system detection method and apparatus allow detecting a bottleneck and flow control are provided in a simple and effective way to ensure that requests are processed in time.

Abstract: A non-transitory computer program product with computer readable program code for system detection and flow control. The throughput and response time of the system are acquired, where the throughput reflects the number of requests from outside the system that has been processed by the system. The response time reflects time required by the system to process requests from outside the system. Acquiring throughput and response time includes directly sampling the throughput and the response time of the system; and conducting noise filtering on the sampled throughput and response time. A system performance characteristic parameter based on the filtered throughput and response time is obtained and is used to describe congestion condition of the system to determine whether there is a bottleneck in the system. Detecting a bottleneck and flow control is provided in a simple and effective way to ensure that requests are processed in time.

Abstract: A dielectric chip antenna includes a substantially rectangular parallelepiped dielectric substrate, a feeding electrode, a fixation electrode, and two radiation electrodes. The feeding electrode is provided on one longitudinal end surface of the substrate, and is used to receive high frequency energy to be transmitted. The fixation electrode is provided on the opposite longitudinal end surface of the substrate and is used for fixation of the antenna to a printed circuit board. The two radiation electrodes are formed on a peripheral surface of the substrate so as to extend longitudinally while spirally surrounding the substrate. The base ends of the radiation electrodes are connected to the feeding electrode. The two radiation electrodes are formed symmetrically with respect to a horizontal plane passing through a center axis of the substrate so that the two radiation electrodes are of identical patterns on the upper and lower surfaces of the substrate.
