It is necessary to monitor the usage of network resources in the core network, and give the solution to avoiding network congestion problems. Congestion control method in Huawei's routers and switches is analyzed. Based on it, then a real-time network traffic analysis and quality of service management platform was designed. With four-tier architecture and five functional modules, the platform achieves...
The time-triggered principle establishes and maintains a system-wide synchronized time-base by the local clocks of the device. The proposed concept of Time-Triggered Ethernet (TTE) guarantees the determinacy of time-critical message for avionics and safety-critical systems. This paper presents an algorithm based on path-hop of tasks to generate a rational scheduling timetable to ensure is free of...
Memory bandwidth is critical to GPGPU performance. Exploiting locality in caches can better utilize memory bandwidth. However, memory requests issued by excessive threads cause cache thrashing and saturate memory bandwidth, degrading performance. In this paper, we propose adaptive cache and concurrency allocation (CCA) to prevent cache thrashing and improve the utilization of bandwidth and computational...
Partial discharge (PD) measurement method defined in IEC60270 only captures the low frequency energy of measured signals, while more than 95% of the energy is distributed in the range of 30kHz∼30MHz. Thus a high frequency wide band measurement method becomes fashionable to cover the entire bandwidth. In such frequency range, the influence of stray inductance and capacitance become dominant, especially...
