Abstract: A portable network performance measurement device is designed and implemented, in which Intel XScale PXA255 microprocessor and embedded Linux operating system are used. The FPGA device is applied to miniaturize the measurement device and to enhance its performance. The key techniques to solve the problems such as synchronization among devices, data exchange between network interface and CPU, data analysis and visualization are discussed.

Key words: network measurement device, synchronization, visualization, XScale, embedded Linux
