The capability of network bandwidth to characterize network traffic information is one of the important indices for measuring network service quality. In order to realize the low cost of network digital bandwidth measurement and the demand of the network, this paper proposes a network digital bandwidth measurement monitoring system based on embedded system design and implementation method, based on the Ethernet as the foundation, by the bandwidth measurement module, adopt MIC29302BU chip as the core of the power supply module, block based on the EEPROM chip network access module, the embedded network digital surveillance system self-checking module and analog-to-digital conversion module, analyzed the system of network digital bandwidth measurement process and the realization of the specific program code. The experiment results show that the monitoring system to achieve the accurate measurement of mass digital bandwidth, and has high efficiency and accuracy of monitoring.
