Client network traffic metering and billing instrument and using method thereof

Abstract

The invention discloses a client network traffic metering and billing instrument which has the advantages that the client network traffic metering and billing instrument is used for trade settlement, is convenient for national metrological quantity value transmission and consumer monitoring, has a high measurement accuracy, ensures a network efficiency and has a high safety performance; traffic data is difficult to falsify; the network abnormal problems of broadcast storm and the like are reduced; and the manufacturing cost is low. The client network traffic metering and billing instrument comprises a micro control unit MCU, a double-port Ethernet controller, a storage unit, a card reading module, a USB (Universal Serial Bus) communication module and a network interface module; the MCU is respectively connected with the double-port Ethernet controller, the storage unit, the card reading module and the USB communication module by a memory SRAM (Static Random Access Memory)-like interface, an IC2 (Integrated Circuit) interface, an intelligent card interface and a USB2.0 interface; the double-port Ethernet controller is connected with the network interface module or an ADSL (Asymmetric Digital Subscriber Line) module by a RJ45 interface; and the MCU is a STM32 processor on the basis of an ARM Cortex-M3 kernel. The invention also provides a using method.

Description

technical field [0001] The invention relates to a user end network flow metering and charging instrument, and also relates to a method for using the user end network flow metering and charging instrument. Background technique [0002] The measurement of network flow is to measure the flow of data information generated by users on Ethernet, wireless network or other networks. According to the way of realization, it can be divided into hardware realization and software realization. The hardware implementation method can use a dedicated IC or FPGA circuit to analyze and measure the data flow information; the software implementation method uses software to capture network data packets and analyze the frame header of the data packet to achieve the purpose of flow measurement. The measurement of network traffic is divided into the measurement of uplink traffic and the measurement of downlink traffic. The measurement of uplink and downlink traffic includes the statistics and measur...
