Information Flow Meter Design And Realization

With the rapid development of Internet, the data traffic is facing with communications traffic press that ever meet, the network measure is regarded in technology layer and business aspect. Contraposing the measure's weaknesses of unified background measure by telecom dealer, the thesis develops the "Measurement Meter for the Network Traffic".The thesis studies the measure techniques of the traffic and the realization techniques of the "Measurement Meter for the Network Traffic" deeply. First, the thesis studies the classification and the monitor techniques of network traffic. It also analyzes the measure methods and the capture methods of the network traffic. Second, the thesis designs the system frame of the "Measurement Meter for the Network Traffic". The thesis expounds the structure of the traffic measure unit and makeup of subschema. The thesis also brings forward the measure arithmetic of network traffic. Third, contraposing the realization of the "Measurement Meter for the Network Traffic", the thesis discusses the difficulties of realization techniques of the FPGA, puts forward the ways of realization. At last, contraposing the validity design and dependability design of the "Measurement Meter for the Network Traffic", the thesis design a flat roof of function emulation to test the validity of the function of the "Measurement Meter for the Network Traffic". The result of the flat roof improves that the measure is exact and the design is up to the mustard.The thesis adopts FPGA technology to develop the "Measurement Meter for the Network Traffic". It can adapt the traffic measure and be used between the user's port and telecom network. It is a sort of network measure equipment which is convenient,simple,shortcut and widely used.
