| Abstract: | In view of the IP carrying network structure and technical characteristics, this paper firstly proposed a system framework of the FPGA-based IP carrying network emulator which combined with the current situation and requirements of network performance testing .Then researched a way to emulate the packet loss rate based on the FPGA.Finally, the design idea of the emulator hardware module is discussed in detail. The result of the simulation test shows that the system has a good application foreground. |
