Abstract


With the Internet increasingly widely used for network performance measurement is becoming increasingly important. The network measuring instruments can effectively help people monitor network status and locate network problems . At present, network performance measuring instrument are the monopoly of foreign companies in the market . Thesis Intel Xscale processor and embedded Linux operating system technology , the successful development of the embedded network performance measurement instrument principle prototype . Papers describe in detail the key technology of the embedded network performance measuring instrument and its solution structure design and its implementation method of the hardware platform , software platform structure design and implementation methods . The paper presents the use of FPGA hardware acceleration technology , network interface throughput as well as improve the system network data processing capabilities approach , an effective solution to the flow in the network performance measuring instrument bottlenecks for data capture and analysis ; paper also proposes an internal clock synchronization method to solve the problem of end - to - end delay measurement clock synchronization . Started paper embedded Linux TCP / IP protocol stack efficiency , analysis of the distribution of the TCP / IP protocol processing time embedded network performance measuring instrument , use FPGA hardware acceleration technology to improve the TCP / IP protocol efficiency .
