The Research And Design Of A Network Tester On The Basis Of Embedded Technology

With the increasing complex of the network environment, as soon as the faults appear, it is very hard to eliminate only relying on the experience of Network administrators. How to conveniently search the problems of network faults, the real-time track of the applied situations of network resource, the solution to bottleneck of network transmission depend on whether the measuring instrument can discover and isolate the problems with high speed . Therefore, the selection and development of testing tools in the process of operation and maintenance have become a key issue.This paper studies the embedded technology, the C8051F340 processor and the TCP/IP protocol with emphasis. Proposing one kind of design of network termination reflector based on the embedded technology. Based on the knowledge of the TCP/IP protocol's structure and the embedded client side, it also designs from the hardware and the software aspects. This client side hardware selects 8 MCU C8051F340 and turns on Ethernet through the Ethernet controller CP2200, then inputs the testing information which need to dispose manually through the keyboard, and the testing results to the LCD, finally feeds back to the personnel. The software part selects the embedded technology; the application procedure uses the C language modulation design, and unifies the CP2200 programmable chip.
