Design And Implementation Of Resour CE Management And State Polling SYS TEM For Large Network Experiment Platform

With the rapid development of the Internet, network planning, application and the design of protocol faces new challenges. Evaluat e the network planning, the new application and agreement in the e nvironment, is the effective means to meet the challenge. Therefore establishing large network experiment platform to provide the netw ork experiment environment, which is reconfigurable, high lifelike, r eproducible and can be expanded, is the best way to do exploration and study on the future network.This subject adopts OpenFlow technology, design and realize it s resource management and condition monitoring system base on se t up the network environment of experimental platform completely. Unified management all resources fo test bed such as the node,swit ches and routes,and real-time monitoring its state. In addition,feedba ck the results with the form such as graphics, list to the system ad ministrator.The paper firstly introduces the current world network experim ent platform development present situation, and the basic concepts o f OpenFlow network, NOX, virtualization technology and XML tech nology. And then the paper expounds the system structure of the re source management and state polling system on the large network e xperiment platform, and briefly introduced the switch inquiry modul e, flow management module, topology query module, data processin g and front display module. After that, the paper give a detailed de scription of the principle and realization method of each module, an introduction of the data structure and function, and the necessary narrative of the module functions processe. Finally, this paper summ arized the research work and look forward to the future work.
