Research And Design Of Grid Communication Network Resource Management System

Grid is essentially an emerging computer infrastructure, and it is calledthird-generation internet. Grid can integrate a variety of wide-area distributed scatteredresources geographically, providing more powerful features. Grid network resources aredistributed, heterogeneous, dynamic and autonomous, how to network resources foreffective management of the grid system is an important prerequisite to the application.Network resource management is divided into discovery monitoring, scheduling andcontrol of resource, the major of this subject is to research discovery and monitoring ofresource.Firstly, the characteristics of the grid network is briefly introduced, and newmanagement needs and characteristics are described under the grid environment, analysisgrid services webservices protocol stack, framework and the calling process combing withWebService technology. Then grid network resource discovery mechanisms have beenstudied and analyzed, combined with a grid network resource organization anddistribution, proposed a hierarchical model of distributed, cross-domain resourcediscovery resources in network of small-world, the resource discovery in the grid networkis divided into domain lookup and inter-domain lookup, thereby reducing the lookup space.According to the algorithm analysis between domain lookup and inter-domain lookup, thetraditional inter-domain lookup, the traditional inter-domain resources discovery based onflood has large many shortcomings, such as redundant message, high bandwidth and longdelay. So the resource discovery algorithm (Rumor algorithm) rumor mechanism based onis introduced into the resource discovery model, the theoretical analysis confirmed thatRumor algorithm can effectively reduce the inter-domain messaging blindness andimprove the efficiency of resource research. Finally, with WebService technology basedon the Apache CXF to achieve the grid network resource management, mainly solve thecross-domain resource discovery and access, experiment results showed that privilegedusers can use a web browser or other application program visit the portal server to accessgrid network resource management services, to achieve intergrated management toheterogeneous network.
