Research On General Framework Of Distributed Network Resource Register System

In recent years,along the fast development of the current computer technology as well as the Internet,one hand,more and more network resources in areas like information,service,computing,memory are extremely needed in solving the increasingly complicated practical problems,and because of the limited serving capacities of servers,the traditional C/S(Client/Server) centralized serving mode can no longer meet the various requirements of the large-scale network users;on the other hand,with the continually improving of the personal computer's capacities on computing,memory as well as information processing,we hope that we can share our own resources on the Internet,so as to build the own server to release its own resource sharing services.This paper designs and realises a general framework for Distributed Network Resource Register System(DNRRS).The central server is only responsible for keeping the related information of the network resources, rather than providing specific business services,and resource sharing as well as using is achieved by the communication between providers and users through the system network resource information platform. Resource information registration,publishment and the concrete practical service are functionally separated,the separation not only makes the best of the widely distributed resources in the network,but also makes users can employ services more abundant and powerful.This paper mainly focuses on the tasks as follows:(1) to establish a unified description model for network resource xml Schema,in order that different types of network resources can use the xml language along the specification to describe the critical information to found a base for building the DNRRS framework;(2) to achieve the effective management of distributed network resources information,so that resource providers can neatly and efficiently register,logout,modify and manage its sharing resources, while users can intuitively and conveniently view and query the information resources issued;(3) to put forward a method called DNRASA,it integrates users requirements,capacities of resources host servers as well as its dynamic loads to realize the network resource allocation and scheduling, promoting DNRRS system's load balancing and the performance optimization;(4) to realize the prototype of DDNRRS according to the distributed Network Resource Model(NRM) definition as well as DNRRS architecture design.
