Research And Implementation Of Distributed Campus Information Service Platform

Today, twenty-first Century, is the development of information technology flourishingage, now the human, is an unprecedented high dependence on information technology,computer technology and network technology, hitherto unknown. In order to solve thetraditional, single server provides a single service model in energy consumption, businessexpansion, stability and other aspects of the defect, emerge as the times require distributedprocessing technology. In this paper, based on RBAC control permissions caching service,distributed campus information service platform is designed and realized, using distributedin different locations of the data processing node, collaboration. The main work is as follows:1) the existing system and the new development system using distributed processingtechnology to transform, the system integration is a large, stable, internal interactivedistributed system, in order to improve the performance and stability of the overall processingsystem. Pointed out that the current environment, hybrid interior business system of collegesand universities, the data island phenomenon seriously, low utilization rate of resources, highenergy consumption and shortcomings, put forward operating base distributed softwareplatform, and provide solutions for interactive platform level of data sharing and subsystems.2) proposed three layer service architecture to "core data service layer, infrastructureservice layer, service layer" as the core. Through the program, so as to realize the interactionand data between the application development platform based on sharing. In between theplatform of each system data exchange and sharing mode, in the manner of distributed systemhas fully studied SOA service oriented architecture, this paper proposes to create a designscheme of JMS ESB based on service bus, the service bus, to realize data sharing betweenthe subsystems, data interaction and asynchronous remote service invocation etc..3) the basic concept, concept of certification of RBAC access control model and nonrelational database characteristics, and the range of its application, in the process of core dataservice layer design of information service platform in, this paper proposes to NoSQLdatabase as the core data persistence scheme of RBAC access control model, and successfullythe design scheme of the practice. In the realization of the core data service layer, accesspressure to reduce the core data service layer data, carefully study the relevant content aboutthe Memcached distributed cache service cluster, including the basic concepts, applications,cache service characteristics, consistent hashing algorithm and other related content, thispaper designs and implements the service based on the Memcached cache. According to themonitoring data, use of cache service, obviously reduces the core data service itself to readthe data frequency, at the same time, because of the characteristics of high speed MemcachedII itself has, but also enhance the core data access speed.4) finally, based on the above research results to realize distributed campus informationservice platform, and deploy the use of virtualization technology, improving the utilizationrate of resources, reduce the cost. At present, the platform stable operation.
