通过研究分析RMI(远程方法调用)技术,设计了服务网关中间件来统一地透明地访问和调用不同类型的分布式计算服务。首先分析了分布式计算技术的公共特征RMI;其次提出了服务网关中间件模型的框架和运行机理;进而提出了服务代理、通信管理、协议配置、远程引用管理、服务骨架和调度、服务类型适配以及服务信息注册各个模型的实现技术与方法。服务网关中间件高效地利用了资源,解决了信息处理的“孤岛”问题。 Through research and analysis of RMI (Remote Method Invocation) technology, Service Gateway Middleware is designed to transparently access and invoke different types of distributed computing services. Firstly, it analyzes the public feature RMI of distributed computing technology. Secondly, it proposes the framework and operation mechanism of service gateway middleware model. Then, it proposes service proxy, communication management, protocol configuration, remote reference management, service skeleton and scheduling, With service information registration and implementation of the various models of technology and methods. Service gateway middleware makes efficient use of resources and solves the “islanding” problem of information processing.
