设计模式在CORBA系统中的应用

The Application of Design Pattern in CORBA System

ORB核心(ORBCORE)是CORBA(通用对象请求代理体系结构)的重要组成部分,而对C/S两端的连接及事件分派的管理是ORB核心设计中的重点。优化的连接管理和事件分派机制将极大地提高ORB核心的效率及其可扩展性。该文提出了使用Dispatcher设计模式(DesignPattern)来管理ORB核心中C/S两端的连接及事件分派的思想,叙述了Dispatcher模式的原理,并给出了使用该模式来管理连接和事件分派的具体实现。

ORB core is the most important and fundamental component of CORBA(Common Object Request Broker Architecture).And the management of the connection between the C/S and events dispatching is the most important in ORB core.So an optimized mechanism of the connection and event dispatching will greatly affect the performance of an ORB core.This paper discusses that the ORB core could be built with Design Patterns including Dispatcher Pattern.It also discusses the working mechanism about how the Dispatcher Pattern manages the connecting and event dispatching between C/S.The paper describes the implementation of important parts and key procedures of the ORB core which is built with the Dispatcher design pattern.
