DCOM技术在网络虚拟实验室中的应用

DCOM Application in Virtual Electronic Laboratory for Distance Education

为了使虚拟实验室适合远程网络教学的需要,使它能够在网络上工作,利用DCOM技术,以C/S(Client/Server)方式实现了组件化的虚拟实验室。将模拟计算部分作为服务器,界面输入/输出作为客户。在多用户的情况下,DCOM没有提供分布式策略,则利用调度对象来平衡负载,从而引入分布式处理方式。

As a software for distance education, Virtual Electronic Circuit Laboratory must be able to work over network. This paper implemented Virtual Electronic Circuit Laboratory for distance learning based on DCOM. Athough DCOM provides no distributed solutions to serve multiuser, but a COM object is used to dispatch the requests from users to specific objects.
