为优化学校虚拟实验平台功能，以其网络化改进方向为目标，设计与实现虚拟实验平台的动态升级模块。现有的虚拟实验平台不具有任何网络功能，所能进行的实验内容也相当有限，更重要的是实验内容的更新也是一大问题。该动态升级模块以现有的虚拟实验平台程序为基础，通过向目标主机查询是否拥有本机所没有的实验内容，如有则由用户决定是否下载，另外查询目标主机实验内容的版本号，与本机版本相比较，判断是否为新版本的实验内容，最后由用户决定是否更新。

关键词：虚拟实验平台；版本；动态升级。

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

In order to optimize the function of the virtual experimentation platform and with the aim of its network amelioration, we design and realize the dynamic update module of the virtual experimentation platform. The experimentation platform which we already provided with don’t have any network function and it has few of the experiment we need, besides the update of the experimentation platform is the most important problem. This dynamic update module is based on the program of the dummy experimentation we already provided with, we search the host computer whether has the experiment we don’t have and decide to download the new experimentation or not by the user. On the other side, we search the version of the experiment of the host computer, compare with the version we already provided with and decide to update or not.

Key words: virtual experimental platform; version; dynamic update.
