笔记：conversions topology in MOSS 2007

MOSS 中 2007 转换拓扑关联2个主要的服务：

1、Document Conversions Launcher Service.(启动服务)

2、Document Conversions Load Balancer Service.（负载平衡服务）

Below is the steps:

1. A user or service requests a conversion of type "A." The Web application asks the Document Conversions Load Balancer Service for an available launcher.

2. The Document Conversions Load Balancer Service returns a URI for the most available Document Conversions Launcher Service.

3. The Web application sends the conversion request to the available Document Conversions Launcher Service.

4. The Document Conversions Launcher Service runs Converter A and notifies the Web application when the conversion is done.

5. The Web application notifies the Document Conversions Load Balancer Service that the conversion is complete, making it available for new requests.

在最基本的文档转换拓扑单一的应用程序服务器包过文档转换启动服务和文档转换负载平衡服务器以及转换程序（看下面的拓扑图）。以及需要应用程序对文档的转换分开拓扑图也如下：

要是在服务器场的环境的那就不一样了，那必须得知道是哪台服务器是启动转换服务哪台是进行负载平衡服务。
