Question

我对我如何配置与外部系统相联的系统存在疑问。

Here are the various parts, which I was thinking of putting together:

<><>>>>

I have 3 external services which brings in 3 different types of messages to the system.
I have a WCF service which listens to all these external services, which converts the messages into a common format.
I have a WPF UI which is connected with the WCF service using duplex tcp binding, and messages gets updated on the UI.
The UI also sends any outgoing messages to the service which in turn sends it to the external services.

我的问题是,你是否认为这是设计解决办法的一个可衡量、可维持、成本有效的方法? 如果我把这个问题放在内联网的设想中,你是否看到任何具体问题?

我提出的另一项考虑是:

<><>>>

Have 3 windows services which connects to the external services.
Each service churns out the messages into a canonical format and puts it on a message bus on a specific topic.
Have a WCF service which listens to the topics on the message bus for the new messages.
Use a duplex binding to update the client with any incoming messages.
Client sends the outgoing messages to the WCF service, which in turn drops it on to a specific topic listened by the windows services, which sends them to the external systems.

我在这里感到困惑不解的是,请你帮助我了解什么是更好的办法,如果你能够,请让我指出讨论这些情景的任何联系?

Volume of data exchange is 400 messages every 5 minutes, divided across the external systems.

I m sure lot of you might have faced this situation, so if you have a better approach to this please let me know.

Thanks, -Mike

我当然认为,在处理3种类似但不同的信息格式时,你的选择2是正确的。采用了两种融合模式:adapter 和。

然而,我认为,将同样的“航道”服务作为向相反方向传递信息的渠道是错误的。最好把答复渠道从请求处理管道中抽出。

您可采用一种分配模式(或 router),处理回复信息回请求来源的路径。
