Synchronous and asynchronous communication techniques to support the transporting of low volumes of changed data could occur within the Connectivity and Interoperability Layer.

支持传输少量数据的异步和同步通信技术可以在连接和互操作层中实现。

Lack of support for the asynchronous communication model can have an impact on client-side development, integration with Web frameworks, use of tag libraries, ide use, and threading behavior.

对异步通信模型支持的缺乏，会对客户端开发、与Web框架的集成、标记库的使用、IDE的使用以及线程的行为有影响。

We would use service Interface (collaborating) if the service will also require consumers of the service to provide one or more operations, perhaps to support asynchronous communication.

如果服务同样需要服务的消费者提供一种或多种操作，例如用于支持异步通信，则应使用Service Interface (collaborating)。
