The framework architecture is based on a messaging design pattern: framework components are able to interchange information and perform computations by sending, receiving and processing messages.

框架架构基于一个消息传送设计模式：框架组件能够交互信息并通过发送、接收和处理消息执行计算。

youdao

In the request-response pattern, the endpoint (which is the actual web service in this case) sends a correlated message back upon receiving a message from a client that needs a response.

在请求-响应模式中，端点(此时为实际的Web服务)在接收到需要响应的客户机消息时，会发送回一个相关消息。

youdao

This resolving scheme is based on advanced J2EE platform, applies MVC pattern, Session Facade pattern and Data Access Object pattern to control E-mail from two directions of sending and receiving.

该解决方案架构在先进的J2EE平台之上，应用MVC模式、会话模式和在数据访问对象模式等J2EE开发模式，从收和发两个方向对电子邮件进行了有效控制。

youdao

Both sending and receiving stations would, however, need some mechanism to encode and control the frequency-hopping pattern.
