There are two basic types of switching techniques: circuit switching and message switching.

交换技术有两种基本类型：电路交换和报文交换。

This paper introduces the idea of logic integration, and presents the architecture of an aero-message switching system, which is the application level gateway.

本文引入逻辑集成的思想，提出了民航电报交换系统这个应用级网关的体系结构。

This paper analyses the average communication delay of circuit-switching, message switching, packet-switching, virtual cut-through and direct-passing and, the average response time of direct-passing.

对线路交换、消息交换、包交换，虚拟旁通和直通的平均通信延迟时间以及直通的平均请求响应时间进有了分析。

Part 7: Message protocol switching revisited.

第7部分：消息协议切换回顾。

This sort of bold party switching would not only send the message that you think your own side is bereft of talent. It would also create a huge problem with succession.

这种大胆的跨党之举不仅会让人感觉自己认为本党内人才不足，还会在继任问题上造成大麻烦。
