A gateway is a part of a message bus or service bus which provides boundary functions which apply to all incoming messages and are not format dependent.
网关是消息总线或服务总线的一部分，提供应用到所有传入消息且不依赖于格式的边界功能。
Enterprise Service bus (ESB) is a standard software architecture based on an event-driven messaging engine, of which message bus is the foundation.
企业服务总线(esb)是基于事件驱动的消息传递机制的标准软件架构，消息总线是ESB的基础。
Upon receiving a message from the message bus, these components call out to a remote Web services endpoint, notifying it that a message has been received.
从消息总线上接收消息，这些组件唤醒远程Web服务端点，通知它已经接收了消息。
Then a set of adapters act as gateways between a protocol like e.g. SOAP over HTTP, email, FTP, RMI on the one hand and the message bus on the other hand.
一组适配器充当协议(例如SOAP overHTTP、email、FTP、RMI)和总线之间的网关。
So an ESB is better than a traditional message bus because it also makes a service self-describing and provides a directory service for finding the other services.
所以esb比传统的消息总线要好，因为它还使得服务可以自描述，并且提供了用于查找其他服务的目录服务。
An asynchronous messaging system typically relies on a message bus or broker to expose queues or event channels that receive messages published by message producers.
异步消息传递系统通常依赖于消息总线或消息代理公开用于接收消息生成方所发布的消息的队列或事件通道。
Listing 3 shows the code for one of two listeners that receive the CaseModel delivered through the message bus and convert the provided text to upper and lower case.
