需要使用应用程序网关(适配器)与服务的提供者或使用者进行连接。

The application gateway (adapter) is needed to interface with the provider or consumer of a service.

一组适配器充当协议(例如SOAP over HTTP、email、FTP、RMI)和总线之间的网关。

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.

如果无法到达这个网关，那么从您主机上的网络适配器到网关的物理连接可能有问题（例如交换机端口、线路和网卡有故障）。

If it isn't, there may be a problem with the physical connection from the network adapter on your host to the gateway (for example, a faulty switch port, cable, network card).
