交换机在其交换表中查找目标MAC地址，确定交换机出端口，通过该端口将帧转发至目的地。

The switch looks up the destination MAC address in its switching table, determines the outgoing interface port, and forwards the frame on to its destination through the designated switch port.

如果有， 它将其转发给 Apache SOAP 引擎，然后此引擎分析 XML 有效载体，并在其本地注册表（启动时从 DeployedServices.ds 文件读入）上使用目标 Web 服务地址来执行查询。

The engine then parses the XML payload and uses the target Web service address to perform a lookup in its local registry (populated at startup when it reads the DeployedServices.ds file).

这样，协议栈将会根据数据包的命令标识符，通过自身的绑定表查找到所对应的目标设备地址。

This will cause the stack to look up the destination in its internal binding table based on the command identifier of the packet.
