因为每次修改的元数据都被完全复制到每个服务器节点中，所以读取元数据通常只要在一个节点本地进行，而不需要网络通讯。

Since changes to the metadata cache are replicated to every server, a read is always local and doesn't require network communication.

比如说，您可以将各节点的输出嵌入到一个图像文件中并将其存储在 Web 服务器上，以供网络的下一层获取。

For example, you could have the output of each node embedded in an image file and stored on a Web server, ready to be fetched by the next hop in the network.

RADIUS客户机是网络访问服务器，它通常是一个路由器、交换机或无线访问点(访问点是网络上专门配置的节点；wap是无线版本)。

The RADIUS client, the network access server, is typically a router, switch, or wireless access point (access points are specially configured nodes on networks; WAPs are wireless versions).
