As Figure 1 shows, this functionality is represented by a switch, which enables efficient packet communication among the participating endpoints.
正如图1所示，这个在功能上表示为一个交换机，它支持参与其中的端点间的高效数据包通信。

This is typically used to detect network failures (cable, switch, router, and so on) where the processes stay running but the communication between them fails.
这通常用于检测网络故障(电缆、交换机、路由器，等等)，其中进程仍然运行但它们之间的通信失败。

A single network, a LAN or a switch, is used for GPFS communication, including the NSD communication.
