3.Link-maintenance frames are used to manage and debug a link.
连结维持被用在连结的管理与除错。收藏指正
4.Frame Relay implements no error or flow control. The simplified handling of frames leads to reduced latency, and measures taken to avoid frame build-up at intermediate switches help reduce jitter.
中继本身并没有实作错误控制或流量控制。这个被简化的控制可以导致延迟降低,且在量测上避免塞满在中间的交换器帮助降低信号剧跳。收藏指正
5.When Router Y sends a frame to Host X, Switch A and Switch B also receive the frame and will send it out port 1.
然后当路由器Y要传送一个到主机X,交换器A和交换器B也会同时收到这个,并将送它从埠1传送出去。收藏指正
6.The frame to Router Y is flooded on port 1 of both switches.
这个传送到路由器Y的会被泛流到这两台交换器的埠1。收藏指正

8.With increasing demand for higher bandwidth and lower latency packet switching, communications providers introduced Frame Relay.
因为较高的频宽及较低延迟的分封交换的需求增加,通提供者引入了中继。收藏指正
9.The data link layer builds a frame around the network layer data so the necessary checks and controls can be applied.
资料链结层在网路层资料之外建立一个,如此一来必要的检查和控制才能被套用。收藏指正
