A LAN switch is a device that provides much higher port density at a lower cost than traditional bridges. For this reason, LAN switches can accommodate network designs featuring fewer users per segment, thereby increasing the average available bandwidth per user. This chapter provides a summary of general LAN switch operation and maps LAN switching to the OSI reference model.
Figure 26-1 illustrates a LAN switch providing dedicated bandwidth to devices and illustrates the relationship of Layer 2 LAN switching to the OSI data link layer.
參考答案:局域网交换机是一种装置,提供更高密度的港口以较低成本比传统桥梁. 为此,兰开关网络的设计可容纳用户少,每部分 从而增加平均每用户可用带宽. 本章概述了一般兰图兰切换开关的操作和OSI参考模型. 图26-1说明了局域网交换机提供专用的带宽来显示装置和2层关系交换局域网数据链路层的互连.
