A02B-0078-B501交换是按照通信两端传输信息的需要,用人工或设备自动完成的方法,把要传输的信息送到符合要求的相应路由上的技术的统称。交换机根据工作位置的不同,可以分为广域网交换机和局域网交换机。广域的交换机就是一种在通信系统中完成信息交换功能的设备,它应用在数据链路层。交换机有多个端口,每个端口都具有桥接功能,可以连接一个局域网或一台·性能服务器或工作站。实际上,交换机有时被称为多端口网桥。
网络交换机,是一个扩大网络的器材,能为子网络中提供更多的连接端口,以便连接更多的计算机。随着通信业的发展以及国民经济信息化的推进,网络交换机市场呈稳步上升态势。它具有性价比高、高度灵活、相对简单和易于实现等特点。以太网技术已成为当今·重要的一种局域网组网技术,网络交换机也就成为了·普及的交换机。
Switch是交换机的英文名称,这个产品是由原集线器的升级换代而来,在外观上看和集线器没有很大区别。由于通信两端需要传输信息,而通过设备或者人工来把要传输的信息送到符合要求标准的对应的路由器上的方式,这个技术就是交换机技术。从广义上来分析,在通信系统里对于信息交换功能实现的设备,就是交换机。
