6GK5786-1FC00-0AA0以太网交换机

6GK5786-1FC00-0AA0随着计算机及其互联技术（也即通常所谓的“网络技术”）的迅速发展，以太网成为了迄今为止普及率·高的短距离二层计算机网络。而以太网的核心部件就是以太网交换机。 

6GK5786-1FC00-0AA0不论是人工交换还是程控交换，都是为了传输语音信号，是需要独占线路的“电路交换”。而以太网是一种计算机网络，需要传输的是数据，因此采用的是“分组交换”。

6GK5786-1FC00-0AA0但无论采取哪种交换方式，交换机为两点间提供“独享通路”的特性不会改变。就以太网设备而言，交换机和集线器的本质区别就在于：当A发信息给B时，如果通过集线器，则接入集线器的所有网络节点都会收到这条信息（也就是以广播形式发送），只是网卡在硬件层面就会过滤掉不是发给本机的信息；而如果通过交换机，除非A通知交换机广播，否则发给B的信息C绝不会收到（获取交换机控制权限从而监听的情况除外）。 

6GK5786-1FC00-0AA0以太网交换机厂商根据市场需求，推出了三层甚至四层交换机。但无论如何，其核心功能仍是二层的以太网数据包交换，只是带有了·定的处理IP层甚至更高层数据包的能力。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。它具有性能价格比高、高度灵活、相对简单、易于实现等特点。
