网络交换机(英語:Network switch)是一种网络硬件,通过报文交换接收和转发数据到目标设备,它能够在计算机网络上连接不同的设备。一般也简称为交换机。 交换机是一种多端口的网桥,在数据链路层使用MAC地址转发数据。通过加入路由功能,一些交换机也可以在网络层转发数据,这种交换机一般被称为三层交换机或者多层交换机。 以太网交换机是网络交换机最常见的形式。第一个以太网交换机由Kalpana公司(1994年被思科收购)推出。在其他类型的网络中,交换机也普遍存在,如光纤通道、异步传输模式和InfiniBand。 中继器会在其所有端口转发相同的数据,让设备自行判断哪些是自己需要的数据,交换机则不同,它只会将数据转发到需要接收的设备。
