很多用户在交换机和路由器上都会分别不清,虽然它们的外形特别的相似,但是功能却是天差地别的不同,今天,小编就把路由器和交换机的区别介绍给大家,一起来看看路由器的介绍与交换机有什么不同吧。
路由器和交换机的区别
一、交换机
首先我们要知道交换机它是一种基于MAC设备,能完成封装转发数据包功能的网络设备,它能够学习MAC的地址,将其存放在内部地址表当中,通过数据帧的始发者和接收者建立临时的交换路径,是数据帧直接由源地址到达目的地址。
二、路由器
路由器也被称之为选径器,是网络层实现互联的设备工具,相比于网桥,它会更加的复杂,也拥有更大的活性,本身具有强大的异种网互联能力,可以连接对象包括局域网和广域网。在过去那段时间,路由器多用于广域网,近年来随着性能有很大的优化,在价格上与网桥差不多,因此在局域网互联中也会频繁的使用路由器。
两者区别
1.路由器可以给我们的局域网自动分配ip地址,虚拟拨号,自己不用过多的操作,二交换机只是用来分配网络数据的。
2.路由器在网络层,根据ip地址寻址,能够处理TCP/IP协议,交换机则不行,交换机在中断层,根据MAC地址寻址。
3.在路由器上有提供防火墙的服务,交换机没有这项功能。集线器,交换机都是做端口扩展的,也就是扩大局域网的接入点,简单来说就是可以让局域网当中连接更多的电脑,二路由器是用来做网间连接,用来连接不同的网络的。
以上就是路由器和交换机的区别所在,希望可以给大家提供帮助。
