基于网络技术的飞速发展和广泛应用,本文阐述了网络接入方式的几种技术,并重点对比了路由器和交换机的接入方式。接入方式改变的技术基础1二层交换技术二层交换机作用层次是数据链路层,其读取数据包之后,根据交换机内部的MAC地址表来进行交换,这个地址是MAC地址和交换机端口的映射关系。具体交换流程如下:接收到数据包之后,嵌入在包头之中的源MAC地址和目的 MAC地址分别被读出,交换机由此
Based on the rapid development and widespread application of network technologies, this paper describes several techniques for network access and focuses on comparing the access methods of routers and switches. Access to change the technical basis 1 Layer 2 switching technology Layer 2 switch role level is the data link layer, which reads the data packet, according to the switch internal MAC address table to exchange, the address is the MAC address and switch port Mapping relations. The specific exchange process is as follows: After receiving the data packet, the source MAC address and the destination MAC address embedded in the header are respectively read out, so that the switch
