人们想通过相同的接入设备来连接到远程站点上的多个主机，同时接入设备能够提

供与拨号上网类似的访问控制和计费功能。在众多的接入技术中，把多个主机连接

到接入设备的最经济的方法就是以太网，而PPP 协议可以提供良好的访问控制和计

费功能，于是产生了在以太网上传输PPP的方法，即PPPoE。

PPPoE协议的提出解决了用户上网收费等实际应用问题，得到了宽带接入运营商

的认可并广为采用-People want the same access device to connect to multiple hosts at a remote site, while the access device to provide dial-up Internet access control and billing similar functions. Among the many access technologies, multiple host connections to the most economical way to access device is Ethernet, but PPP protocol provides good access control and billing functions, so have the PPP over Ethernet transmission method that PPPoE. PPPoE protocol proposed to solve the practical problems of user access fees, get broadband access operators recognized and widely used
