基于以太网技术的宽带接入网络

随着宽带网络应用的发展，宽带接入技术成为目前比较活跃的技术领域，一些接入技术已经开始应用，如ADSL、HFC等，但是，这些技术的成本较高，不易被广泛采用。文章主要讨论广泛应用且成本低廉的以太网技术，以及如何将其应用于宽带接入网络，一些面临的问题将被提出。最后提出几种解决方案并得出相应的结论。

Broadband Access Network Based on Ethernet Technology

With development of broadband network application, the accessing technology of broadband network becomes an active area. Some accessing technologies, such as ADSL and HFC, have been used. But these methods do not be used widely due to their high costs. The authors discuss the widely used Ethernet technology and show how it can be deployed in broadband access network, addressing some problems need to face. Several solutions will be given, and conclusions are drawn.
