IP技术的发展
产生了大量以以太网技术为基础的接入技术。BPON就是其中之一
并且以其综合的优势被业界寄予厚望
被认为是解决宽带接入“第一公里”瓶颈的最佳方案。然而随着EPON标准化进程的推进
也显现出一些意想不到的问题。由于EPON是基于Ethernet的
在传输实时业务方面带来了不少麻烦。同时EPON采用共享型的拓扑和下行数据广播方式
不可避免地面临安全性问题。本文着重分析EPON所面临的两大主要问题:多业务支持和安全性问题;并在此基础上提出解决这些问题的初步构想。
With the development of IP technology
many access technologies based on Ethernet are come forth
EPON is one of these. EPON
because of its integrated predominance
is deserved so much honors and viewed by many as an attractive solution to the “First Mile” bottleneck. But with the standardization of EPON
a few questions emerge. Since EPON is based on Ethernet
it faces with a few difficulties when it comes to transmit real-time data. At the same time
EPON shares transmitted media and broadcast all downstream data
undoubtedly it confronts with secure problems. This paper presents new challenges faced with EPON: supporting multi-service and security research
and puts forward some novel proposals to solve these two issues.
