有线电视网络EPON ONU自动认证系统的研究

The Research of Cable Network EPON ONU Automatic Authentication System

在政策激励、宽带提速及光进铜退趋势的推动下,高速数据、超高清点播及OTT等新业务的出现,有线电视网络运营商逐渐开始采用FTTH技术建设双向网络。本文结合原有HFC网络认证系统及光纤到户EPON系统的特点,提出了一种ONU自动认证系统,充分利用已有的LDAP认证服务器及EPON网管,实现了ONU在OLT PON端口的自动认证及ONU业务的自动认证,保障了光纤到户网络业务的快速开通。

With the promotion of policy incentives, broadband speeding-up , fiber-instead-cable operation, some new business like high-speed data service, high-definition VOD and OTT appeared. Cable TV network oper-ators are beginning to adopt FTTH to construct the access networks. According to the characters of HFC authen-tication system and the FTTH EPON system, we propose a system of ONU Automatic authentication, taking full advantage of the LADP and the network management of EPON system, achieving the functions of ONU Automatic authentication in the port of OLT, guaranteeing the FTTH network business developed effectively.
