| 摘 要： | 如何快速稳定地对数量众多的ONU进行软件升级是EPON系统面临的一个重要问题,文章提出一种实现ONU软件批量升级、定时升级和自动升级的方法,它由OLT通过OAM协议发启ONU升级事件,然后ONU主动通过FTP(文件传输协议)完成文件下载、数据校验和程序烧写等操作步骤,同时OLT还需监控、维护和管理ONU软件升级的状态.

| Abstract: | How to quickly and steadily to the large number of ONU software upgrade is EPON systems are faced with an important issue, this paper presents an implementation of the software volume ONU upgrades, regular updates and automatic upgrade method, the upgrade event is issued by OLT, then the ONUs download the software binary file through FTP (File Transfer Protocol) and burn the FLASH ROM initially, OLT is re-sponsible for state machine maintance of all the ONUs. |
