摘　　要：针对无源光网络(PON)国际标准未就复合光网络单元(ONU)系统中软件镜像远程升级方法进行详细规定的情况,设计了一种复合ONU软件镜像的远程升级方法。该方法在满足国际标准的基础上进行了扩充,具体包括:设计了可包含多镜像文件的复合镜像文件格式和制作方法,并开发了基于以太网协议的带外管理和文件传输协议(用于高效传输镜像文件);同时,考虑了对多种国际/国内标准协议的兼容性。实验结果表明,所提远程升级方法功能有效,效率高。In view of the fact that the international standard for passive optical network(PON)has not specified the method of remote software image upgrade for the composite optical network unit(ONU)system,a remote software image upgrade method for composite ONU is designed.The method expands upon the international standard while meeting its requirements,including the design of a composite image file format that can contain multiple image files and the method of creating such files,as well as the development of an ethernet-based out-of-band management and file transfer protocol(used for efficient transmission of image files).At the same time,the method is compatible with a variety of international/domestic standard protocols.The experimental results show that show that the proposed remote upgrade method is functionally effective and highly efficient.
