摘　　要：ONU作为GPON的重要组成部分,直接为用户提供语音、数据、视频等多业务流,对ONU业务层软件架构的研究有重要的现实意义。在分析ONU管理配置协议和数据模型规范的基础上,设计了一种面向数据的ONU业务层软件架构,并对其在应用过程中遇到的问题进行总结分析,继而提出一种层次更加清晰的面向功能的ONU业务层软件架构优化方案,两种方案都先后大规模应用于各类ONU产品,证明了设计的有效性和合理性。As an important part of GPON system, ONU provides users with multiple service flows such as voice, data and video. It has important practical significance to research ONU application layer software architecture. On the basis of analyzing ONU management configuration protocol and data model specifications, a data-oriented ONU application layer software architecture is designed, after analyzed the problems encountered in the application, and then an optimized and functionality-oriented solution is proposed, both solutions have been applied to various types of ONU products on a large scale, which proves the validity and rationality of the design.
