毕业论文：GPON技术在智能小区三网融合中的应用实践.doc

硕士学位论文 GPON技术在智能小区三网融合中的应用实践 摘要 本文以当今的热门技术三网融合为中心，首先介绍了何为三网融合，其次分析其发展的意义、现状以及对未来发展的展望；接下来提出了一个重要的问题：“三网融合”究竟融合于哪一张“网”？引出了对NGN，也就是下一代网络的探讨，阐述了三网融合在NGN网络中的网络层次的划分，以及各层次的职责和作用；然后结合作者在华为技术有限公司将近一年的实习工作经验将重点放在接入网侧，也是最接近用户的网络，详细的介绍了何为“接入网”，并选取接入网络目前比较成熟和先进的GPON技术作为切入点，介绍了GPON的技术原理，以华为公司的三网融合解决方案为案例，介绍了三网融合所需的硬件、关键技术和实现原理，具体的实施流程，业务实现以及发放流程，环境的搭建和配置。整篇文章采用总-分-总的整体写作思想，阐述了我在参与相关工程案例之后对GPON技术在三网融合当中应用的理解与认识。 关键词：　三网融合， NGN，接入网，GPON，解决方案Abstract The article concentrates on a popular technology nowadays –“Triple Play” .At first it introduced what is the triple play, followed by an analysis of its development significance, current situation and the prospect of future development .Then raises an important question: triple play is inclusive in which a net? Leads to the NGN, also is the next generation network discussion, elaborated the network convergence in NGN network hierarchical classification, as well as various levels of responsibility and role; and then combined with the author in Huawei Technologies Co. for nearly a years work experience , it focus on the access network side, also the closest to the user’s network, introduced in detail what the access network, and select the access network are relatively mature and advanced GPON technology as a starting point, the principle of GPON technique, with Huawei convergence solutions as a case, introduced triple play the required hardware, the key technology and realization principle, specific implementation process, service realization and distribution process, environment set up and configuration. This article uses the total –distribution- total writing method, set out my understanding and awareness about the application of GPON technology in Triple-play after participated in the engineering case.
