摘要

SDN（软件定义网络）、NFV（网络功能虚拟化）和云计算技术已成为当前的研究热点。研究如何利用SDN、NFV技术和云计算实现vOLT（虚拟OLT），以解决传统PON（无源光网络）OLT运维难度高、资源发放不灵活、业务开通流程复杂等问题。总结了业内 4 种不同的 vOLT 实现方式，同时从电信运营商的立场出发，从应用场景和引入难度等角度对比分析了这 4 种方法，并给出了 vOLT 的演进路线。该研究成果对运营商有一定的参考价值和借鉴意义。

Abstract

SDN technology

NFV technology and cloud computing technology have been studied widely recently.How to realize vOLT based on these three techniques mentioned above was studied in order to solve theproblems that the OLTs of traditional PON faced

such as the OLTs of the PON were too difficultto operate and maintain

the resources allocation including ports

VLAN

MAC and others were not flexible

and theservice provisioning process was complicated.Four vOLT schemes were proposed.From the perspectiveof telecom operators

these four methods were compared and analyzed from the perspectives of application scenariosand the difficulty of introduction.Finally

the evolution route and the development trend of vOLT were conclued.
