This work provides a techno-economic evaluation of optical disaggregation architectures in the context of metropolitan area networks. The study compares two optical disaggregation options (partial vs. total) against the legacy benchmark where optical equipment is subject to vendor lock-in, as it is deployed in most networks today. We show that emerging open source software projects within the software-defined networking ecosystem can potentially yield significant cost savings for medium- and large-size network operators, while they can introduce extra flexibility and agility to network operations and service deployments.

针对城域网采用开源软件商业模式的光网络分解技术经济研究

这项工作提供了城域网环境中光分解架构的技术经济评估。该研究将两种光分解选项（部分与全部）与传统基准进行比较，其中光设备受供应商锁定的影响，因为它已部署在当今大多数网络中。我们表明，软件定义网络生态系统中新兴的开源软件项目可以为大中型网络运营商带来显着的成本节约，同时它们可以为网络运营和服务部署带来额外的灵活性和敏捷性。
