  • 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.
