Operation of optical spectrum as a service in disaggregated and multi-operator environments [Invited]
Fiber optical communication networks are the backbone of our interconnected digital environments. Motivated by vendor neutrality and better utilization of the vacant optical spectrum in dense wavelength-division multiplexing (DWDM) networks, the operators are interested in implementing optical spectrum as a service (OSaaS) in their networks. In the OSaaS service model, the DWDM network operator grants the end customer direct access to the spectral resources in the DWDM system, and the transceiver equipment purchase, its operation, and future upgrades are the responsibility of the service end customer. If the spectral resources are available in adjacent network segments and the performance of the individual segment is adequate, OSaaS allows optical signals to be operated over thousands of kilometers, traversing multiple domains. These domains can be owned by different operators and built using different DWDM network technologies, utilizing different components and channel plans. This can pose a threat to the network integrity, as today, no dedicated demarcation points exist to police the received and transmitted signals as per the next domain’s requirements. This paper reviews the readily available equipment to provide demarcation functions between the operator domains and introduces an infrastructure-, DWDM technology-, vendor-, and domain-independent optical demarcation device called the network domain interface device (NeDID). We discuss how NeDID provides signal policing and compatibility monitoring, enabling a new, infrastructure-independent networking concept—a transparent optical overlay network (TOON). We further explain the ownership of the NeDID devices and investigate the techno-economic benefits of operating flexible and secure OSaaS over any underlying optical network infrastructure.
期刊介绍:
The scope of the Journal includes advances in the state-of-the-art of optical networking science, technology, and engineering. Both theoretical contributions (including new techniques, concepts, analyses, and economic studies) and practical contributions (including optical networking experiments, prototypes, and new applications) are encouraged. Subareas of interest include the architecture and design of optical networks, optical network survivability and security, software-defined optical networking, elastic optical networks, data and control plane advances, network management related innovation, and optical access networks. Enabling technologies and their applications are suitable topics only if the results are shown to directly impact optical networking beyond simple point-to-point networks.
