This paper describes the OLT virtualization technology in 5G networks. New services, the rapid development of Internet of Things technology and next generation mobile 5G networks are leading to a huge increase of Internet traffic, which requires higher optical network bandwidth and reliability. This means that future optical transport network and access solutions must provide flexible bandwidth for dynamic services through intelligent management. At the same time, optical networks still face difficulties in service deployment and expansion. The main issue is to ensure guaranteed performance, including routing protocols, convergence and route calculation time, path discovery time, reliability and resource utilization. Current solutions for operating and maintaining optical networks is not aligned with growing customer demands. For these reasons, optical virtualization is a promising technology to meet a given set of network requirements while providing the necessary isolation between network segments. The prospective solution in the field of virtualization on 5G networks is the technology of vOLT. The application of vOLT in 5G networks offers several advantages. This paper presents the concept of OLT virtualization in 5G networks and its application in optical networks and transport and access solutions. The paper describes the implementation of vOLT technology, its advantages and existing problems.

Proceedings Volume 11793, 1179302 (2021) https://doi.org/10.1117/12.2591940

Read Abstract +

This paper describes virtualization in optical networks. The rapid growth of Internet traffic, new services and the rapid development of technologies such as the Internet of Things and next generation 5G mobile networks require greater demands on the bandwidth of optical networks. Variety of network services requires network transport with more flexible bandwidth access capabilities. This means that future transport networks must provide flexible bandwidth for dynamic services through intelligent management. In the same time, optical networks still face certain challenges in introducing and expanding services. The main difficulty is to provide guaranteed performance, including access to routing, convergence and route computation times, path detection time, reliability and resource utilization rate. Current level of operation and maintenance of optical networks does not meet the requirements of customers. For these reasons, optical virtualization is a necessary technology to meet the specified set of network requirements, while providing the necessary isolation between its segments. This document first introduces the concept of optical network virtualization and its application for optical network elements and transport technologies. Then the paper describes the various technologies of virtualization in optical networks and the existing problems.
