OLT virtualization in 5G networks

Abstract

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.
