Network Performance and Management-Complexity Evaluation of Software-Defined Access Network in Multi-Tenancy Scenario

Abstract

Industrial revolution has transformed social life. Because of the digital disruption, companies reorganize and change their business model to face the challenges of industrial revolution 4.0. The multi-tenant architecture separates each tenant logically while they are physically integrated. This model has a problem in the management of network devices. The difficulty of changing and rigidity of the underlying infrastructure presents few possibilities for innovation or improvement since network devices have generally been vendor locked. A Software-Defined Access Network (SDAN) is a software-defined network that is implemented on an access network. SDAN aims to simplify complicated access management and improve service provision. This paper aims to analyze and evaluate SDAN design performance and complexity management of network devices. Evaluation is carried out by conducting a comparative survey between SDAN and non-SDAN in terms of performance and use case scenarios. Based on the results, it can be concluded that the SDAN has 10%-20% better performance in terms of elapsed times and throughput. It also significantly reduces time for managing network devices ten times faster than non-SDAN.
