Application-Oriented Optical Transmission Control for Computationally Efficient Edge Computing

Abstract

Network requirements in optical access networks continue to expand, and softwarization of transmission function has been studied for complete virtualization of access systems. In order to meet the requirements posed by Internet of Things (IoT) applications, SDN/NFV-based access network is an excellent candidate for the edge computing platform needed. However, using a common transmission method is inefficient and will increase the computational loads placed on edge servers. We are aiming to maximize the benefits of SDN/NFV by realizing transmission that can respond to individual IoT application requests. This paper proposes novel application-oriented optical transmission control to enhance computational efficiency, especially for image processing applications. Our proposal is implemented on a general-purpose server and we demonstrate its performance on a 10-Gbps optical transmission system. The results show that the proposal does achieve transmission control to suit application requests.
