Comparative study of optical interconnection architectures in data center networks

The internet traffic is increasing exponentially with cloud services. This demands high and efficient data center networks (DCNs). Current DCNs are equipped with electronic counter parts which consumes high power to provide the cloud services. Optical interconnection network (OIN) architectures provide high scalability low latency high throughput and low power consumption. This paper presents a study of the OIN architectures as the future requirements of the DCNs are the need for high scalability and low latency. This paper also presents a comparative study of their average latency and scalability. © 2019 Walter de Gruyter GmbH Berlin/Boston 2019.
