Hubbedness: a Metric to Describe Traffic Flows in Optical Networks and an Analysis of its Impact on Efficiency of Point-to-Multipoint Coherent Transceiver Architectures

Abstract

We propose a new metric called hubbedness to describe traffic flow in modern optical networks. We compare theoretical savings of point-to-multipoint vs point-to-point transceivers and find significant savings for a wide variety of traffic patterns when optical transceivers of sufficiently high data rates are available.
