ReDCN: A Dynamic Bandwidth Enabled Optical Reconfigurable Data Center Network

Abstract

A reconfigurable optical data center network is proposed, in which the optical bandwidth can be automatically reconfigured by reallocating time slots based on the real time traffic. Numerical investigations validate that the network performance of packet loss after reconfiguration decreases by 58.5%, and the end-to-end latency decreases by 63.8% with comparison to the network with rigid link interconnections, and thereby increasing the 9.4% of throughput at load of 0.8.
