Deterministic Contention Management for Low Latency Cloud RAN over an Optical Ring

Abstract

The N-GREEN project has for goal the design of a low cost optical ring technology with good performance (throughput, latency) without using expensive end-to-end connections. We study the compatibility of such a technology with the development of the Cloud RAN, a latency critical application which is a major aspect of 5G deployment. We show that deterministically managing Cloud RAN traffic minimizes its latency while also improving the latency of the other traffics.
