# Deterministic contention management for low latency Cloud RAN over an optical ring

## TL;DR

This paper explores a deterministic traffic management approach for Cloud RAN over an optical ring, aiming to reduce latency and improve overall network performance in 5G deployments.

## Contribution

It introduces a novel deterministic contention management method tailored for low latency Cloud RAN over optical ring networks.

## Key findings

- Deterministic management reduces Cloud RAN latency
- Improves overall network latency for other traffic
- Compatible with low-cost optical ring technology

## Abstract

The N-GREEN project has for goal to design a low cost optical ring technology with good performances (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.
