Scalable deterministic scheduling for WDM slot switching Xhaul with zero-jitter

Abstract

Abstract-A low-cost WDM slot switching "N-GREEN" network is studied for the Xhaul application. We assess the impact of inter-slot intervals on the jitter in N-GREEN and propose a deterministic scheduler ensuring a zero-jitter performance as needed by CPRI traffic. We also propose an integer linear program and a corresponding scalable heuristic and use these tools to evaluate the efficiency of the new scheduler within the N-GREEN technology. The results show important savings and improvements in cost, energy consumption, latency and jitter using N-GREEN w.r.t. state-of-the-art Ethernet Xhaul.

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

“…In this article, we study a Cloud RAN (C-RAN) application based on the N-GREEN optical ring described in [7], [16]. C-RAN is one of the major area of development for 5G; it consists in centralizing or partially centralizing the computation units or BaseBand Units (BBU) of the Remote Radio Heads (RRH) in one datacenter [11].…”
