Scalable Deterministic Scheduling for WDM Slot Switching Xhaul with Zero-Jitter

A low-cost WDM slot switching "N-GREEN" network running a deterministic scheduling provides zero-jitter forwarding as needed by CPRI traffic. For a first time, a dedicated integer linear program and a corresponding scalable heuristic have been used together to compute such scheduling and evaluate its efficiency with N-GREEN technology. The results suggest important savings and improvements in cost, energy consumption, latency and jitter w.r.t. state-of-the-art Ethernet Xhaul.
