Network Slice Embedding over Space Division Multiplexed Elastic Optical Networks

2026-04-13

AI Summary

This work addresses the inefficiency of existing network slicing approaches in space-division multiplexed elastic optical networks, which typically decouple spectrum and computing resource allocation and thus struggle to meet dynamic service demands. To overcome this limitation, the paper proposes a Waypoint-assisted Multi-Segment Slice Mapping (WMSM) scheme that, for the first time, jointly optimizes computing resource placement and spectrum allocation in a sequentially coupled manner, unifying routing, modulation format, core, and spectrum assignment (RMCSA) into a cohesive strategy. Experimental results demonstrate that WMSM significantly outperforms state-of-the-art baselines, achieving up to a 27% improvement in slice acceptance ratio under high traffic loads and reducing total deployment costs by as much as 47%, thereby substantially enhancing both resource utilization efficiency and service reliability.

Abstract

Network slicing over space division multiplexed elastic optical networks (SDM EONs) enables efficient multiservice provisioning on a shared optical substrate. However, embedding such slices requires coordinated spectrum and compute resource management under dynamic traffic, which most existing RMCSA studies treat independently. This paper focuses on the network slice embedding problem over space division multiplexed elastic optical networks (SDM EONs), aiming to develop efficient resource allocation strategies that ensure both high utilization and reliable service performance. While prior studies have investigated routing, modulation format, core, and spectrum allocation (RMCSA), they typically consider these dimensions separately from compute placement. To address this gap, this paper proposes a Waypoint Assisted Multi Segment Slice Mapping (WMSM) scheme, which integrates compute placement with spectrum allocation in a sequential but coupled manner to enable more flexible resource placement and improved spectrum efficiency. Numerical results show that WMSM improves acceptance ratios by up to 27% under high load conditions, while achieving up to 47% lower total provisioning cost relative to the baseline strategy. These results highlight the benefits of integrated compute spectrum provisioning and provide design insights for scalable, compute aware optical slice mapping.
