Hands‐on Interdomain network slicing framework and evaluation

Abstract

5G enables tailoring network services to the needs of different vertical use cases. These Verticals may require deployments across distinct communication service providers' administrative domains. Ensuring secure interaction between domains is fundamental for deploying end-to-end services in such environments. This paper examines using Moving Target Defense (MTD) mechanisms to secure VXLAN-based tunneled connections to realize inter-domain deployments. The inter-domain mechanisms are evaluated in different scenarios, mainly targeting throughput and latency, showing the suitability for inter-domain communications even when under load. The assessment of the MTD mechanism ′ s effectiveness considers the number of false positives and negatives associated with its operations.
