A Service Migration Strategy for Resilient Multi-Domain Networks in Outage Scenarios

Abstract

Network slicing has emerged as a crucial technology in 5G and post-5G networks, enabling the creation of customized logical networks on a shared physical infrastructure. However, the problem of service placement, which entails determining the optimal deployment of network functions within each slice, becomes particularly challenging during outage scenarios. Service migration serves as a critical technique for reconfiguring and relocating network functions, thereby ensuring the resilience and availability of the slices. This paper presents a service migration strategy specifically designed for resilient multi-orchestrator multi-domain networks. Our approach considers multidomain services composed of components deployed across different network domains using Kubernetes clusters. The abstract nature of this migration strategy allows for its adaptation to different orchestrators within a cluster, facilitating the integration of more diverse and heterogeneous systems.
