Investigation of Uninterrupted Service Live Migration Using Software-Defined Networking

The vision of Industry 4.0 is to enable a highly dynamic and flexible manufacturing system. Nevertheless, an uninterrupted and reliable service needs to be ensured to fulfill the safety requirements of the industrial applications. The latest advancements in technologies such as wireless connectivity, hardware virtualization, application offloading, etc. aims to cater to most of these requirements. Moreover, a new paradigm called Edge Computing is becoming a preferred solution to fulfil the latency and availability requirements of the Industry 4.0 applications. However, the dynamic resource management and automated service provisioning remains to be an open challenge in an environment with constantly varying requirements. Service migration is a part of dynamic resource management that enables repositioning of a service from one computation entity, which is e.g., overloaded and cannot satisfy the user requirements, to another computation entity. An uninterrupted service live migration is necessary to satisfy the low latency and high availability requirements of mobile devices on the factory floor. In this paper we introduce and investigate a new approach for an uninterrupted service live migration.
