Mobility revisited in software defined telecom infrastructures
| Summary: | The 5G networks, and those that follow, are facing an unprecedented increase in mobile data traffic, along with the rising need to support complex, latencyintolerant services. This has prompted telecommunication service providers to seek novel paradigms and techniques to accommodate their customers’ demands and enable novel Quality of Service aware services for mobile users. The Virtualized Edge concept is one of the most promising platforms envisioned as an enabler for delay-sensitive services in future systems. These platforms intend to support latency-aware services by getting resources and computing capabilities closer to the user equipment, placing them on the network edge. Implementing solutions like these brings a new set of challenges. The near-user deployment directly exposes the services to clients’ mobility and to sudden topology changes, making mobility management more challenging, and calling for careful service and resource orchestration to preserve the Service Level Agreement. To facilitate mobility management, novel techniques have been suggested as complementary methods to support mobility and enable latency-intolerant applications alongside the conventional handover procedures. Some of the most relevant techniques includes service instance mobility or migration, optimized low-delay handover, and adaptive and parallel task offloading. In this thesis, we explore different policies and techniques to realize Quality of Service aware services for mobile users, following the paradigm of a virtualized access network. We incorporate these techniques into a orchestration and management layer, adequate to the virtualization of resources in this environment. |
