Abstract:
Upcoming 5G mobile networks strongly rely on Software-Defined Networking and Network Function Virtualization that allow exploiting the flexibility in resource allocation provided by the underlying virtualized infrastructures. These paradigms often employ platform abstractions designed for cloud applications which have not to deal with the stringent timing constraints characterizing virtualized network functions. On the other hand, various techniques exist to provide advanced, predictable scheduling of multiple run-time environments, e.g., containers, within virtualized hosts. In order to let high-level resource management layers take advantage of these techniques, this paper proposes to extend network service descriptors and the Virtualization Infrastructure Manager. This enables Network Function Virtualization orchestrators to deploy components exploiting real-time processor scheduling at the hypervisor or host OS level, for enhanced stability of the provided performance.
