A Linux-based Virtualized Solution Providing Quality of Service to SDN-NFV Telecommunication Applications

Currently, Software Defined Networking (SDN) and Network Function Virtualization (NFV) are gaining growing interest due to the increased flexibility they could bring in the design of modern telecommunication systems. The nature of SDN-NFV allows a wide range of applications to run concurrently on the same hardware resources that can be managed by virtualization technologies. However, these applications present heterogeneous requirements in terms of resource demand and timing constraints. Thus, it is necessary to recognize different classes of virtualized applications and to provide specific service guarantees for each of them.
In this paper, we define a reference model characterizing SDN-NFV virtualized applications. We then exploit resource reservation capabilities provided by SCHED_DEADLINE, combined with Direct Interrupt Delivery and Completion, in order to provide specific service guarantees for each of these models. Finally, we conclude with an experimental evaluation which shows the effectiveness of our approach.
