Abstract
Thanks to network slicing, 5G networks will support
a variety of services in a flexible and swift manner. In this context,
we seek to make high-quality, joint optimal decisions concerning
the placement of VNFs across the physical hosts for realizing the
services, and the allocation of CPU resources in VNFs sharing
a host. To this end, we present a queuing-based system model,
accounting for all the entities involved in 5G networks. Then,
we propose a fast and efficient solution strategy yielding nearoptimal
decisions.We evaluate our approach in multiple scenarios
that well represent real-world services, and find it to consistently
outperform state-of-the-art alternatives and closely match the
optimum.
