Achieving low-latency is paramount for live streaming scenarios, that are now-days
becoming increasingly popular. In this paper, we propose a novel algorithm for bitrate …

Radio Access Network Virtualization (vRAN) will spearhead the quest towards supple radio
stacks that adapt to heterogeneous infrastructure: from energy-constrained platforms …

The advances in virtualization technologies have sparked a growing transition from virtual
machine (VM)-based to container-based infrastructure for cloud computing. From the …

Virtualized base stations (vBS) can be implemented in diverse commodity platforms and are
expected to bring unprecedented operational flexibility and cost efficiency to the next …

We study the problem of in-network execution of data analytic services using multi-grade
VNF chains. The nodes host VNFs offering different and possibly time-varying gains for each …

The increasing large-scale workload trace collected by datacenter monitors has provided
great potential for workload prediction. However, resource usage pattern changes of …

Network slicing markets have the potential to increase significantly the utilization of
virtualized network resources and facilitate the low-cost deployment of over-the-top services …

The benefits of cloud computing have attracted many organizations to migrate their IT
infrastructures into the cloud. In an infrastructure as a service (IaaS) model, the cloud service …

Network slicing has been proposed as a paradigm for 5G+ networks. The operators slice
physical resources from the edge, all the way to datacenter, and are responsible to …

In this paper, we study an optimal online resource reservation problem in a simple
communication network. The network is composed of two compute nodes linked by a local …
