Network function virtualization (NFV) has recently allowed the rapid deployment of network functions. As software implementations become the main option for NFV, performance requirements call for an increased level of hardware support and acceleration. Additionally, the higher demand for flexibility and optimization also requires protocol stack customization at different layers. To fulfill these requirements,...
The upcoming 5G architecture is expected to heavily rely on network functions implemented by software deployed on commodity hardware architectures. Multiple standardization efforts are underway to specify interfaces between virtualized and real infrastructure, and procedures for interoperability among functions. However, the practical feasibility of function implementation in such abstract and disembodied...
We consider a novel way by which DL dynamic MAC scheduling can be augmented based on cross-layer inputs to provide desired performance enhancements. We describe ODDS, an automated design process for the data-driven refinement of downlink resource scheduling algorithms. ODDS extracts insights from the behavior of a simulated LTE cellular system under randomized traffic patterns and propagation conditions...
Datacenters provide an interesting environment for the deployment of information-centric networking (ICN) protocols. The innovative features of ICNs, such as network-layer caching of named data, when combined with new opportunities given by naming semantics, such as the selective forwarding of data processing queries and the on-path processing of partial replies, introduce a large degree of freedom...
The study of human activity patterns traditionally relies on the continuous tracking of user location. We approach the problem of activity pattern discovery from a new perspective which is rapidly gaining attention. Instead of actively sampling increasing volumes of sensor data, we explore the participatory sensing potential of multiple mobile social networks, on which users often disclose information...
DMME is a distributed architecture that implements mobility management for next‐generation cellular systems. It has been designed to serve as a scalable and cost‐effective drop‐in replacement for the Long Term Evolution (LTE) mobility management entity (MME). DMME is an example of a flexible control plane architecture that can be deployed incrementally across operator networks: processing locality...

With the convergence between phone and data networks in LTE and 4G, cellular signaling traffic is increasingly carried over IP. Control plane functions, once performed by dedicated machinery, are evolving into large-scale network applications with strict requirements on delay, availability, and processing throughput as mandated by 3GPP standards. In this paper we present dMME, a distributed architecture...
In this position paper we introduce Virtual Telco, a comprehensive effort to simplify the management of deployed telecommunication services by using a Cloud computing approach. The main objective of Virtual Telco is to replace the costly dedicated hardware implementing several centralized control plane functions and other services with distributed solutions that may be allocated on-demand over a pool...
