Bio

Since November 2016, Rodolfo Alvizu is Postdoctoral research fellow at the Department of Electronics, Information and Bioengineering in Politecnico di Milano, Italy.

He received the B.Sc. degree in Telecommunications Engineering in October 2008 from Universidad Experimental de la fuerza Armada Nacional (UNEFA) in Maracay (Venezuela), discussing a thesis entitled "Assessment of Resource Allocation mechanisms to provide Quality of Service in Optical Burst Switching Networks" under supervision of Prof. Mónica Karel Huerta (Simon Bolivar University).

In October 2011 he obtained the M.Sc. degree in Electronics Engineering from Simon Bolivar University in Caracas (Venezuela) with the thesis entitled "Performance assessment of metro-access network interfacing nodes", supervised by Prof. Mónica Karel Huerta (Simon Bolivar University) and Prof. Idelfonso Tafur Monroy (Technical University of Denmark).

During his master studies Rodolfo did a 6 month research period in the Department of Photonics Engineering, form the Technical University of Denmark (DTU), in Kgs. Lyngby, Denmark.

From January 2012 he became assistant professor of Electronics and Circuits Department from Simon Bolivar University in Caracas (Venezuela), where he is member of the Group of Applied Networks and Telematic (GRETA).

In November 2013 Rodolfo started the Ph.D program in Information technologies (in the Telecommunication area) at the Politecnico di Milano in Milan (Italy), where he become part of the Broadband Optical Networks, Security, and Advanced Internet (BONSAI) Group, under the supervision of Prof. Guido Maier.

His current research interests are related to software/defined networking (SDN), network orchestration, optical networks, multipath routing, and time-aware dynamic network operations.

Toghether with Prof Guido Maier and Prof. Achille Pattavina Rodolfo founded in 2016 SWAN networks, an StartUp commited to the development of a network orchestrator for automation and optimization of enterprise networking

Advanced Control-Plane Techniques in the Software Defined Era for Transport Optical Networks

Advisor: Prof. Guido Maier

Abstract:

Paradoxically, with an ever-increasing traffic demand, today transport-network operators experience a progressive erosion of their margins. The operational complexity, manual configuration and static nature of current technologies lead to: inefficient network utilization, over-provisioning of resources and very high Capital expenditures (CapEx) and Operational expenses (OpEx).

The alarms of change are set, and Software Define Networking (SDN) is coming to the rescue with the promise of reducing CapEx and OpEx. Driven by economic needs and network innovation facilities, today transport SDN (T-SDN) is a reality. It gained big momentum in the last years, however in the networking industry, the transport network will be perhaps the last segment to embrace SDN, mainly due to the heterogeneous nature and complexity of the optical equipment composing it.

Throughout my PhD research work, special focus was given to the transport optical network, that nowadays still provides static connections, but must evolve to provide dynamic pipes between devices and cloud. A paradigm shift that allows such evolution is given by Software Define Networking (SDN). SDN is buzzing the networking world with the promise of programmability and innovation to deploy a new breed of advanced networking applications and techniques.

This work was three-folded into: 1) comprehensive survey of the efforts done by academia, standardization bodies and vendors to enable SDN in transport networks (T-SDN) and deep analysis of this new technology, 2) proposal of advanced optical routing techniques that assume the deployment of SDN technologies, and 3) implementation of SDN use cases using state-of-the-art open source frameworks (MPTCP testbed tool and multi-domain SDN Orchestration).
