Dear colleagues,
You are cordially invited to attend, TODAY, at the IT AMPHITHEATER at 18h, the invited talk by Dr. Artur Hecker on "TOWARDS AN SDN-BASED MCN".
In this talk, we compare different ways, how today's highly popular OpenFlow SDN (concept, principles, technologies) can be used in the telco networks. By juxtaposing the telco requirements and the SDN reality, we reveal several interesting findings about what SDN is and what it probably should be, hence identifying gaps for further SDN-related research. Then, assuming most of the identified problems are solved, we compare different ways how SDN could be employed in the core network realization of a mobile operator. Here, we start with an almost standard-conform "SDN as an interface to the data plane" and then progressively add NFV into the picture, get rid of tunnels, dissolve or remove some architectural entities, until we converge at a quite radical FULL-SDN redesign of the current MCN. During this walk along the design  space, we briefly introduce every idea trying to gather its pros and cons, when necessary by referring to the relevant state of the art at the origin of the respective ideas.
Finally, we are trying to justify the proposed Full-SDN approach for MCN design by looking at the promises of what today is generally referred to as 5G. We first discuss the architectural and operational advantages of the Full-SDN design. Then, we present our prototype implementations of some MCN functions and, by delving deeper into the implementations, show some more specific problems and bottlenecks in the SDN switches and the SDN controllers. Here, we intend to show some early, still unpublished, quantitative results as a motivation for further studies.This talk mostly presents new, partly unverified ideas, and is therefore thought as a motivation for further research for Master- and PhD-level students. We hope to convey an idea about the current state of the 5G research, debunk some often-repeated myths about the SDN, confirm some fundamental truths about distributed systems but also show the promising potential of general abstractions and functional decoupling.

Dr. Artur Hecker (MSc from Universität Karlsruhe and PhD from the ENST, Paris) is Director of Future Networks Technologies at the European Research Center of Huawei Technologies. From 2006 to 2013, Artur was Associate Professor at Télécom ParisTech, where he was leader of Security and Networking group. Artur looks back at more than 15 years of entrepreneurial, academic and industry experience in networks, systems and system security research.

The first step for further enhancing wireless mobility experiments at the AMazING testbed was taken with a try out of a first version of a new mobile device.
   

This device, which will be able to carry a computing and networking node, will be able to run on a rail at the rooftop of the Instituto de Telecomunicações. In this way, it becomes possible to realize very precise wireless and mobile experiments, at different speeds. 
 Check a first sneak peek here!.

This semester, two new students will initiate their Master Thesis work on 5G networks, in our group. 

Pedro Bispo will assess the contributions and performance of Software Defined Networking mechanisms in mobility scenarios in wireless environments.

Ricardo Braga will explore the outcomes of current 5G research directions and their contribution advanced utilisation scenarios.

Both thesis' aim to contribute towards the on-going international 5G research effort, providing new visions and possibilities in novel scenarios. Both students are being supervised by Daniel Corujo and Rui Aguiar.
