Research Interests

In 2008, I joined the Design, modelling and evaluation of broadband networks group (BAMPLA) in the Telematics Engineering Department of the technical university of Catalonia. The research of BAMPLA focuses in the field of Internet Architectures, service and traffic modelling and network measurements. At present the group has more fifteen members. BAMPLA is currently involved in several national and international research projects, such as: Euro-NGI, Euro-NF, All4Green and Mantychore.

In July 2013, I joined the group on applied telecommunications (GITA) at the Engineering Faculty of the University of Antioquia.

Currently, I'm working in several fields: Resource allocation in Network Virtualization, Green Service Level Agreement (GreenSLA) and software defined networking.

Resource Allocation in Network Virtualization

Particularly, as my main thesis topic, I've been working on the well known Virtual Network Embedding (VNE) problem. This problem deal with the efficient allocation of virtual network demands on top of the resources of the physical networks. This optimality can be calculated with regard to different objectives: Cost minimization, resiliency provision or energy saving. I have worked developing algorithms and models to solve the cost-based and energy efficient VNE. Also, I have started to work in the resource allocation problem in Network Functions Virtualization, called NFV-RA.

Green SLAs

In September 2011, the european FP7 ALL4GREEN project started. BAMPLA is one of the partners of the project. ALL4GREEN looks for the collaboration of the different actors involved to run a Internet application to save energy and reduce the CO2 emissions. These actors are: IT customer, datacenters and energy providers. My current work inside ALL4GREEN is to define Green Service Level Agreements (GreenSLAs) that allow datacenters to provide flexible contracts to the IT customer, so that it can behave in a more environmental friendly way.

Software Defined Networking

Currently, Software Defined Networking (SDN) has received great attention from both, industry and academy. it mainly consists on making the network programmable by separating the control plane from the data plane. Many applications can be then freely developed for the networks from third parties. Currently, I'm working on SDN applied to smart grid, the aim is to control the data network of the electrical grid in a smart way to reduce costs and offer better services with guaranteed quality.
