Securing connectivity during a catastrophe was research subject of new UdeC engineer work

Diego Mendoza Muñoz, member of Optoelectronics Division from Center for Optics and Photonics, CEFOP, from Universidad de Concepción, successfully presented his grade memoir defense exam, obtaining his Civil Engineering in Telecommunications degree, with a 7.0 rate.

IMG_2228“Networks’ topologic analysis facing multiple failures caused by risk groups with shared resources” is the name of his work, which consisted in studying correlated failures in network topologies, caused by risk group links with shared resources, e.g. fiber optic links and other data transmission systems.

The objective of the work was to study real networks to diminish probabilities for links to totally fail. This, through topologic changes in the networks, providing alternative courses at physical or logical level, during an emergency, produced by a natural phenomenon, such as the earthquake registered on February 27th 2010 in Chile.

IMG_2234_Professor Dr. Jorge Pezoa, who performed as research guide, explained the purposes of this study, and scientific motives to choose this subject. “In this case, we were trying to make an analysis on resilience and reliability of a telecommunication network, facing massive failures, such as those caused by catastrophes, optical fibers cuts, hurricanes, tornados and earthquakes. For that, we used shared risks theory, in which failures are produced by practical events. This subject comes from an interest from my Ph.D. degree, in which we made correlated failures model, but always keeping it all too theoretical, and looking forward, we got to know this very practical model, pretty developed in Massachusetts Institute of Technology (MIT, US). Practice application is clear: this provides a basis for generating protections schemes for, e.g., catastrophes. And this is applicable for telephonic and computing networks”, sustained the also Telecommunications Civil Engineering program director.

IMG_2235_By his side, researcher Diego Mendoza highlighted applicative and practical potential of his research results. “It was an intense work we realized along the whole semester and in reference to the impact we can generate in the future, it is something applicable, which satisfies me much more, along with the academic result, in case of natural catastrophes, especially because we are in a very seismic country, so trying to avoid these risk groups and to keep services continuity is very important. Now, I want to work in some company that will allow me get this results to practical use, or settle my own initiative to take theme to practical uses”, said the new UdeC engineer about his professional development plans.
