At my current position at ETH Zurich I work in a great team of researchers on modelling the behaviour of data centres. The general problem is how to formally represent the data traffic flowing through the data centre and its processing such that to predict potential bottlenecks or point of failures. Among the main challenges are coping with the great ammount of data and its high generation speed, uncomplete and inreliable monitoring data and high complexity between the nteraction between the data centre applications, generating that data.
In my previous work on network virtualization part of the project team worked on control of the network via software defined networking (SDN). Their work interested me and I started looking into what SDN is and promisses for networks. Eventually, with fellow researchers, I started working on how SDN can be applied into data centres to introduce application specific knowledge into the control decisions taken during traffic management in a data centre. I also prepared a seminar on SDN in the Spring semester of the 2014/2015 lectures period.
In the scope of the FP7 EU Mobile Cloud Networking (MCN) project I worked on virtualization of the radio part of a mobile LTE network. The researched focused on establishing which parts of the radio signnal processing taking place at the base station can be virtualized and how the vistualization affects the performance of the network. Theoretical models and emulation environment (Open Air Interface by Eurecom) were used.
