Luciano Paschoal Gaspary, Deputy Dean and Associate Professor of the Institute of Informatics, UFRGS (Brazil) delivered a lecture about Network Function Virtualization: Research Challenges and Recent Advances

NFV enables network managers to replace specialized middlebox hardware (performing functions such as firewalling, intrusion detection, load balancing, content caching, etc.) with equivalent, software-based network functions, running on top of commodity, off-the-shelf hardware. It makes possible prompt responding to fluctuations in the aggregated flow traffic through dynamic, on demand (de)allocation/dimensioning of network functions.
