“The hourglass (or bow-tie) effect in evolving hierarchical networks”
Speaker: Constantine Dovrolis, Professor at the College of Computing of the Georgia Institute of Technology
Several natural and technological systems and processes can be modeled as hourglass-like hierarchical networks. This is true for biological development, metabolism, the structure of the Internet’s protocol stack and the call-graph in Linux. This talk will investigate the reasons behind this pattern and what it means for the function and evolution of the corresponding systems.
This was a presentation of the YINS Distinguished Lecturer Series on April 1, 2015.
Dr. Dovrolis’s research interests include internet economics, understanding the evolution of the internet ecosystem, measurement tools for the detection of network neutrality violations, the scalability of inter-domain internet routing, and network science methods and applications.
