My main research interest is algorithms and mechanisms for making routing more resilient. I am affiliated with the NetSys group, as the leader of the Resilient Networks project. The aim of this project is to develop solutions that increase the resilience of networks.
Recently, I have a particular interest in measuring and understanding the reliability of mobile broadband connections. For more on this, see our e-vote project page, and a visualization of some of our measurements on the NEVADA pages.
I am also working actively on
- Mechanisms for fast recovery from link and node failures in IP networks (see our papers at INFOCOM 2006, INFOCOM 2007, INFOCOM 2009, IEEE/ACM ToN and IEEE ToNSM)
- More robust (intradomain) routing, which can perform well even in the presence of failures or unexpected traffic patterns (see our paper at ICNP 2009)
- Scalability issues in BGP interdomain routing, with an emphasis on the evolution of churn (see our paper at CoNEXT 2008, INFOCOM 2010 and IEEE JSAC)
Previously, I have worked on resilience, fairness and bridging issues in the new IEEE 802.17 Resilient Packet Ring standard. Click on the link above for a complete list of publications.
From September 2007 to July 2008 I was a visiting researcher at the College of Computing at Georgia Tech in Atlanta, USA. My main collaborator at Georgia Tech is Constantine Dovrolis.
I am also managing director of Resiliens A/S , a startup based on our work in the area of fast recovery mechanisms.
