CS Colloquia: Network Resilience to Attack and Disaster

Title: Network Resilience to Attack and DisasterSpeaker: Prof. Dan Rubenstein (Columbia)ABSTRACT:
Traditional network design can compensate for a small number of node
and link failures, but cannot handle attacks or failures on a massive
scale. These massive-scale phenomena may be due to malicious behavior
in the network, such as a denial of service attack, or due to
disaster, such as an emergency sensor network deployed in a
catastrophic location such as a fire or flood. A primary focus of our
research has been to design or enhance routing protocols so that they
are more resilient to these massive-scale challenges. The talk will
first cover the Secure Overlay Services (SOS) architecture we proposed
that utilizes network overlays to proactively protect targeted
Internet sites from distributed denial of service (DDoS) attacks.
Next, we will explore the problem of maximizing the amount of data
that can be extracted to a base-station from a sensor network whose
nodes are undergoing rapid failures. We develop a novel distributed
network coding technique and demonstrate how, in a massive failure
setting, our coding/routing technique outperforms prior state-of-the-art. I
will finish the talk with a brief run-through of other projects that
our lab has focused on.BIO:
