I am currently a fourth year PhD student in Duke university working with Prof.
Xiaowei Yang.
I moved to Duke with my advisor in Fall 2008. Prior to that I spent two years
in
UCIrvine. I
obtained my BS in Electronic Engineering from
Tsinghua University, Beijing.
Research
My research interests include designing, implementing,
and analyzing high performance networked computer
systems. My current research topics include:
- Make
routing systems more robust to failures
and topology changes
- Optimize
routing systems by using multiple
forwarding paths
Projects
- SafeGuard:
SafeGuard is a novel intra-domain routing system which
achieves two goals simultaneously: (1) ensures
consistent forwarding (loop-free) and (2)
responds to network changes quickly. In
SafeGuard each packet carries its path cost as
a "safeguard" information to detect and repair
routing inconsistencies, while routing
converges normally.
- Improving NotVia:
NotVia is an IP Fast Reroute technique aiming
to reduce disruption time after network
failures. We propose several techniques to
reduce NotVia's overhead and make it more
efficient and deployable.
- Adoptability Modelling on Source Authentication Solutions:
Source authentication is a mechanism to prevent
source address spoofing. In this project we
model the adoptability of current source
authentication solutions, and analyze how
likely they can be deployed in reality.
