Research Interests
With the rapid technology advancement in wireless sensors, handheld
devices, and smart appliances, the future network infrastructure has
to be flexible enough to connect these heterogeneous end nodes over
different access technologies, from traditional wireline networks to
the wireless counterparts (including highly mobile networks). The key
design requirement is to achieve robustness and high performance in
the face of failures, malicious attacks, time-varying load, and
heterogeneous application requirements.
The research efforts of the RUBINET Group focus on designing network
infrastructures, protocols, and techniques that support robust,
secure, efficient, and ubiquitous (mobile) computing. Our approach is
driven by analysis of real Internet traffic and network measurements.
As the Internet becomes an essential part of our everyday life, it has
grown to a complex distributed networked system that is hard to
characterize. Our group is also interested in developing foundations
for measuring and validating the system behavior and end-to-end
properties of the Internet. For example, how does one measure,
predict, or validate end-to-end reachability or security property
between two points in the network? We also seek to model the
interactions between different entities as well as across multiple
protocol layers/modules.
The following are on-going projects of RUBINET:
- RoSE: Robust, Secure & Efficient
Routing
The main objective of this project is to improve the
fail-over time and increase the service availability of Internet
routing infrastructure while maintaining its stability. This requires
a thorough understanding of the failure characteristics and behavior
of currently deployed, large-scale, operational wide-area IP network.
This work is carried out in collaboration with the IPMON Project at Sprint Advanced Technology Labs
(ATL). Based on real network measurements, we will develop a
"service availability" model that captures the failure characteristics
of the current Internet.
- SaND: Sampling the Internet for Effective
Network Anomaly Detection
Our ultimate goal is design
accurage, versatile, and light-weight traffic measurement techniques
that can cope with high-link speed while accurately tracking traffic
features that are critical for various network management or security
defense tasks. We start by investigating if existing sampling
techniques manage to capture sufficient traffic footprints for
effective anomaly detection.
- CPR: Cooperative
Packet Repair
This project explores the idea of recovering
wireless broadcast (e.g., through cellular networks) losses using the
peer-to-peer ad-hoc wireless connections (e.g., through WLANs or
bluetooth).
