The GT Noise group is actively working in the following four areas:
- Fixed and mobile broadband access networks. Fixed and mobile broadband access is proliferating in countries around the world. Thus, it is increasingly important to develop methods for measuring the performance of these networks. We have developed a platform called BISmark that runs on routers in home networks and performs passive active measurements of network performance. We are collaborating with the Federal Communications Commission to develop technologies to better understand access network performance in the United States, as well was with ResearchICTAfrica and other regulatory agencies in Africa and the developing world to understand fixed and mobile broadband performance in developing countries.
- Software defined networking. A recent trend in computer networking is software defined networking (SDN), which separates the network’s control plane (the logic that defined forwarding behavior) from the data plane (the devices and technology that forward network traffic). We are involved in developing richer control models for software defined networking to support both dynamic events and middleboxes, as well as exploring various use cases of SDN in both the wide area and in home networks.
- Resonance: Event-based SDN control. (external project page) (github)
- Slick: Middlebox orchestration using SDN.
- uCap: Usage and resource management for home networks (external project page) (github)
- SDX: An Internet exchange point based on SDN control (github)
This recent talk (September 2013) summarizes many of these projects.
- Network security. Our research group tackles a variety of problems related to network security. In 2005, we were developed the first network-level spam filtering algorithms. Since that initial work, we have continued work on a variety of network security projects related to spams, scams, and message abuse. More recently, we have been studying information manipulation attacks and user privacy on the Web.
- Bobble: A Web plugin that exposes inconsistencies in Web search. (external project page)
- Appu: A Web browser plugin that tracks your online privacy footprint. (external project page) (github)
- Spam and scams: Detecting and preventing against abuses of Internet infrastructure and messaging (e.g., spam filtering, Twitter abuse, malicious domain registration)
- Anti-censorship. We are developing methods to provide users information about technologies that obstruct, restrict, or tamper with their access to information. Internet users need an objective, independent, third-party service that helps them determine whether their Internet service provider or government is restricting access to content, specific protocols, or otherwise degrading service. Towards this goal, we are (1) monitoring attempts to block or manipulate Internet content and communications; and (2) evaluating various censorship circumvention mechanisms in real-world deployments.
The video below provides a short (3-minute) summary of some of the research going on in our lab.
