Welcome to the Network and Distributed Systems Group (NDS) at Duke's Computer Science department. NDS group's research area includes distributed protocol and architecture design, performance analysis, modeling, and measurement.

• CloudCmp: Compare public cloud providers and estimate the performance and costs of cloud applications.
• FaceTrust: Leverages social networks to assess the credibility of identity statements made by online users.
• SocialFilter: Exploits social networks to build trust among detectors of unwanted traffic. Aims at enabling nodes that cannot detect Internet threats (spam, worms, malware) to reliably exploit the aggregate experiences of nodes that can.
• SafeGuard: consistent yet responsive routing system design and implementation to avoid transient disruption after network change.
• User-Selected Routes: a system approach to enable end-users' control over the routing decisions.
• DDoS Flooding Attack Mitigation: Mitigate Distributed Denial-of-Service (DDoS) flooding attacks using capabilities, source authentication and network filters.
• Dandelion: Robust and efficient incentives for cooperative content distribution using lightweight cryptographic fair exchange.
