Using Overlay Networks to Resist Denial-of-Service Attacks

Proxy-network based overlays have been proposed to protect Internet applications against Denial-of-Service (DoS) attacks by hiding an application’s location. We develop a formal framework which models attacks, defensive mechanisms, and proxy networks. We use the framework to analyze the general effectiveness of proxy network schemes to protect applications. Using our formal model, we analytical...

Overlay Caching Scheme for Overlay Networks

Recent years have seen a tremendous growth of interests in streaming continuous media such as video data over the Internet. This would create an enormous increase in the demand on various server and networking resources. To minimize service delays and to reduce loads placed on these resources, we propose an Overlay Caching Scheme (OCS) for overlay networks. OCS utilizes virtual cache structures...

Path Optimization in Stream-Based Overlay Networks

The emergence of sensor networks and distributed applications that generate data streams has created a need for Internet overlays designed for streaming data. Such stream-based overlay network (SBONs) consist of a set of Internet hosts that collect, process, and deliver stream-based data to multiple applications. A key challenge in the design and implementation of SBONs is efficient path optimi...
