Oriented Overlays For Clustering Client Requests To Data-Centric Network Services

Many of the data-centric network services deployed today hold massive volumes of data at their origin websites, and access the data to dynamically generate responses to user requests. The dynamic responses are poorly supported by traditional caching infrastructures, resulting in poor service performance and scalability. One way of remedying this situation is to develop alternate caching infrastructures, which dynamically detect the often large degree of usage locality seen by such services, and leverage such information to redirect requests to service portions replicated on-demand at appropriate network locations. Key to build such infrastructures is the ability to cluster and inspect client requests at various points across a wide-area network. This paper presents a zone-based scheme for constructing oriented overlays, which provide such an ability. Oriented overlays differ from previously proposed unstructured overlays in supporting network traffic flows from many sources towards ...
