The Trickle - Down E ect : Web Caching and Server Request Distribution

Web proxies and Content Delivery Networks (CDNs) are widely used to accelerate Web content delivery and to conserve Internet bandwidth. These caching agents are highly e ective for static content, which is an important component of all Web-based services. This paper explores the e ect of ubiquitous Web caching on the request patterns seen by other components of an end-to-end content delivery ar...

The Trickle-Down Effect: Web Caching and Server Request Distribution

Usability of ECT for Quantitative and Qualitative Characterization of Trickle-Bed Flow Dynamics Experiencing Filtration Conditions

This work investigates the pros and cons of using the Electrical Capacitance Tomography (ECT) for imaging and quantitative characterization of flow dynamics in a four-phase trickle-bed reactor. ECT use is increasing in non-invasive imaging thanks to its low cost and convenience compared to nuclear ionizing, non-ionizing and other tomography methods. Yet, ECT has low spatial resolution, lack of ...

Cost-Aware WWW Proxy Caching Algorithms

Web caches can not only reduce network tra c and downloading latency, but can also a ect the distribution of web tra c over the network through costaware caching. This paper introduces GreedyDualSize, which incorporates locality with cost and size concerns in a simple and non-parameterized fashion for high performance. Trace-driven simulations show that with the appropriate cost de nition, Gree...
