Abstract
Web servers providing live coverage of events are hard to design due to a high degree of variation in the load, variation in geographical distribution of users and the frequency with which content is updated. In this paper, we propose domain caching , a technique that dynamically distributes the load on the server by instructing selected clients (do- main caches) to cache server content and service requests from nearby clients. We evaluate domain caching using a trace driven simulation study of the 1998 Worldcup Soccer logs. Our simulations indicate that domain caching reduces load on the server by as much as 38% while using a few hundred kilobytes of storage at domain caches. The traces also reveal situations where using domain caching instead of content mirroring reduces network traffic from the server. We built a prototype domain cache to demonstrate the feasibility of some of our ideas. Using this prototype, we show that accessing content from a nearby domain cache is faster than...
