Abstract

We present an object-level scalable web framework and discuss our implementation as well as simulation experiences with them. This object-level scalable web framework automatically monitors access patterns, replicates, and maintains large multimedia objects among a set of geographically distributed web servers without the need for full URL replication. This framework employs traceable RTSP/HTTP redirection approach to avoid cyclic redirections among the (geographically distributed) web servers.We implemented this web framework on a wide area network with a set of three web servers: one at the Technical University of Darmstadt (Germany), second one at the Virginia Polytechnic University (USA), and the third at the National University of Singapore. We also carried out a series of simulation experiments to analyze the scalability of this object-level scalable web framework. In this paper, we share these implementation and simulation experimental results.
