✦ Synopsis
Virtual execution environment control (VEEC) has been proposed to improve the response time of remote knowledge-base access using the satellite communications. In VEEC, the knowledge base is divided into independently executable knowledge-base subsets called sources, and their transmission between server and client computers are controlled by the source search graph, which represents the execution orders between sources by a directed graph. In this article, source prefetch strategies for improving VEEC performance are proposed, and their effectiveness is assessed by experiments using the JCSAT satellite. A WWW virtual access system is proposed as a new VEEC version for the WWW computational environment. New page prefetch strategies are proposed and experimentally assessed using the JCSAT satellite.
