Abstract

Limited by computing resource, network resource and today's technologies, the scalability of collaborative virtual environment(CVE)has not been efficiently solved until now. The paper discusses the communication model of large-scale CVE first and then devises a CVE architecture based on open grid services architecture(OGSA). Utilizing grid service the CVE architecture separates CVE function realizations from physical resource to solve the scalability of CVE. In addition, the paper focuses on the research of virtual world management service and some related services such as interest management service, consistency management service and concurrent management service which are key issues to solve the scalability of CVE. At last, a CVE case based on Globus Toolkit is developed to validate the feasibility of the proposed CVE architecture and methods.
