Abstract

This paper describes a new framework for Grid-enabled advanced DVE (Distributed Virtual Environment) which provides a dynamic execution environment by supporting discovery and configuration of resources, mechanism of security, efficient data management and distribution. While the previous DVEs have provided static execution environment only considering communication functions and efficient application performance, the proposed framework adds resource, security management, extended data management to static execution environment using Grid services, and then brings dynamic execution environment which result in QoS (Quality of Service) enhanced environment better performance.The framework consists of two components: Grid-dependent component and Communication-dependent component. Grid-dependent component includes RM (Resource Manager), SDM (Static Data Manager), DDM (Dynamic Data Manager), SYM (Security Manager). Communication-dependent component is composed of SNM (Session Manager) and OM (Object Manager). The components enhance performance and scalability through the DVEs reconfiguration considering resources, and provides mutual authentication mechanism of both servers and clients for protection of resources, application and user data. Moreover, effective data management reduces overhead and network latency by data transmission and replication.
