An architecture to support multi-node downloading of distributed virtual environment on grid.

Abstract

We propose a three-layer framework and a Globus-based architecture of grid-enabled multi-node downloading mechanism to facilitate a flexible and scalable downloading large scale distributed virtual environments. In our proposed architecture, each grid node is regarded as a potential downloading service provider when available. The performance of downloading DVE is proportional to the number of grid nodes participated in the downloading task. A specific component, multi-node downloading (MND) is devised for supporting remote multi-thread downloading DVE based on Globus platform. MND consists in a multi-node downloading protocol and an adaptive multi-node downloading balancing (AMDB) algorithm. MND is deploying onto our developing "Virtual Zhuhai Campus of Jilin University". Initial experimental results show the feasibility and effectiveness of our approach.
