Virtual and Dynamic Hierarchical Architecture for E-science Grid

摘要

This paper presents an e-Science Grid architecture called as Virtual and Dynamic Hierarchical Architecture (VDHA). VDHA is a decentralised architecture with some P2P properties. VDHA has scalable, autonomous properties, and full and effective service discovery. The synchronization can be easily achieved by using VDHA. Further more, VDHA has the security architecture fulfilling the requirements of Grid. VDHA was adopted by Chinese University e-Science Grid as its architecture. In this paper, the advantages and several protocols of VDHA are also discussed.
