How to guarantee user's QoS (Quality of Service) demands becomes increasingly iportant in service-oriented grid environment. Current research on grid resource advance reservation, a well-known and effective me-chanism to guarantee QoS, fails to adapt to dynamic variability of grid resource, and imprecise deny of user's reservation request often happens. For this, new system architecture for advance reservation is proposed. SNAP (Service Negotiation and Acquisition Protocol) is extended to support this architecture. Then VRC (virtual resource container) is adopted to alleviate negative effect resulted from resource performance variability, and QDD (QoS deviation distance) based logical resource selection algorithm is addressed to decrease imprecise reject rate of reservation. At last, this new architecture is deployed to campus grid, and two illustrative experiments are conducted in campus grid too. Preliminary results show that it can alleviate negative influence of grid resource dynamic fluctuation and avoid imprecise reject of advance reservation request effectively.Full Text at Springer, may require registration or fee
