SRM-based multi-protocol supported storage

An SRM-based multi-protocol supported storage (MPSS) is proposed to solve the data share problem in a grid workflow environment of cross-domain. The MPSS utilizes managed URL to distinguish different data types, insulate users' private space through mapping different users' space to different physical position, and coordinate different transfer services by controlling authorization of read/write tokens. With these strategies the MPSS implements the data sharing of cross-domain transparently, simplifies the grid workflow's running and improves the efficiency of grid data sharing. The MPSS supports popular transfer protocols, provides a powerful supporting for grid workflow of cross-domain, and shows a good stability and efficiency in practical projects such as aviation, DD grid and meteorology. The results of pressure test show that the MPSS can process at least 300 requests per second with an average response time 1.7 s.
