A replica location prototype based on hiberarchy and full-index structure

After thorough exploration of the replica management component in globus toolkit4,a replica location prototype based on hiberarchy full-index is designed.A system framework,replica location principle,soft-state update and replica location algorithm are proposed,and the replica location prototype is implemented.By means of deployment and running the prototype system,the algorithm is verified.The result shows that this prototype system is able to achieve replica location and create replicas safely and efficiently.
