File Location Management in Federated Computing Environments
نویسندگان
چکیده
The major objective of the Service Oriented Computing Environment (SORCER) is to form dynamic federations of network services that provide shared data, applications, and tools on a service grid along with exertion-oriented programming. To meet the requirements of these services in terms of data sharing and managing in the form of data files, a corresponding federated file system was developed. The file system fits the SORCER philosophy of interactive exertion-oriented programming, where users create service-oriented programs and can access data files in the same way they use their local file system. The federated file system provides data redundancy in the form of file replication. However, there is no efficient management of these file replicas after creation and the location to which they are replicated to is not taken into account. Thus, a separate File Location Management Framework was developed to fit with the SORCER metacomputing philosophy and to manage autonomically file replication.

Peer-to-peer applications (P2P) are no longer limited to home users, and start being accepted in academic and corporate environments. While file sharing and instant messaging applications are the most traditional examples, they are no longer the only ones benefiting from the potential advantages of P2P networks. For example, network file storage, data transmission, distributed computing, and co...
