Adaptive Data Transfers that Utilize Policies for Resource Sharing
High Performance Computing, Networking, Storage and Analysis（2012）
摘要
With scientific data collected at unprecedented volumes and rates, the success of large scientific collaborations requires that they provide distributed data access with improved data access latencies and increased reliability to a large user community. The goal of the ADAPT (Adaptive Data Access and Policy-driven Transfers) project is to develop and deploy a general-purpose data access framework for scientific collaborations that provides fine-grained and adaptive data transfer management and the use of site and VO policies for resource sharing. This paper presents our initial design and implementation of an adaptive data transfer framework. We also present preliminary performance measurements showing that adaptation and policy improve network performance.
