在本文中，我们提出了一种对GridFTP的扩展，它通过动态调整并行TCP连接的数量来优化其性能。在网格计算中，为了有效地传输海量数据，采用了GridFTP作为数据传输协议。GridFTP支持一种称为并行数据传输的功能，该功能通过并行建立多个TCP连接来提高吞吐量。但是，为了获得较高的GridFTP吞吐量，应该根据网络状态来优化TCP连接的数量。本文提出了一种自动调整并行度的机制GridFTP-APT(GridFTP With Automatic Parallism Tuning)，该机制根据网格中间件所能获得的信息来调整并行TCP连接的数量。通过仿真，我们证明了GridFTP-APT在各种网络环境下显著提高了GridFTP的性能。
In this paper, we propose an extension to GridFTP that optimizes its performance by dynamically adjusting the number of parallel TCP connections. GridFTP has been used as a data transfer protocol to effectively transfer a large volume of data in Grid computing. GridFTP supports a feature called parallel data transfer that improves throughput by establishing multiple TCP connections in parallel. However, for achieving high GridFTP throughput, the number of TCP connections should be optimized based on the network status. In this paper, we propose an automatic parallelism tuning mechanism called GridFTP-APT (GridFTP with Automatic Parallelism Tuning) that adjusts the number of parallel TCP connections according to information available to the Grid middleware. Through simulations, we demonstrate that GridFTP-APT significantly improves the performance of GridFTP in various network environments.
