分析了继基于传统互联网的网格之后出现的一种新型网络——光子网格网络的研究目标与特点,研究了光子网格中数据传输的机制。在此基础上给出了一种基于网格文件传输协议(GridFTP)的面向光子网格中大文件传输的多通道并行传输机制。理论分析和数据传输实验结果表明,这种机制可以有效地降低呼叫阻塞率和缩短时延,在有大文件传输需要的网格应用中能获得更好的性能,同时这种机制的引入也进一步提高了光子网格的传输性能。
This paper analyzes the research objective and data transmission characteristics of the optical grid following the traditional grid based on the Intemet, and on the basis of this, proposes a multi-path parallel transmission scheme based on the grid file transfer protocol (GridFTP) for bulk-data transmission in optical grid. The results of the theoretical analysis and data transmission experiment show that the scheme can effectively reduce call block and time delay and perform well in grid applications in need of transmitting bulk data. The introduction of the scheme can further improve the performance of optical grid systems.
