摘要:
 在分布式环境中,不同的管理域之间的节点由于受到访问控制机制的限制,导致端到端的数据传输无法直接进行,因此必须借助数据源节点和目的节点之间的节点进行中转.此外,在复杂的分布式环境中,数据传输的源端和目的端之间存在多条传输路径,需要考虑在端到端的数据传输过程中如何对多条传输路径进行均衡利用,以提高数据传输效率.为此,利用端到端的数据传输的特点,基于缓冲区、数据分片、多路并行传输等技术,设计了一种适应高性能计算环境中的多路并行数据传输机制,研究了可靠性保证策略.理论分析表明,多路并行传输机制可以有效解决分布式环境下的数据传输访问控制和传输效率等问题,尤其是对于较为复杂的分布式环境下进行的大数据传输,该机制充分利用了整个网络环境的传输带宽,同时解决了中间节点的数据落地问题,为端到端的数据传输提供了高效可靠的保障.
Abstract:
 In distributed environment,nodes in different management domains can’’t transfer data to each other directly because of restrictions of access control mechanism,so that the end-to-end data transfer has to rely on the mid nodes between the source and destination to transit.In addition,there are more than one transfer path between the source and destination in complex distributed environments,and a way to utilize those transfer paths balanced to improve the end-to-end data transfer efficiency needs to be considered.According to the characteristics of end-to-end data transfer,an efficient end-to-end multipath parallel transfer mechanism has been designed with the technology of buffer area,data segmentation and multipath parallel transfer and effective strategies to ensure the transfer reliability.The results of analyses show that this mechanism has effectively solved the problems of access control and transfer efficiency in distributed environment which is a highly efficient and reliable transfer security mechanism for end-to-end data transfer,and that especially for big data transmission in more complex distributed environment,the bandwidth of the network environment could be made full use of and the problem of the data to disk on intermediate node has been solved.
