Chained transmission method for large files in multi-machine environment

Abstract

The invention relates to the technical field of file transmission, in particular to a large file chained transmission method in a multi-machine environment, which comprises the following steps of: S1, setting a source host for transmitting data and a plurality of destination hosts for receiving the data; s2, electrically connecting a plurality of destination hosts in sequence, and marking the destination hosts at the two ends as a first host and a second host; s3, a receiving monitoring program and a forwarding program are set in the destination host except the second host, and a receiving monitoring program is set in the second host; s4, electrically connecting the source host with the first host; s5, the source host transmits a file to the first host, the first host receives a file transmission instruction through the receiving and monitoring program and starts to receive and download the file, the forwarding program forwards the received file to the next target host connected with the forwarding program, the next target host receives and downloads the file and forwards the file to the next target host, and the next target host receives and downloads the file and forwards the file to the next target host. And the second host receives and downloads the file.

Description

technical field [0001] The invention relates to the technical field of file transmission, in particular to a large file chain transmission method in a multi-computer environment. Background technique [0002] In a multi-host environment, one host transfers a large file with a unit of more than GB to other hosts. The file transfer time is limited by the number of hosts receiving the file, the CPU of the host, and the network bandwidth. When the number of hosts receiving the file is determined Yes, the file transfer time is mainly limited by the CPU and network bandwidth of the host. Better CPU performance of the host and better network bandwidth will help shorten the file transfer time. By optimizing the CPU performance of the host, the network bandwidth will increase. higher cost. [0003] Therefore, there are deficiencies in the prior art and need to be improved. Contents of the invention [0004] Aiming at the above-mentioned defects in the prior art, the purpose of th...

[0002] In a multi-host environment, one host transfers a large file with a unit of more than GB to other hosts. The file transfer time is limited by the number of hosts receiving the file, the CPU of the host, and the network bandwidth. When the number of hosts receiving the file is determined Yes, the duration of file transfer is mainly limited by the CPU and network bandwidth of the host. Better CPU performance of the host and better performance of network bandwidth are beneficial to shorten the duration of file transfer. By optimizing the CPU performance of the host, the network bandwidth will increase higher cost
