Problems solved by technology

[0002] Data transmission between data centers can be directly transmitted using the TCP protocol. When the amount of data to be transmitted between data centers is large, a large amount of bandwidth will be occupied, and the rental cost of these bandwidths is high.
[0003] At present, tunnel technology can be used to realize data transmission between data centers, but there are the following problems. On the one hand, when the data packet reaches the maximum transmission unit MTU (Maximum Transmission Unit), it needs to be fragmented, and the fragmentation process is relatively complicated; On the one hand, equipment failure will cause link disconnection and affect data transmission

Abstract

The invention provides a data transmission method between data centers. The data transmission method between the data centers includes the following steps that a first compressed data package is obtained after first data to be transmitted are compressed by a first server of a first data center and sent to a first acceleration device through a first interchanger, the first compressed data package is accelerated through the first acceleration device, the first acceleration device sends the first accelerated compressed data package to a second interchanger of a second data center through the first interchanger, the second interchanger sends the first compressed data package to a second acceleration device, the second acceleration device restores the first accelerated compressed data package to obtain the first compressed data package, and the first compressed data package is sent to a second server through the second interchanger. The data transmission method between the date centers can achieve flow control aiming at different application programs and has high efficiency and usability. The invention further discloses a data transmission system and a subsystem of the data transmission system.

Description

technical field [0001] The invention relates to the technical field of computer communication, in particular to a data transmission method, system and subsystems between data centers. Background technique [0002] The data transmission between data centers can be directly transmitted using the TCP protocol. When the amount of data to be transmitted between data centers is large, a large amount of bandwidth will be occupied, and the rental cost of these bandwidths is high. [0003] At present, tunnel technology can be used to realize data transmission between data centers, but there are the following problems. On the one hand, when the data packet reaches the maximum transmission unit MTU (Maximum Transmission Unit), it needs to be fragmented, and the fragmentation process is relatively complicated; On the one hand, equipment failure will cause link disconnection and affect data transmission. Contents of the invention [0004] The present invention aims to solve at least o...
