Data center network disaster recovery backup transmission method

Abstract

The invention discloses a data center network disaster recovery backup transmission method. The method comprises the following steps: determining, by a data sending end, the priorities of data streamsaccording to transmission time limits and data volume sizes of the data streams, independently adjusting the congestion windows of the data streams according to the priorities and congestion degrees,and limiting the sending rates of the data streams with low priorities in the case of congestion; and setting a queue for storing an identifier and priority information of the data stream to which amessage belongs at a data exchange end, and traversing the message to determine the priority of the data stream to which the message belongs when the message is sent or received, and processing the message according to the priority. The technical method recorded in the invention provides an end-to-end data center network disaster recovery backup transmission mechanism, which can maintain relatively good performance when the network load is relatively large, and can achieve low latency, high throughput, high burst tolerance and easy deployment, so that the transmission of disaster recovery backup data among a large amount of data stored in a data center can be completed within a short time.

Description

technical field

[0001] The invention relates to the field of data transmission. More specifically, it relates to a data center network disaster recovery transmission method. Background technique

[0002] With the rapid development of information technology, technologies such as big data and cloud computing have gradually been deeply studied and widely used, and have become hot spots in the industry. So far, many data-intensive applications relying on big data and cloud computing have been widely deployed, and the amount of data generated is also increasing. At the same time, the value of data has become increasingly prominent, both in the scientific and commercial fields. Therefore, DCN (Data Center Network, data center network), as the core infrastructure for storing and processing huge data, has increasingly high reliability requirements.

[0003] However, DCN will be damaged by natural disasters such as floods, earthquakes, tsunamis, typhoons, etc., resulting in region...

Examples

Embodiment Construction

[0043] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0044] This embodiment provides a data center network disaster recovery transmission method:

[0045] The data sending end independently adjusts the congestion window of each data flow according to the priority of the data flow and the degree of congestion, and limits the sending rate of the data flow;

[0046] A queue for storing the identification and priority information of the data flow to which the message belongs is set at the data exchange end. When sending or receiving a message, traverse the queue to determine the...
