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...

AI Technical Summary

Problems solved by technology

Although D 2 TCP has improved compared to DCTCP, but experiments have shown that when the network load is too large, D 2 The performance of TCP will degenerate to DCTCP, resulting in a large number of streams that cannot be transmitted within its transmission time limit

Since DCN often needs to transmit a large amount of data in disaster recovery, D 2 TCP is also not suitable for the transmission of disaster recovery data in DCN
