A data center network disaster recovery transmission method

Abstract

The invention discloses a data center network disaster recovery transmission method, comprising: a data sending end determines the priority of data streams according to the transmission time limit and data volume of the data streams, and independently adjusts the congestion window of each data stream according to the priority and the degree of congestion , and limit the sending rate of data streams with low priority when congestion occurs; set up a queue at the data exchange end to store the identification and priority information of the data stream to which the message belongs, and traverse the data stream when sending or receiving a message The queue determines the priority of the data flow to which the message belongs, and processes the message according to the priority. The technical method recorded in the present invention provides an end-to-end data center network disaster recovery transmission mechanism, which can maintain good performance even when the network load is large, and can achieve low delay, high throughput, and high burst tolerance , Easy to deploy, so that the large amount of data stored in the data center can complete the transmission of disaster recovery data in 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
