Method, apparatus and system for realizing computer room-spanning data transmission

Abstract

The invention discloses a method, apparatus and system for realizing computer room-spanning data transmission. The method comprises the following steps: inputting to-be-sent data of a sending party computer room into a sending buffering unit; sending notification for being ready for receiving data to a receiving party computer room side and receiving buffer reception state information returned by the receiving party computer room side; and according to the buffer reception state information, sending the data in the sending buffering unit to the receiving party computer room side. According to the technical scheme, because the sending part will carry out data transmission according to the capability of the receiving party, the probability of data transmission failure can be reduced, thereby reducing the number of times of data retransmission and improving the data transmission efficiency.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method, device and system for realizing cross-computer room data transmission. Background technique [0002] In the context of today's information society, almost all Internet companies and other large enterprises store a large amount of information data. When the company has a wide range of businesses and data storage is distributed in different regions, it is inevitable that data transmission across computer rooms will be required. [0003] When data is transmitted across computer rooms, the main problem is: when data is transmitted across the public network across computer rooms, the failure rate is high, and a certain proportion of data is often lost, especially when the data from the telecom computer room is transmitted to the Unicom computer room (and vice versa. The same is true), the failure rate will be higher and the transmission speed will be slower wh...

Problems solved by technology

[0003] When data is transmitted across computer rooms, the main problem is: when data is transmitted across the public network across computer rooms, the failure rate is high, and a certain proportion of data is often lost, especially when the data from the telecommunications computer room is transmitted to the Unicom computer room (and vice versa. The same is true), the failure rate will be higher and the transmission speed will be slower when this kind of data transmission is performed across operators;

[0005] The existing cross-computer room data transmission methods have the following shortcomings: if the data transmission fails due to network congestion or the processing capacity of the receiving end is limited, a large amount of data retransmission at this time may aggravate the network congestion or cause the receiving end to go down. resulting in more data transfer failures
