Embodiment Construction

[0076] The DCN includes multiple sending points, multiple transmitting points and multiple receiving points. Wherein, the sending point, the receiving point and the transmitting point are all network devices. The sending and receiving points are, for example, switches, routers or servers. Transmission points are, for example, switches or routers. see figure 1 , figure 1 It is a structural schematic diagram of a DCN of the present application. figure 1 The shown DCN includes sending point 1 , transmitting point 1 , transmitting point 2 , receiving point 1 and receiving point 2 .

[0077] It should be understood that figure 1 It is only a schematic diagram of an exemplary structure of the DCN of the present application. In practical applications, the number of sending points, the number of transmitting points, and the number of receiving points included in the DCN may be more.

[0078] In an implementation manner of the present application, one sending point among multiple...

Abstract

The application discloses a transmission rate control method, device, sending device and receiving device. The transmission rate control method is applied to the DCN, including: the sending point receives the first CNP sent by the receiving point, and the first CNP includes rate information, and the rate information indicates that the receiving point receives the data flow included in the A receiving rate of data packets; determining the receiving rate according to the rate information; determining an emptying rate according to the receiving rate; updating the sending rate of the data flow to the emptying rate. In the technical solution of the present application, the sending point adjusts the sending rate of the data stream according to the rate information of the receiving point, and can accurately adjust the sending rate of the data stream, thereby eliminating queue congestion at the transmitting point and improving the transmission performance of the data stream.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a transmission rate control method, device, sending device, and receiving device. Background technique [0002] A data center network (DCN) is a core network for data transmission and is widely used in the field of network transmission. A typical DCN includes a sending point, a transmission point and a receiving point. The transmission point receives the data packet sent by the sending point and sends it to the receiving point. With the development of artificial intelligence, cloud computing, and real-time big data analysis, DCN should meet the requirements of ultra-low latency, high throughput, and no packet loss. Based on this, DCN supports remote direct memory access (RDMA) Data transfer scheme. [0003] Since network congestion can cause excessive data transmission delays and even packet loss, RDMA provides a data center quantized congestion notificatio...
