[0042] Step 301: Obtain the transmission capability information of at least one intermediate node between the previous node and the subsequent node, and the congestion information of the subsequent node;
[0043] Step 302: Determine the first delivery rate based on the congestion information of the subsequent nodes; determine the second delivery rate based on the transmission capability information of at least one intermediate node;
[0044] Step 303: Based on the first delivery rate and the second delivery rate, adjust the delivery rate of the preceding node.
[0045] Here, the execution subject of steps 301 to 303 may be a processor of the control device, and the control device may be located in the token authorization module.
[0046]In the embodiment of the present invention, the previous node, the intermediate node and the subsequent node may be routers or switches in the switching netwo...
Embodiment 2
[0099] Based on the same inventive concept, an embodiment of the present invention also provides a network congestion control device. Figure 7 It is a schematic diagram of the composition and structure of the network congestion control device in the embodiment of the present invention, such as Figure 7 As shown, the device includes: a processor 701 and a memory 702, wherein,
[0100] The processor 701 is used to execute the program stored in the memory 702, so as to realize the following steps:

Abstract
The embodiment of the invention discloses a network congestion control method and device, a chip and a storage medium. The method comprises the following steps: acquiring transmission capability information of at least one intermediate node between a preceding-stage node and a backward-stage node, and congestion information of the backward-stage node; determining a first issuing rate based on thecongestion information of the post-stage node; determining a second issuing rate based on the transmission capability information of the at least one intermediate node; and adjusting the issuing rateof the preceding-stage node based on the first issuing rate and the second issuing rate. Thus, the network congestion degree can be reduced, and smooth data flow is ensured.
Description
technical field [0001] The invention relates to the communication field, in particular to a network congestion control method, device, chip and storage medium. Background technique [0002] There are multiple measures in the computer networksystem to ensure the smoothness of data transmission and avoid network congestion. [0003] Such as figure 1 As shown, the unicast data arrives at the front-end module A, and sends the data packet information to the authorization request module, and the authorization request module sends the token request and the data packet information to the authorization distribution module in sequence. The authorization distribution module distributes tokens to the authorization request module according to the remaining authorization, data message information and message priority, and the authorization request module sends control information to the front-end module A according to the token to control the data delivery of the front-end module A. Wh...
