Method and system for realizing flow control, message main node, and token server

Abstract

The embodiment of the application discloses a method and system for realizing flow control, a message main node, and a token server. At least one message sub center of a distributed message system is a first message center main node; and a preset token number is set at the first message center main node. After the first message sub center receives a message issued by a message producer, the method comprises: the first message sub center sends an application message for token application to the first message center main node; the first message center main node returns a reply message confirming token application to the first message sub center and a current available token number is updated; and the first message sub center sends the message to a message consumer. According to the method provided by the embodiment of the application, a token usage rate of a distributed message system can be improved.

Description

technical field [0001] The present application relates to the technical field of data communication, in particular to a method for realizing flow control, a message master node, a token server and a system. Background technique [0002] A message system is usually used in a software system to transmit information. The message system can transfer information from one component in the software system to another in the form of messages. [0003] The architecture of a message system generally includes: a message producer, a message center, and a message consumer. Among them, message producers are used to send messages, and message consumers are used to receive messages. The message center is located between the message producer and the message consumer, and is used to coordinate the transmission of messages between the message producer and the message consumer. Specifically, the role of the message center includes receiving messages generated by message producers, and deliveri...

Problems solved by technology

[0012] In the process of implementing this application, the inventor found that there are at least the following problems in the prior art: each message sub-center generally has a different frequency of forwarding messages, and there will be two situations. One situation is that some message sub-centers The speed is fast but the number of tokens is not enough, which will cause the message published by the message producer to be stuck on the message sub-center or the transmission speed will be slowed down; another situation is that some message sub-centers have remaining tokens due to the slow forwarding speed , which will result in a waste of some tokens

From the above two situations, it can be seen that although the amount allocated to each message sub-center is equal, the frequency of forwarding messages of each message sub-center is different, resulting in an "unbalanced" allocation of tokens and token distribution Decrease in usage
