Embodiment Construction
[0069] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the application. However, the present application can be implemented in many other ways different from those described here, and those skilled in the art can make similar promotions without violating the connotation of the present application. Therefore, the present application is not limited by the specific implementation disclosed below.
[0070] In order to more clearly demonstrate the flow control method provided in this application, firstly introduce the application scenario of the flow control method provided in this application, which is the first embodiment of this application. The flow control method provided in this application can be applied to the scenario of performing flow control on multiple service nodes in a distributed system.
[0071] Multiple service nodes in a distributed system may refer to servers for serving multiple users, and ea...

The embodiment of the invention provides a flow control method. The method comprises the following steps: obtaining the number of service nodes in a distributed system and a global flow control parameter; according to the number of the service nodes and the global flow control parameters, obtaining local flow control target parameters used for performing local flow control on the abnormal service nodes; and providing the local flow control target parameter to the service node, so that the service node performs local flow control on the abnormal service node. According to the method and the device, the local flow control target parameter is obtained through the number of the service nodes and the global flow control parameter, and when the connection state or the data transmission state between the service nodes and the global flow control node in the distributed system is abnormal, local flow control is carried out by using local flow control target parameter for abnormal service node. Compared with the prior art, the method has the advantages that the local traffic control target parameter is easier to obtain for the abnormal service node by using the local traffic control target parameter, and the obtained local traffic control target parameter can maintain the stability of global traffic control.
Description
technical field [0001] The present application relates to the field of computer technology, and specifically relates to three flow control methods, devices and two flow control systems. At the same time, it also relates to electronic equipment and computer storage media corresponding to the flow control method. Background technique [0002] A distributed system (distributed system) is a software system built on a network, and multiple service nodes are set up in the distributed system to handle various assisting tasks. In a distributed system, flow control is required so that each service node can normally handle various assistance tasks. Generally speaking, each service node is connected to the global flow control node, and when each service node is in a normal connection state with the global flow control node, the global flow control node performs global flow control on each service node. But once a service node "loses" contact with the global flow control node, the ser...
