Current limiting method and device

Abstract

Embodiments of the present disclosure provide a current limiting method and device, the method includes: monitoring the access volume of each node in the preset current limiting binary tree, the node has a current limiting threshold; if a target abnormal node in the node The visit volume of the target abnormal node is greater than the current limiting threshold of the target abnormal node, then determine the abnormal client and normal client from the clients corresponding to the target abnormal node; assign the current limiting threshold of the target abnormal node to the abnormal client and normal client, and get Abnormal sub-nodes corresponding to abnormal clients and normal sub-nodes corresponding to normal clients; and access control based on the updated current-limiting binary tree. In this disclosure, when the client is abnormal, the current limiting threshold of the corresponding node of the abnormal client can be allocated to the abnormal client and the rest of the normal clients, thereby preventing the abnormality of one client from affecting the access of other normal clients, reducing labor costs, Improved the accuracy of the current limit threshold.

Description

technical field [0001] Embodiments of the present disclosure relate to the field of network technologies, and in particular, to a current limiting method and device. Background technique [0002] In the network service, the server provides the service, and the client accesses the server to obtain the corresponding service. When there are many clients, the pressure on the server is high. At this time, current limiting is usually used to control the client's access to the server to reduce the pressure on the server. [0003] In the prior art, there are mainly two solutions for limiting the current of the client. Wherein, the first solution mainly sets a general flow-limiting threshold for the server, and when the traffic of the server reaches the flow-limiting threshold of the current limiter, the client is denied access to the server. The second solution mainly sets a current limiting threshold for each client, and when the access volume of the client reaches the correspond...

AI Technical Summary

Problems solved by technology

[0004] The inventor conducted research on the above schemes and found that, for the first scheme, if one of the clients causes the access volume to exceed the threshold, the access of all clients will be rejected, which will affect the access of other normal clients; for the second scheme, each client It is difficult to determine the current limit threshold of the terminal, and when the number of clients is large, the labor cost of the current limit threshold is high. In addition, it is impossible to accurately allocate the traffic that the server can bear to each client
