Problems solved by technology
However, because the leaky bucket algorithm uses single-point current limiting and the rate is fixed, it cannot cope with burst traffic requests; the token bucket algorithm is easy to cause hot spots, and the counter method is generally used for single-node current limiting, which is difficult to apply to distributed clusters

The embodiment of the invention discloses a flow control method and device, and a distributed cluster, which relate to the field of communication technology, and can combine the distributed cluster with the ZooKeeper cluster to realize multi-dimensional access flow control in a distributed environment. The method includes: the control device acquires initialization information; and sends the initialization information to the ZooKeeper cluster; the control device accumulates the flow of the first node device in a predetermined period according to a specified dimension, obtains the accumulated flow, and passes the first node device to The accumulated flow is sent to the ZooKeeper cluster; the control device obtains the flow of the second node device of at least one dimension according to at least one predetermined cycle; and the flow of the second node device of at least one dimension is accumulated to generate the total of the first node device Traffic, comparing the total traffic with a preset threshold to determine whether to perform a traffic-limiting operation on the first node device. The embodiment of the present invention is applied to a communication system.
Description
technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a flow control method and device, and a distributed cluster. Background technique [0002] For Internet distributed concurrent systems, in order to prevent instantaneous high-concurrency scenarios from exceeding the system's carrying capacity and ensure stable operation of the system, it is necessary to establish access flow control functions and set corresponding traffic thresholds according to different dimensions to achieve the function of restricting access. The counter method adopted by the existing flow control scheme is mainly used to limit the total number of concurrency within a certain period of time, such as the number of concurrency in database connection pools, thread pools, and spikes; Threshold limits the flow. The core idea of the leaky bucket algorithm is to assume a constant rate of outgoing requests with a fixed capacity, ...
