Abstract

The invention discloses a multi-dimensional centralized traffic control method and system. The method comprises the steps: receiving a request initiated by a service caller; obtaining tokens of corresponding dimensions from the token bucket according to the set flow control dimensions, and sequentially distributing the tokens to the requests; forwarding the request to which the token is allocatedto a message queue of a service provider for queuing; after the request queuing is finished, judging whether the request has a token for accessing the service provider or not; and under the conditionthat the token exists, forwarding the request to the service provider, and releasing the token when receiving return information of the service provider. According to the method and the system, centralized flow control is combined with multi-dimensional control, so that accurate flow control is realized, concurrent access exceeding system load can be effectively prevented, and stable operation ofthe system is ensured; in addition, by establishing independent virtual channels, all systems are completely isolated in the flow control process, mutual influence is avoided, and the stability of system operation is further improved.

Description

technical field [0001] The invention relates to the technical field of flow control, in particular to a multi-dimensional centralized flow control method and system for flow control of enterprise application integration. Background technique [0002] Flow control refers to taking certain measures to limit the number of access requests when resources become a bottleneck in the case of limited resources. At present, the token bucket algorithm is most commonly used; the token bucket algorithm means that when a request comes in, a token is taken from the token bucket, and only the request carrying the token will be processed. Such as figure 1 As shown in , it is a schematic diagram of the principle of the token bucket; the tokens in the token bucket are generated at a certain rate, and due to the limitation of the size of the token bucket, it will be judged whether the token bucket is full when the token is generated. This mechanism, for the application, only needs to take tok...
