Description
Technical Field
The invention relates to the technical field of flow control, in particular to a method and a system for controlling multidimensional concentrated flow, which are used for enterprise application integrated flow control.
Background
Flow control refers to limiting the number of access requests by taking some measure when resources become bottlenecks in the case of limited resources. Currently, the most common is the token bucket algorithm; the token bucket algorithm refers to that when a request comes in, a token is taken from the token bucket, and only the request carrying the token is processed. As shown in fig. 1, a schematic diagram of token bucket principle is shown; tokens in the token bucket are generated according to a certain rate, and the token bucket is limited by the size of the token bucket, so that whether the token bucket is full or not can be judged when the tokens are generated. This mechanism requires only fetching tokens from the bucket for the application, has low coupling to the application code, and the token bucket can accumulate N times the current limiting value of tokens to satisfy the instantaneous high-traffic scenario when the system is idle.
However, existing token bucket algorithms only throttle the caller, and do not throttle flow control to both the system itself and the backend service provider. The algorithm has no response mechanism, the service caller only takes the token to send the request, the token bucket generates the token at a certain rate as long as the token bucket is not full, and the whole flow is not conscious of whether the service provider is available. Therefore, when the token is sufficient, the service provider is blocked or otherwise unavailable, and the service caller takes the token and continuously sends requests to the backend, which may cause complete paralysis of the service provider system.
Thus, there is a need for a flow control scheme that can coordinate service invokers with service providers.

In one embodiment, in order to completely isolate the influence of other systems around the system on the flow control of the system during the flow control process, an independent virtual channel between the service caller and the service provider can be established to provide independent flow control between the service caller and the service provider.
The independent virtual channels include: the resources are exclusive resources.
In order to more clearly explain the above-mentioned control method of the multi-dimensional concentrated flow, a specific embodiment will be described below.
Taking the enterprise application integration platform 100 as an example, fig. 3 is a schematic diagram of a multi-dimensional flow control architecture according to an embodiment of the present invention. The enterprise application integration platform 100 is an integration switching center between enterprise applications, and is a key hub for application integration; in the process of enterprise application integration, the enterprise application integration platform 100 adopts multidimensional flow control, and can control a service provider and other dimensions besides the flow control of the dimension of a service calling party, so that the flow control can be more accurately performed; meanwhile, a queue mechanism is provided to enable flow control to be smoother, and the situations that tokens are sufficient and the system processing capacity is poor are solved.
Specifically, the dimensions of the multidimensional flow control include a combination of four dimensions of a service caller system, a service provider system, a service interface, and a service interface group.
Further referring to fig. 3, in the enterprise application integration platform 100, the flow controller 110 is composed of an access flow control module 111 and an access flow control module 112, where the two flow control modules are active and standby.
As shown in fig. 3, the enterprise application integration platform 100 provides flow control at both the service caller system outlet (front end flow control 111 ') and the service provider inlet (back end flow control 112'), both of which improve upon the token bucket algorithm.
The flow control dimensions of the front-end flow control 111' include: a service caller, a service ID, a service provider; the flow control dimensions of the back-end flow control 112' include: a service provider.
In connection with the control method of multidimensional concentrated traffic shown in fig. 2, first, when a service caller 200 initiates a request, the enterprise application integration platform 100 receives the request; further, by using the access flow control module 111, according to the set flow control dimension, tokens of the corresponding dimension are obtained from the token bucket and sequentially allocated to the requests;
after the request is assigned to the token, it is forwarded to the service provider for queuing on the message queue 120; message queues 120 are partitioned by service provider system;
each request is dequeued in sequence after a certain queuing process in the message queue 120, and the request dequeuing is controlled and adjusted mainly according to the process of the service provider 300 for processing the request; the dequeuing speed can be increased if the processing efficiency is high, and the dequeuing speed can be reduced if the processing efficiency is lower;
when the request queuing is finished, judging whether the request has a token for accessing the service provider or not by the output flow control module 112;
in the case of a token, the enterprise application integration platform 100 forwards the request to the service provider 300 and releases the token upon receipt of the return from the service provider 300. Through the multidimensional flow control process, the efficient and stable operation of the service calling party and the service provider can be ensured, and concurrent access exceeding the system load is prevented.
Further, as shown in fig. 4, a virtual channel architecture according to an embodiment of the invention is shown. In connection with fig. 4, in order to completely isolate the flow control interactions between the systems during the flow control process, a separate virtual channel 400 between the service invoker and the service provider may be established to provide separate flow control between the service invoker and the service provider.

For example, taking a service caller a and a service provider a as examples, a virtual channel is established between the two; on the virtual channel, it includes: the resources are exclusive on the enterprise application integration platform 100, which is equivalent to opening up a virtual resource channel from access to access on the platform, and are specially used for flow control of the service caller A and the service provider A.
In addition, corresponding virtual channels are respectively established among the service calling party B, the service calling party C and the service provider B. By setting up the virtual channel, the operation resource of the system can be ensured, the influence of the peripheral system on the system is completely isolated, and the operation stability of the system is further improved. Each virtual channel has a cache thread pool for access requests and access requests, and simultaneously has flow control.
