The implementations described in the following exemplary examples are not representative of all implementations consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as detailed in the accompanying claims.
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
For a clear understanding of the technical solutions of the present application, the prior art solutions will be described in detail first.
With the continuous development and scale expansion of the internet financial industry, the explosive development of internet financial services such as online shopping, online financing, online loan and the like, the relation of the mutual calling of the information systems of the financial transactions is also gradually complicated. Banking information systems generally face large-scale request transactions, if a preceding node in the system cannot detect service acceptance capability of a subsequent service node in a synchronous mode, and further cannot limit transaction flow to be forwarded to the subsequent service node, a great deal of occupation of progress and thread resources of the preceding node can be caused when the response time of the subsequent service node is abnormally increased, and chain reaction occurs when serious response occurs, so that the system is paralyzed.
Currently, traffic is limited by the number of requesters requesting, for example: the request transaction is firstly placed in the container, if the request waiting to be processed is overlarge, the container overflows, and the effect of rejecting part of the transaction is indirectly achieved, so that the flow is limited. Currently Google provides a token bucket algorithm based throttling tool to implement the throttling function, the principle of the token bucket algorithm is that the system puts tokens into the bucket at a constant speed, and if a request needs to be processed, a token needs to be acquired from the bucket first, and when no token is advisable in the bucket, service is refused.
However, the number of requests that the container can carry is preset, and cannot be dynamically adjusted according to the actual conditions of the transaction, and if the number of requests is improperly set, the flow cannot be effectively limited. The current-limiting tool performs too single function and lacks flexibility.
Therefore, the inventor finds in the research that the current transaction flow limiting mode cannot effectively limit the flow, further determines a corresponding transaction server according to the transaction request sent by the user terminal, acquires the current service timeout rate corresponding to the transaction server, and determines a corresponding flow limiting grade according to the current service timeout rate, so that whether the transaction request is limited according to the flow limiting grade is determined, if so, the transaction request is intercepted, the transaction request is not forwarded to the transaction server, and if not, the transaction request is forwarded to the transaction server. The current service timeout rate is used for determining the current limit level, so that whether the transaction request is forwarded is determined according to the current limit level, and compared with the existing current mode of limiting the current transaction amount, the current limit method is more reasonable, the current limit method can effectively limit the transaction amount, and the load of a server can be ensured not to exceed the limit.

As shown in fig. 1, the network architecture corresponding to the transaction flow limiting method provided in the embodiment of the present invention includes: a user terminal 1, a local server 2 and a transaction server 3. The local server 2 is communicatively connected to the user terminal 1 and the transaction server 3, respectively. If the user needs to verify the transaction password during transaction operation, for example, online shopping, the user can perform transaction operation through the user terminal 1, and the user triggers a transaction request through the user terminal 1. The local server 2 receives the transaction request sent by the user terminal 1 and determines a transaction server 3 corresponding to the transaction request; acquiring the current service timeout rate corresponding to the transaction server 3, and determining the current limiting grade corresponding to the transaction server 3 according to the current service timeout rate corresponding to the transaction server 3; determining whether to limit the flow of the transaction request according to the corresponding flow limit level of the transaction server 3; if not, forwarding the transaction request to the transaction server 3; if not, intercepting the transaction request, generating the current limiting prompt information and forwarding the current limiting prompt information to the user terminal 1. The transaction server 3 receives the transaction request and performs a corresponding transaction operation, such as verifying the transaction password, according to the transaction request. The current service timeout rate is used for determining the current limit level, so that whether the transaction request is forwarded is determined according to the current limit level, and compared with the existing current mode of limiting the current transaction amount, the current limit method is more reasonable, the current limit method can effectively limit the transaction amount, and the load of a server can be ensured not to exceed the limit.
