Embodiment Construction
[0063] In order to realize the dynamic adjustment of the transaction flow of the line, the embodiment of the present invention provides a line flow control method, by grouping the lines, when performing flow control, the current transaction flow of each line is obtained, and according to the current transaction flow of each line The group identification corresponding to each line determines the current total transaction flow of each group. When the total transaction flow of any group exceeds the group maximum current limit of the group, the flow of the line in the group can be adjusted to reduce Reduce the total transaction flow of the group, and then realize the dynamic adjustment of the transaction flow of the line, and solve the problem that the line flow distribution of the distributed system is carried out according to the fixed flow limit in the prior art, which leads to the technology that the transaction flow of each line cannot be adjusted dynamically question.

The invention discloses a line flow control method and device used for realizing dynamic adjustment for transaction flow of lines in a distributed transaction system. The line flow control method comprises the steps of obtaining a current transaction flow of each line, wherein the current transaction flow of each line is determined based on transaction data recorded in a transaction database within a current time bucket; determining a current total transaction flow of each group based on the current transaction flow of each line and a group identifier corresponding to each line; and for any group, performing flow adjustment for the lines in the group until the total transaction flow of the group after being subjected to the flow adjustment is lower than the highest group flow limit of the group if the current total transaction flow of the group is higher than highest group flow limit of the group. Through the line flow control method, when the total transaction flow of one group is beyond the highest flow limit of the group, flow adjustment for the lines in the group can be realized.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a method and device for controlling line traffic. Background technique [0002] Today's online trading systems usually adopt a distributed architecture, with multiple servers processing transactions at the same time and using one or more database servers to store transaction data. In order to ensure that the system can still operate normally when it is overloaded (that is, the number of external transaction requests per unit time exceeds the maximum transaction volume that the system can handle), it is usually necessary to design an overload protection function, that is, flow control. [0003] A common method of flow control is: configure a separate flow control parameter for each line of each server, such as the maximum limit of the line, and this flow control parameter is only used to determine whether the flow of the line corresponding to ...
