Problems solved by technology
[0007] To sum up, in the existing technology, the line traffic allocation of the distributed system is carried out according to the fixed traffic quota, and the transaction traffic of each line cannot be adjusted dynamically, which leads to the technical problems of overloading some lines and waste of line resources of some lines

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, which are used to realize the dynamic adjustment of transaction flow on lines in a distributed transaction system. The method of the present invention includes: obtaining the current transaction flow of each line, the current transaction flow of each line is determined according to the transaction data recorded in the transaction database in the current time period; according to the current transaction flow of each line and each line The corresponding group identifier determines the current total transaction flow of each group; for any group, if the current transaction total flow of the group is higher than the group’s maximum flow limit, the traffic of the lines in the group is adjusted until the group is in the process of traffic adjustment The total traffic flow of the subsequent transactions is lower than the maximum flow limit of the group. Through the above method, when the total transaction flow of a group exceeds the maximum flow limit of the group, the traffic adjustment of 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 ...
