Embodiment Construction

[0053] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0054] The self-adaptive congestion control method disclosed in the present invention includes: preset configuration file, the configuration file stores the failure rate of the control object and the corresponding concurrency number of the failure rate of the control object; calculates the current failure rate of the control object; The concurrent failure rate of the control object corresponding to the current failure rate of the control object; if the current concurrent number of the control object is greater than the concurrent failure rate of the control object, refuse to submit the target transaction.

[0055] Referring to Fig. 1, Fig. 1 shows a flow chart of the steps of a preferred embodiment of the adaptive congestion contro...

Abstract

A method for controlling adaptive congestion includes presetting configuration file stored with controlled object fault ratio and corresponding concurrent number of controlled object fault radio, calculating current fault ratio of controlled object, obtaining controlled object fault ratio concurrent number corresponding to current fault ratio of controlled object from configuration file and refusing to make transaction on provided object if current concurrent number of controlled object is greater than fault ratio concurrent number of controlled object. The device for realizing said method is also disclosed.

Description

technical field [0001] The invention relates to the field of data communication, in particular to an adaptive congestion control method and device. Background technique [0002] At present, network applications based on client / server architecture have affected people's lives everywhere. In such an architecture, servers often undertake important tasks, such as computing and storage. Especially in some large systems with high real-time requirements, the server needs to respond and process a very large number of transactions. In order to process transactions in a timely manner, a multi-threaded concurrent processing method is adopted inside the server. However, the resources of the server are limited, and the number of transactions that the server can process at the same time is also limited. Therefore, if the transactions are sent to the server without restriction, a large number of transactions will be waiting because they cannot be processed by the server. State, forming ...
