Problems solved by technology

[0013] The purpose of the present invention is to provide a method and system for communication flow control. Through the present invention, the problem in the prior art that the system processing capacity cannot be effectively utilized due to the fact that only the CPU occupancy rate is used as the basis for flow control is solved.
Solve the problem in the prior art that the effective processing rate of the system decreases due to the direct discarding of messages without distinction
[0014] In addition, the purpose of the present invention is to provide another method and system for communication flow control, which solves the problem in the prior art that the processing rate of valid messages decreases due to the fact that the message packets that have failed due to excessive delay are not eliminated. question

Embodiment Construction

[0109] The invention provides a method and system for controlling communication flow, the core of which is: the main control module obtains the comprehensive parameters of the internal queue length and the average residence time of message packets in the internal queue, or the detection result of CPU occupancy; When the obtained comprehensive parameter or the CPU occupancy detection result data exceeds the set threshold, the communication flow is controlled through the set global shared parameter.

[0110] The principle diagram of the first embodiment of a system for controlling communication flow provided by the present invention is as follows figure 2 As shown, it includes: input buffer 00, output buffer 01, admission module 02, scheduling module 03, internal queue 04, main control module 05, flow control module 06 and configurable global shared parameter database 07.

[0111] The input buffer 00 is used to buffer the message packets from the previous link;

Abstract

The invention discloses a control method and system of flow capacity, which comprises the following steps: obtaining synthetic parameter or of even retention time in the inner array for inner array length and message or detecting result of CPU occupying rate; controlling flow capacity through setting global sharing parameter when the obtained parameter or detecting result exceeds the setting threshold value. The invention guarantees the precision of system overload condition, which improves effective disposal rate of system and information.

Description

technical field [0001] The present invention relates to the fields of electronics and communications, and in particular, to a method and system for flow control. Background technique [0002] In the field of electronics and communications, system resources such as CPU processing power, timers, memory buffers, etc. are very limited. With the increase of system communication traffic, each communication process often fails to allocate system resources, and the connection request is abnormally terminated. The load on connection requests is heavier. When the connection request load is too heavy, the CPU usage may be too high, resulting in a sharp drop in system performance and a decrease in the density of successful calls. [0003] Decreased density of successful calls means lower connection rates, lower throughput, and higher communication delays. The greater the ratio of rejected calls to the total number of calls, the faster the rate of throughput decline, which will eventu...
