METHOD OF CONTROLLING DATA FLOW IN SWITCHING CENTRES WHEN CONNECTING HETEROGENEOUS NETWORKS Russian patent published in 2009 - IPC H04L12/56 H04L12/46 

FIELD: information technology.

SUBSTANCE: invention relates to data flow control in asynchronous discrete data transmission networks with packet switching, particularly to systems for controlling traffic through a packet switching centre. For this purpose in the proposed method of controlling flow of data packets through a switching centre, occupance rate and rate of change of the free space of the buffer memory of the switching centre are calculated. Establishment of the functional relationship between occupance rate and rate of filling up of the buffer memory allows for limiting traffic such that, flow of data packets with higher priority have minimum restriction. Intensity of input streams is changed through adaptive variation of available memory allocated for packets of each stream when filling the next elementary memory unit.

EFFECT: increased probability-time parametres for transmitting messages under intermittent traffic conditions due to reduced probability of failure of reception of packets of high-priority traffic while retaining maximum possible low-priority traffic level through adaption of available memory of switching centres for packets of different data streams to its rate of filling with these packets and free memory.
