METHOD FOR DYNAMIC CONTROL OF PACKET DATA TRANSMISSION Russian patent published in 2010 - IPC H04L12/56 

FIELD: physics; communications.

SUBSTANCE: method is disclosed for controlling packet data transmission from a server to a client which has client buffer in accordance with a standby mode and a dynamic mode. The standby mode is maintained until packets, which contain data encoded depending on the current bit transfer rate, reach the client buffer; otherwise the dynamic mode is executed. The standby mode allows step-down switching to lower bit transfer rates, but does not allow step-up switching to higher bit transfer rates. The dynamic mode allows step-up and step-down switching with regulation of bit transfer rate of packets, partially controlled based on amount of data contained in the client buffer when packets which contain data encoded depending on the current bit transfer rate reach the client buffer for the first time. Two modes help avoid unnecessary speed switching.

EFFECT: improved method of controlling stream switching to provide the user with more reliable and stable content.
