METHOD AND DEVICE FOR RETRANSMITTING DATA VIA USER DATAGRAM PROTOCOL Russian patent published in 2017 - IPC H04L1/18 G11C8/04 

FIELD: physics, communications.

SUBSTANCE: invention relates to digital communication systems, and specifically to methods of retransmitting data via a user datagram protocol (UDP). Method comprises comparing a current user datagram with a previous datagram. In case of detecting a loss, a mechanism for re-requesting the lost datagram is launched, which is executed until the lost datagram is obtained. In the device, a payload processing unit includes a lost datagram read and search control unit, a re-request timer, a lost datagram search unit, a unit for reading useful data from a useful data storage unit, a recorded/read datagram counter, an overhead information recording unit, a payload data receiving unit, a useful data recording unit, a FIFO unit, a datagram read and search multiplexer, and the payload processing unit of the transmission unit includes an error packet forming unit, a re-request system control unit, a processed data counter, a transmitted data counter, a useful data recording unit, a useful data multiplexing unit, a useful data read unit.

EFFECT: invention reduces data loss while maintaining high speed characteristics.
