METHOD AND SYSTEM FOR CONTEXT-BASED RETRANSMISSION OF LOST PACKETS
This abstract first appeared for US patent application 18742891 titled 'METHOD AND SYSTEM FOR CONTEXT-BASED RETRANSMISSION OF LOST PACKETS
Original Abstract Submitted
State of the art data transmission approaches require all the lost data packets to be retransmitted, which may not be required in a variety of scenarios. Existing protocols lack the option to change packet semantics on the fly for individual fragments on the fly for the same stream. Also, parameters including maximum number of retransmissions permitted are set beforehand, one for entire stream. Method and system in embodiments disclosed herein provide an approach for context-based retransmission of lost packets. Method and system disclosed in the embodiments herein identifies one or more packets as lost packets based on reception status of acknowledgement (ACK) within a dynamically adaptive timeout period, and then based on value of a NRTx header field associated with the lost packet, determines whether or not to retransmit the lost packet. Value of the dynamically adaptive timeout period is recalculated dynamically, based on a determined instantaneous channel condition.
