Dynamic management of packet loss

A non-transitory computer-readable medium storing instructions, which when executed by a processing device, cause the processing device to perform a method comprising:

• determining an amount of packet loss in transmitting packets to a destination computing node;
• determining, based on the amount of packet loss, a duplication pattern for a plurality of packets to be transmitted to the destination computing node as a sequence of packets, wherein the duplication pattern includes (i) a number of candidate packets of the sequence of packets to be duplicated, (ii) a number of first duplicates of each of the candidate packets, and (iii) a spacing between the first duplicates;
• duplicating a first packet within the plurality of packets according to the duplication pattern, including generating one or more duplicates of the first packet and spacing the one or more duplicates within the plurality of packets according to the spacing between the first duplicates;
• transmitting the plurality of packets including the one or more duplicates of the first packet to the destination computing node;
• receiving a first acknowledgement from the destination computing node;
• and
• in accordance with a determination that the first acknowledgement is directed to a duplicate of the first packet:
• in accordance with a determination that a second acknowledgement has yet to be received for each of a first one or more packets within the plurality of packets transmitted prior to the duplicate of the first packet, retransmitting the first one or more packets to the destination computing node.

An apparatus comprising:

• a processing device;
• and
• a memory coupled to the processing device, the memory storing instructions which, when executed by the processing device, cause the apparatus to:
• determine an amount of packet loss in transmitting packets to a destination computing node;
• determine, based on the amount of packet loss, a duplication pattern for a plurality of packets to be transmitted to the destination computing node as a sequence of packets, wherein the duplication pattern includes (i) a number of candidate packets of the sequence of packets to be duplicated, (ii) a number of first duplicates of each of the candidate packets, and (iii) a spacing between the first duplicates;
• duplicate a first packet within the plurality of packets according to the duplication pattern, including generating one or more duplicates of the first packet and spacing the one or more duplicates within the plurality of packets according to the spacing between the first duplicates;
• transmit the plurality of packets including the one or more duplicates of the first packet to the destination computing node;
• receive a first acknowledgement from the destination computing node;
• and
• in accordance with a determination that the first acknowledgement is directed to a duplicate of the first packet:
• in accordance with a determination that a second acknowledgement has yet to be received for each of a first one or more packets within the plurality of packets transmitted prior to the duplicate of the first packet, retransmit the first one or more packets to the destination computing node.
