Methods and systems for resending missing network data packets

A non-transitory, machine-readable storage medium having stored thereon instructions for performing a method, comprising machine executable code which when executed by at least one machine, causes the at least one machine to:

• track, by a remote direct memory access (RDMA) layer of a second node, an offset value in a header of each data packet from among a plurality of data packets received from a first node, each data packet having a portion of a total payload, and the offset value indicating a starting point in bytes of each portion within the total payload,
• wherein the header includes a total payload size,
• wherein the first node and the second node provide access to storage via a cloud environment;
• based on the tracking, detect, by the second node, a missing data packet from among the plurality of data packets;
• transmit, by the second node, a message to the first node indicating an offset value of a missing payload of the missing data packet;
• and
• receive, by the second node, the missing payload of the missing data packet and any other data packet with an offset value that occurs after the offset value of the missing payload resent by the first node, without tracking individual data packet serial numbers,
• wherein the first node tracks data packet transmission, the offset value of each data packet and the total payload size, and in response to receiving the message, identifies any data packet with the offset value that occurs after the offset value of the missing payload of the missing data packet.

A system, comprising:

• means for tracking an offset value in a header of each data packet from among a plurality of data packets received from a first node, each data packet having a portion of a total payload, and the offset value indicating a starting point in bytes of each portion within the total payload, wherein the header includes a total payload size, wherein the first node and the second node provide access to storage via a cloud environment;
• means for detecting, by the second node, based on the tracking, a missing data packet from among the plurality of data packets;
• means for transmitting, by the second node, a message to the first node indicating an offset value of a missing payload of the missing data packet;
• and
• means for receiving, by the second node, the missing payload of the missing data packet and any other data packet with an offset value that occurs after the offset value of the missing payload resent by the first node, without tracking individual data packet serial numbers;
• wherein the first node tracks data packet transmission, the offset value of each data packet and the total payload size, and in response to receiving the message, identifies any data packet with the offset value that occurs after the offset value of the missing payload of the missing data packet.

A method, comprising:

• tracking, by a remote direct memory access (RDMA) layer, an offset value in a header of each data packet received from a first node for a transaction identified by a transaction identifier, each data packet having a portion of a total payload, and the offset value indicating a starting point in bytes of each portion within a total payload;
• detecting, by the second node, a missing data packet;
• communicating to the first node an indication of an offset value of a missing payload of the missing data packet;
• and
• receiving, by the second node, the missing payload of the missing data packet and any other data packet with an offset value that occurs after the offset value of the missing payload resent by the first node, without tracking individual data packet serial numbers.
