Methods, systems, and computer readable media for updating sequence and acknowledgment numbers associated with replay packets

摘要

Methods, systems, and computer readable media for updating sequence and acknowledgment numbers associated with replay packets are disclosed. In one example, a method includes generating, at a sending peer node, a replay packet that includes a payload associated with a capture file packet and accessing, in the sending peer node, a sequence-differential (SEQ-DIFF) list using an original sequence number associated with the replay packet. The method further includes traversing entries in the SEQ-DIFF list, wherein each of the entries includes a sequence number and a payload length differential value, applying, for each traversed entry in the SEQ-DIFF list, the payload length differential value to the original sequence number to determine an updated sequence number for the replay packet, and transmitting, from the sending peer node to a receiving peer node, the replay packet that includes the updated sequence number.

1. A method comprising:
generating, at a sending peer node, a replay packet that includes a payload associated with a capture file packet; accessing, in the sending peer node, a sequence-differential (SEQ-DIFF) list using an original sequence number associated with the replay packet; traversing entries in the SEQ-DIFF list, wherein each of the entries includes a sequence number and a payload length differential value; applying, for each traversed entry in the SEQ-DIFF list, the payload length differential value to the original sequence number to determine an updated sequence number for the replay packet; transmitting, from the sending peer node to a receiving peer node, the replay packet that includes the updated sequence number; and in the event the payload of the replay packet is modified to include a payload length that differs from a payload length of the capture file packet, adding an entry to the SEQ-DIFF list, wherein the added entry includes the original sequence number and a payload length differential value, wherein the payload length differential number represents a size difference between a payload length of the replay packet and the payload length of the capture file packet.
