Claim 15:
16. A system, comprising:
a client instance hosted by a platform, wherein the client instance is accessible by one or more remote client networks, and wherein the system is configured to perform operations comprising:
detecting an initial Transmission Control Protocol (TCP) packet of a sequence of TCP packets transmitted from a source to a destination in a communication network;
detecting a retransmission request TCP packet transmitted from the destination to the source indicating a dropped TCP packet of the sequence of TCP packets during transmission of the sequence of TCP packets between the source and the destination, wherein the retransmission request TCP packet comprises a selective acknowledgement signal (SACK) in an enabled state indicating a gap in the sequence of TCP packets;
in response to detecting the retransmission request TCP packet, storing information from one or more data fields of the initial TCP packet, one or more data fields of the retransmission request TCP packet, or a combination thereof;
providing, via a user interface, an indication that the dropped TCP packet was dropped within a particular time window based on the stored information;
detecting a duplicate retransmission request TCP packet transmitted from the destination to the source indicating the dropped TCP packet of the sequence of TCP packets during the transmission of the sequence of TCP packets between the source and the destination; and
in response to detecting the duplicate retransmission request TCP packet, discarding the duplicate retransmission request TCP packet.
