This mechanism is called forward acknowledgment. If the recipient doesn\u2019t receive a segment, it will also let the sender know, using the same acknowledgment mechanism. In this case, instead of asking for the next piece, it asks for a piece that the sender has sent previously. The sender interprets this as indication that the previously-sent segment was lost somehow in transmission. The sender then resends the segment. This will be done again until the recipient gets the segment. Obviously, to do this, each segment must have some sort of ID . This ID is called sequence number, or SEQ.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
