The size of the sending window determines the sequence number of the outbound frames. If the sequence number of the frames is an n-bit field, then the range of sequence numbers that can be assigned is 0 …
WebbLet's assume that sender S sends 3 packets: pkt1 (seq # = 100), pkt2 (seq # = 200), and pkt3 (seq # = 300), but pkt2 gets lost in transmission. With GBN: When the receiver R gets pkt1: It sends ACK=200, telling the sender that it has received all the bytes up to (but not including) 200 and is expecting byte 200 next.
WebbIn Go-Back-N ARQ method, both sender and receiver maintain a window. The sending-window size enables the sender to send multiple frames without receiving the acknowledgement of the previous ones. The receiving-window enables the receiver to receive multiple frames and acknowledge them.

However, the receiver in protocol rdt.2.2 can already handle duplicate packets. (Receiver-side duplicates in rdt 2.2 would arise if the receiver sent an ACK that was lost, and the sender then retransmitted the old data).
