Go-Back-N ARQ

Retransmission begins with the last unacknowledged frame even if subsequent frames have arrived correctly .duplicate frames are discarded.

Go-back-n ARQ -- Receiver must get Frames in correct order

Selective Repeat ARQ

Only the unacknowledged frame is retransmitted.

It may be (slightly) more efficient than Go-back-n ARQ, but also much more complicated.

Selective repeat ARQ -- correctly-received out-of-order Frames are stored at Receiver until they can be re-assembled into correct order
