NAK free reliable data transfer protocol
Reliable data transfer over a loss channel with bit error rdt3.0 figure shows the sender FSM for rdt 3.0 a protocols that reliable data transfer over a channel that can corrupt or loss packets: figure shows how the protocols operates with no lost or delayed packets and how it handles lost data packets. In figure time moves forward from the top of the diagram toward the bottom of the diagram note that a receive time for a packet is necessarily later than the send time for a packet as a result of transmission and propagation delays. In figure and the send side brackets indicate the times at which a time is set and later times out. Because packet sequence numbers alternate between 0 an 1 protocols rdt 3.2 sometimes knows as the alternating bit protocols.
