Simple Protocol
The sender sends packets one after another without even
thinking about the receiver.
, Stop-and-wait protocol
1. Sequence numbers field is one bit which is sufficient for achieving the unambiguous communication
sender and receiver
2. So, if the sequence numbers are based on modulo-2 arithmetic, i.e., sequence numbers of packets will be 0
3. Flow control is being achieved by letting the sender wait for an acknowledgment by the receiver for a sent p
4. Error control is being achieved by error detection/discarding the corrupt packets
5. The sender sense that either the packet has been discarded by the receiver or being lost when its timer exp
6. Delayed or lost packets are retransmitted
