Here to determine the sequence of interlayered data sequence number that is bsn and ack number for the message sent at t equals to 2, t equals to 3, t equals to 4 and t equals to 5.

Let's analyze the ret 2 .2 sender and receiver fsm transmitter transmissions.
01:42
The feature that is the key feature of ret 2 .2 are that it uses both positive acks and negative acks and that it can retransmit data on time.
02:34
It also can retransmit data on timeout.
02:53
Here the behavior of ret 2 .2 sender and receiver at each time.
03:04
Ret 2 .2 sender and receiver at each time step.
03:24
First one is at t equals to 2 that is dsn data sequence number.
03:44
Here the sender sends a data packet with sequence number 0 that is dsn.
03:53
Sender is dsn equals to 0.
04:01
At receiver the data and sends receives the data and sends a positive ack with sequence number 0 that is receives data and sends a positive ack with sequence number 0 that is ack equals to 0.
04:48
Here second one at t equals to 3 the ack number.
04:58
Sender receives the positive ack with ack number 0...
