Question

In a network using the Go-Back-N protocol with m = 3 and the sending window of size
7, the values of variables are Sf = 62, Sn = 66, and Rn = 64.
Assume that the network does not duplicate or reorder the packets.
a. What are the sequence numbers of data packets in transit?
b. What are the acknowledgment numbers of ACK packets in transit?In a network using the Selective-Repeat protocol with m = 4 and the sending window
of size 8, the value of variables are Sf = 62, Sn = 67, and Rn = 64. Packet 65 has already been
acknowledged at the sender site; packets 65 and 66 are received out-of-order at the receiver
site. Assume that the network does not duplicate the packets.
a. What are the sequence numbers of pending data packets (in transit, corrupted, or lost)?
b. What are the acknowledgment numbers of pending ACK packets (in transit, corrupted, or
lost)?
