. Answer the following questions related to the FSMS for the Go-back-N protocol with m = 6 bits. Assume the window size is 63. (Figure 23.27): a. The sending machine is in the ready state with Sy = 10 and S, - 15. What is the sequence number of the next packet to send? b. The sending machine is in the ready state with Sf = 10 and S, 15. A time-out= c. The sending machine is in the ready state with S= 10 and S₂ = 15. An ACK with ackNo= 13 arrives. What are the next values of S, and Sn? d. The sending machine is in the blocking state with S= 14 and S, = 21.What is the size of the window? e. The sending machine is in the blocking state with Sf = 14 and $₂ = 21. An ACK with ackNo = 18 arrives. What are the next values of Sfand S,? What is the state of the sending machine? f. The receiving machine is in the ready state with R₁ = 16. A packet with sequence number 16 arrives. What is the next value of R,? What is the
