GO Classes Test Series 2024 | Mock GATE | Test 14 | Question: 12
Consider the sender's view of the sequence numbers in Go-Back-N protocol. Suppose the first sequence number in the sender's window is $k$, and the last sequence number in the sender's window is $k+3$. Let a packet with sequence ... must have been sent. If $p_{k+2}$ is not sent, then $p_{k+1}$ must not have been sent.

Go-Back-N
In Go-Back-N protocol (with an ACK/NAK response time within three frame transmissions) there are constantly new frames to be transmitted. The frames are numbered with 3 bits and all numbers 0, 1, . . , 7 are used. The length of the transmission ... the 3rd and 9th transmission. Give the transmission window and receive window for the first 18 frames, and the numbering of the frames.

The frames are numbered with 3 bits and all numbers 0, 1, . . , 7 are used. The length of the transmission window is 2 (and the length of the receive window is 1 due to Go-Back-N). The first frame has the number 0. Errors occur in the 3rd and 9th transmission. Give the transmission window and receive window for the first 18 frames, and the numbering of the frames.

Sliding window, Go-Back-N protocol, All ack lost case
I understood that receiver will correctly discard the frames in GBN all ack lost case. But its given that its positive ack and hence receiver wont send ack for discarded frames.Wont the sender be sending the same frames again and again ... timeout as receiver will never send ack again? So how will the sender slide the window to the next frames?

Can someone please suggest weather to go for 20.5 or 21 in these kind of problems in GATE? As logically 21 is correct, but mathematically 20.5 is correct. Both the answers can be reasoned correct and wrong, feels like “Umpire’s call” in DRS, cricket.

In the GO back N ARQ sender is sending the 20 packets to the destination with a window size of 4. Every sixth packet is lost and after a packet loss sender is sending one dummy packet outside the window for ensuring everything is correct [ dummy packet is an outside packet not the part of the window]. How many number of transmissions will be there?
