For the Go-Back-N pipelined protocol, how many out of 10 sequence packets will the receiver buffer?
Homework Answers
Answer: All, the 10 sequences will receive positive acknowledgement if the packets have been successfully transferred.
go back n, if negative acknowledgement is received then from that sequence, all further packets will be transferred again, until it received a positive acknowledgement.

Consider a Go-Back-N protocol with a sender window size of 5 and a sequence number range of 1,024, and assume the receiver sends ACKs with the number of the next sequence number expected. Suppose that at time t, the next in-order packet that the receiver is expecting is a packet with the sequence number 8. Assume that the channel does not reorder packets. (a) What are the possible sets of sequence numbers inside the sender’s window at time t? Justify...

1. For TCP end-to-end flow control, suppose the capacity of the
receiver buffer is 10 packets. Suppose the packets that are being
queued in the receiver buffer are packets 4, 5, 6, 7, 8, 10, 11.

13 at this moment? How about packet...

(a) In a sliding window protocol with RWS=SWS=5, a very large set of possible sequence numbers (assume no wrapping), and in-order packet arrivals, why can the receiver be assured -3- that it will never again receive the frame with sequence number 10 if it is currently expecting frame 17? (b) For the sliding window protocol, if the sender’s window size (SWS) equals the receiver’s window size (RWS), what is the minimum number of sequence numbers that are required? How many...

(a) Assume a Sliding Window with Go-Back N ARQ is being used on a transmission link with a 3-bit sequence number. The transmitter has previously sent frames with sequence numbers 0, 1 and 2. Is the transmitter allowed to send a frame with sequence number 3 if the frame with sequence number 2 has not been acknowledged? Explain your answer. (b) Assume a Sliding Window with Go-Back N ARQ is being used on a transmission link with a 3-bit sequence...
If 4-bit sequence number is used in protocol 5, what would be the size of buffer?...
If 4-bit sequence number is used in protocol 5, what would be the size of buffer? Why? Drawthe initial sender and receiver sliding windows. Draw the sender and receiver sliding windowsfor the situation where the sender has sent the first few frames and has stopped sendingbecause it has to now wait for an acknowledgements. Also the receiver has received all theframes that sender has sent so far and has sent all the acknowledgements. But the acknowledgements are lost

which of the following statements is not true for local DNS servers? Option: A local DNS server acts like a proxy. IPS often provide default name servers. A local DNS server provides authorization hostname to IP address mappings. A local DNS servers has a local cache to speed up. Which of the following is unlikely to be one of the transport layers services? Option: Segmenting Reliable data transfer congestion control host-to-host communication What is the data unit exchanged in the...

In Go-Back-N protocol, only one timeout timer (for the oldest unACKed packet) is maintained at the sender. Can you explain why this is sufficient?

(a) A data link with a 1 Gigabits/sec capacity is used to transmit packets made up of 1400 bytes of data and 100 bytes of protocol control information. Each packet is acknowledged by a short frame of size 150 bytes. The propagation speed in the transmission medium is 200,000 km/sec. Consider the buffering and processing time in the nodes to be negligible. A node A communicates with a node B, with a distance between nodes A and B of 16...
