The question has parts: a,b,c,d and e.
Intro. To Telecommunications Assign#4 (d) Suppose the same situation as above but sender and receiver use Selective Repeat ARQ What frame(s) would the sender need to retransmit? Explain. 1. Suppose that a sender and a receiver are using ARQ to perform reliable data delivery. (a) In a Go-Back-N ARQ protocol, the window size is 6. Frames with sequence numbers 1, 2, 3, 4 and 5 have been sent. The sender just received an...

(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...

TCP at Packet Level In a TCP packet level data transfer, sender and receiver both have a window that can hold 4 packets. Sender has 5 packets to send numbered 0-4. ACK 2 is lost and PKT 3 is lost too. (Remember in TCP the ACK number is one greater than the number of the last packet received in order and that ACKs are cumulative) There are no other errors or losses in either direction. Draw a timeline diagram that...

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.
What is the advertised window size the receiver sent to the sender?
Suppose packet 12 is the last packet sent by the sender. What’s the
effective window size at the sender? Can the sender send out packet
13 at this moment? How about packet...

1. (1 pt) Under what conditions would an open-loop protocol such as an error-correcting Hamming code be preferable to the feedback type protocols discussed in Chapter 3? 2. (1 pt) Suppose that a stop-and-wait protocol was used on a channel has a 300 millisecond propagation delay and sender frames sizes of 100 milliseconds. The receiver must fully receive the frame before sending an acknowledgment. The size of the acknowledgment can be ignored. What is the channel utilization? 3. (1 pt)...
