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...

Find the optimum with random bit errors by taking the derivative and setting it to zero for the following protocols: (a) Stop-and-Wait ARQ (b) Go-Back-N ARQ (c) Selective Repeat ARQ (d) Find the optimum frame length for a 1 Mbps channel with 10 ms reaction time, 25-byte frame length ny that maximizes transmission efficiency for a channel overhead, 25-byte ACK frame, and p 104, 10-5, and 10-6.

please answer the question clearly.
Sliding window protocol with window size of 7 frames are used between the data link layers of machines A and B. Assume that machine B sends an ACK (acknowledgement) for every frame it receives without error, and it sends a NAK (negative acknowledgement) for every frame it receives with error. This corresponds to a receiver window size of 1 frame. Assume also that no frames are lost in the transmission medium. For the scenario shown...

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...

In the last module you learned a formula for calculating bit rate, R = b/t, that is the number of bits divided by the time. This formula expresses the number of bits that are transmitted over a circuit in a given period of time. In practice, however, we are not only concerned with the number bits transmitted, but also with the number of data bits transmitted over a circuit. The data bits are those that the sender decides to send...

Computer Networks help: True/False questions and a reason (if applicable) as to why it is true or flase: 1. The TCP receiver sends an acknowledgment of sequence number n if it has correctly received byte n. T/F 2. The main motivation of TCP flow control at the sender is to avoid network congestion. T/F 3. When losses are present, Selective Repeat schemes are more efficient than Go-Back-N schemes. T/F 4. Congestion control can be implemented on an end-to-end basis or...
