Using only the data given in the text, what is the maximum number of telephones that the existing U.S. system can support without changing the numbering plan or adding additional equipment? Could this number of telephones actually be achieved? For purpose of this problem, a computer or fax machine counts as a telephone. Assume there is only one device per subscriber line.

3. Consider the M/M/1 queue discussed in class. Assume that packets arrive to a queue with average arrival rate A [pkts/s]. The average service rate of the queue is denoted by u [pkts/s]. (a) Write expressions for: (i) the mean time between packet arrivals to the queue, i.e., the average inter-arrival time; and (ii) the mean service time, i.e., the average time needed to transmit a packet onto the outgoing link. (b) Let N denote the number of packets in the system in steady-state. Suppose A = 850 and u 1000. Find the smallest value of B such that P(N > B) < e = 10¬4. Hint: Use MATLAB or some other computational tool (you could even use an Excel spreadsheet) to test different values of B. 4. Consider the M/M/1 queue from Problem 3. (a) Find an expression for E[N], i.e., the average number of packets in the system in steady- state. For the values of A and µ specified in Problem 4(b), compute the value of E[N]. What happens when A→ µ? (b) Find an expression for Var[N], i.e., the variance…
The previous problem is in the picture. Suppose that I have 800 Gigabytes worth of movies on my hard drive at home, and I’d like to get them to a friend in Chicago. I could either send them over the Internet, or I could copy them to a thumb drive, drive to Chicago, and deliver them by hand. Assume that the specs for my cable connection are the same as in the previous problem, but the friend in Chicago has a cable connection which gets 25 Mbps down/5 Mbps up. Which would be faster? Show your work.
This question is about the telephone network: How many end office codes were there pre-1984, when each end office was named by its three-digit area code and the first three digits of the local number? Area codes started with a digit in the range 2–9, had a 0 or 1 as the second digit, and ended with any digit. The first two digits of a local number were always in the range 2–9. The third digit could be any digit.
How do you write the statements to let the user enter an integer and a double value from the keyboard?
Suppose Alice and Bob are going to communicate using AES in CBC mode. Unfortunately Alice's message length (in bytes) is not a multiple of 16. Suppose the last block of her message is just a single zero byte. How can she pad out the last block so that she can use CBC mode? Since this needs to be a reversible operation, how does Bob recognize the padding and remove it?
For each of the following sets of codewords, please give the appropriate (n,k,d) designation where n is number of bits in each codeword, k is the number of message bits transmitted by each code word and d is the minimum Hamming distance between codewords. Also give the code rate. {111, 100, 001, 010}
Assume the following parameters for Selective Repeat (SR): a) N = 4 b) Round Trip Time (RTT) = 10 ms c) Timeout period = 40 ms d) Segment Size = 2200 bytes. Suppose that Bob sent 14 segments, numbered 1 to 14, to Alice using the SR mechanism. Suppose that Segment 4 and Segment 10 were lost the first time the segments were sent to Alice (but reached Alice correctly when retransmitted). Apart from the above, there were no other segment losses. What is the average throughput obtained in sending all the segments (in bytes/sec)? Draw a diagram to show the communication of the segments in detail.
A botanist is doing fieldwork assigns an eight-character alphanumeric code to each sample collected. The first character must be 6, 7, or 8; the next three characters can be any capital letter, A through Z; the fifth character could be any digit except for 0; and the rest of the characters can be any capital letter, B through K. Digits and letters can be repeated. Determine how many possible ID numbers there are using the fundamental counting principle, and explain each step. Show work for all steps Thanks
ARP and RARP both map addresses from one space to another. In this respect, they are similar. However, their implementations are fundamentally different. In what major way do they differ? Please give different Answer don't copy previously given Answer already checked them.
A) Assume there is a wide-area network with N nodes, where N ≥ 2 What is the smallest number of point-to-point communication links such that every node in the network is able to talk to every other node? (Note: A network in which some nodes are unable to exchange messages with other nodes because there is no path between them is called disconnected.)
Using the RSA algorithm, perform an encryption and decryption calculation of a Message M=32 using prime numbers p= 5 and q=11 Message M=25 using prime numbers p=11 and q=7 Message M=30 using prime numbers p=13 and q = 7
IN PYTHON Given the following six-node wide area network for which the numbers attached to the links are a measure of the “delay” in using that link (e.g., some lines could be more heavily used than others and therefore have a longer wait time), answer the following question. What is the shortest path from node A to node D, where shortest path is defined as the path with the smallest sum of the delays on each individual link? Explain exactly how you went about finding that path.
