Q 5- Assume that in a distributed system, the max clock skew of two different computers is 3
minutes. If the max clock drift is a * 0 0000001 seconds, calculate how often clocks should be
synchronized in that distributed system? You should write the solution on a paper and upload
the clear image,
(a = the last digit of your student number For example, if your student number is 123456 a is
6.)
6. Consider sending over HTTP a Web page that consists of one video clip, and five images.
Suppose that the video clip is transported as 25 frames, and each image has 4 frames.
a. If all the video frames are sent first without interleaving, how many "frame times"
are needed until all five images are sent?
b. If frames are interleaved, how many frame times are needed until all five images
are sent.
Write a program to simulate the behaviour of the CSMA/CD protocol over Ethernet when there
are N stations ready to transmit while a frame is being transmitted your program should report the times when euch station successfully starts sending its frame. Assume that a clock tick occurs once every slot time (57.2 usec) and a collision detection and sending of a jamming sequence. takes one slot time. All frames are the maximum length allowed

- You are the designer of a transfer protocol to send/receive a file between two computers. The sender divides the file into smaller frames to be sent sequentially to the receiver, and there are two options to make sure that receiver receives the file correctly: The sender can send frame n+1 if receives an ACK on frame n from the receiver (e.g., sender receives ACK on frame 2, so will proceed and send frame 3). The sender sends all the frames sequentially and the receiver will send only one ACK if the entire file is received successfully.

What is the risk with this scheme? (There was a real instance where applicants to a college admissions site could, after logging into the Web site, exploit this loophole and view information they were not authorized to see; the unauthorized access was however detected, and those who accessed the information were punished by being denied admission.)arrow_forwardAssume we have a client using a web browser that is directly connected to a web server. We are assuming there is a direct link between the client and the server. The RTT delay between the client and the server is 10 msec. The time it takes the server to transmit an object to its outgoing link is 2 msec. Now suppose that the client has the web page that it wants already cached locally. But the user wants to constantly check for updates and sends conditional get requests one after the other 20 times -- that is, once it gets a response and/or the updated object it sends out the next request. If we are using persistent HTTP and the cached object is up-to-date 40% of the time, how much time will elapse between sending the first request and the completion of the last one?arrow_forward
- A messaging system reads message as 4-digit positive integer d1d2d3d4 and stores encoding of the message e1e2e3e4 for security reason.

Consider a client and a server, separated by an RTT of 4 time units. The client makes a request for 4 objects at t=0. O1 consists of 10 frames, 02 and 04 each consist of 1 frame, and 03 consists of 2 frames. In the HTTP/2 example shown below, the server is transmitting frames to the client in the order 01, 02, 03, 04 (as long as there are frames of type i to transmit, and when not the server just moves on to a frame from object i+1 mod 4). Each frame takes 1 time unit to transmit. server GET O4 GET 03 GET O2 GET 01 object data requested client O4 O2 Оз Under HTTP 1.1 (not shown below), the server would send 01, 02, 03, O4 in that first-come-first-served (FCFS) order, sending each object in its entirety before moving on to send the next object in that order.

- Suppose that there are three stations labelled A, B, and C, where A and C are transmitting while B is receiving. The stations are in a configuration such that the two transmitters A and C are not in the radio range of each other. Since station C is out of the radio range of A, it does not know the presence of A. That’s why C perceives that channel B is free and starts transmitting to B. Also ‘A’ transmit signal at the same time to Channel B. The frames are garbled and a collision occurs. This is shown in the following figure: I. What is the name of this problem? II. How can we overcome this problem?arrow_forwardDevelop a simulation program to simulate an 8-port Ethernet switch. The switch initially has no knowledge about the hosts connected to each port. It learns frame addresses and stores-and- forwards the frames. The input text file "in.txt" contains information of the incoming frames, one frame per line. There are 4 pieces of data per line: frame ID, arrival port, frame source address, and frame destination address. The frames arrive at the switch in the order of which they appear in the input file. Destination address "X" indicates a broadcast frame. The output text file "out.txt" has 8 lines. Each line lists all the frames departing from each port, here is an example: "in.txt" contains 5 incoming frames: F1 P2 B--A F2 P6 D--C F3 P5 E--B F4 P7 F--D F5 P6 D--X "out.txt" should list the departing frames on each port: P1: F1 F2 F5 P2: F2 F3 F5 P3: F1 F2 F5 P4: F1 F2 F5 P5: F1 F2 F5 P6: F1 F4 P7: F1 F2 F5 P8: F1 F2 F5 Iarrow_forwardConsider for a minute that you are a software engineer who has invented a system that analyzes photos of a range of recyclable items (such as a can, bottle or a crate). It is accessible through a Web Application Programming Interface (Web API), which allows users to transfer photos over the internet.
