Supplementary Exam

Posted by Salil Kanhere Thursday 07 January 2021, 05:52:31 PM.

The Supplementary exam will be held on Tuesday 12th January from 12 noon. Students approved to sit the exam have been emailed specific details.

Final Exam Marks Released

Posted by Salil Kanhere Tuesday 08 December 2020, 05:01:58 PM, last modified Tuesday 08 December 2020, 05:23:38 PM.

The final exam marks are available in Moodle. You can check your response and the correct answers for all questions in Moodle: Part 1 and Part 2 .

553 students attempted the exam. Some statistics: Max mark possible: 40 , Max mark achieved: 39.88 , Min mark achieved: 2 , Average: 29.2 , Standard Deviation: 4.9 , 75% percentile: 32.88 , 50% percentile (median): 29.41 , 25% percentile: 26.54

Here is the histogram of marks.

Overall, the performance has been fantastic. Well done everyone .

A shout out to the following students on their excellent performance on the final:

Sophia Lin and Gary Bai: 39.88 (you both rock !!)

Kenvin Yu: 39

Timothy Brunette: 38

Victor Liu: 37.88

In light of this performance, I don't expect any scaling to be necessary. We are yet to enter the marks into our backend system and compute your final mark for the course. However, this should be a straightforward addition of the following fields: LabTotal, MidExam, Assign and FinalExam. We will have the final course mark ready by Friday.

Do remember that to pass the course, you must have secured at least 40% (14 marks or more) on the final exam . However, it is evident from the above statistics that the hurdle is not an issue for most students.

If you have any final comments or feedback, feel free to add them to this anonymous form .

I wish you all a wonderful summer break and best wishes for the future. Do stop by and say hello in person if you are on campus in 2021. Stay safe and may the force be with you, always !!

Good luck for the final exam

Posted by Salil Kanhere Thursday 03 December 2020, 06:12:39 PM.

Good luck everyone. Not meaning to be Captain Obvious but some advice:

• Moodle Exam Links: Part 1 (2pm - 3:05pm, Sydney time), Part 2 (3:10pm - 4:15pm, Sydney time)
• Zoom Links (only if you have questions or technical issues): Meeting 1 (password: 613574), Meeting 2 (password: 203331)
• Get a good night's sleep
• Have some food prior to the start of the exam
• Keep a water bottle handy
• Find a quiet and comfortable room where you are unlikely to be interrupted for the duration of the exam
• Make sure your computer is charged and connect it to a power outlet
• If you are on a shared network then make sure others using the network will not engage in heavy usage
• Download all lecture notes and homework questions to your computer to avoid potential bottlenecks with the WebCMS server
• Don't panic if a question stumps you, move on and come back to it later
• Remember to answer all questions in both parts (the # of questions in each part are stated on the front page).

May the force be with you all !!

Important Final Exam Tip: Download content on your local machine

Posted by Salil Kanhere Wednesday 02 December 2020, 05:13:45 PM.

I was told that earlier this week, the WebCMS server was slow for a sustained duration because many students were trying to access content simultaneously (possibly for an exam). COMP3331/9331 has over 570 students enrolled. I do not manage the WebCMS server so I cannot comment on the peak load of the server.

Thus, I recommend that you download all reference content that you may need for the final exam to your local machine. In particular, the lecture notes and the weekly homework Q&A would be good candidates.

Do remember to download the current versions if you have already done so in the past. Some minor edits may have been incorporated.

Assignment Marks Released

Posted by Salil Kanhere Tuesday 01 December 2020, 12:37:13 PM, last modified Tuesday 01 December 2020, 01:35:07 PM.

The marks for your assignment have been released. If marks were deducted then feedback is provided.

If you are not satisfied with the mark then DO NOT PANIC and DO NOT immediately send me an email. Your assignments were marked by your tutors. You can find their name on the Timetable page. You may cc our course administrator (Ayda) in your communication if you wish. I have requested the tutors to respond to any concerns raised by you and reach an amicable resolution while still ensuring fairness. If you believe you are not happy with this resolution, you can write to me.

Our plagiarism detection system has flagged 27 submissions to have a high overlap with other submissions. I find this very disappointing. We have withheld marks for these submissions. The students have been emailed regarding further actions which includes a meeting with me later today. A final decision on penalties will be made soon and marks should be visible by tomorrow.

Final Exam Reminder and Details

Posted by Salil Kanhere Monday 30 November 2020, 08:52:38 PM.

A reminder that the Final Exam will be held on Friday, 4th December from 2pm to 4:15pm .

The exam will be held online in Moodle and is made up of two parts: Part 1 (2pm - 3:05 pm, Sydney time) and Part 2 (3:10 pm - 4:15 pm, Sydney time). There is a 5 minute break between. You cannot start the second part of the exam before the noted time. You will not be able to return to the first part once you move to the second part. All unsaved attempts will be automatically saved when the time expires. I will remove the password protection on the exams closer to the exam time.

If you have questions or technical issues, you can join one of the following Zoom Meetings and contact me or one of the tutors: Meeting 1 (password: 008844), Meeting 2 (password: 203331). There is NO requirement to join these meetings.

There is extensive information about the final exam on the specific exam page including information on the examinable content, exclusions, preparation guide, etc. A practice exam is also available on the exam page in the same format (2 parts, each running for 65 minutes), which everyone is STRONGLY encouraged to attempt under exam-like conditions.

ELS students have been emailed about their specific arrangements.

I will run an exam consult ( Microsoft Teams ) on Wednesday, 2nd December from 4pm to 5:30pm . You are welcome to join and ask me any questions that you may have. When you join you

All the best and may the force be with you !!

Lab Marks + myExperience Feedback + Exam Reminder

Posted by Salil Kanhere Wednesday 25 November 2020, 05:24:28 PM.

A few announcements:

• Marks and feedback (if marks are deducted) for all labs are now available. You will also notice a "LabTotal" field is visible. This is computing by adding your 5 best lab marks and scaling the total to be out of 20 marks. This mark will constitute the lab component (worth 20%) of your final mark for the course. If you have any questions on the lab marking, please contact your tutor directly. The name of the tutor responsible for your lab is available on the Labs page.
• I understand that you are all busy with exam preparations. However, we would very much appreciate if you could complete the myExperience surveys for this course. We have reached a 30% response rate. Thanks to everyone who did their bit. However, I am sure we can do better. The survey closes on Thursday, 26th Nov , so please complete it as soon as possible.
• Assignment marking is on-going. We hope to have marks ready by middle of next week.
• A reminder that the final exam will be held on Friday, 4th December from 2:00pm to 4:15pm . Details are on the final exam page . A practice exam is available in Moodle and linked from the exam page. Answers to all homework questions are available to help you prepare for the exam.

Final Lecture + Final Exam Details

Posted by Salil Kanhere Friday 20 November 2020, 01:20:56 PM, last modified Friday 20 November 2020, 01:22:15 PM.

• The assignment deadline has now passed. Well done everyone !! We will accept late submissions subject to the penalties mentioned in the specification.
• Today is our final lecture . I will wrap up the remainder of the content on network security, recap what we have learnt in the course and discuss about the final exam (content coverage, logistics, type of questions, how to prepare, etc.). Come and say good bye.
• The final exam will be held on Friday, 4th December from 2pm to 4:15 pm (AEST) . It will be an online Moodle quiz in two parts. Part 1 will run from 2pm to 3:05pm. There will be a 5 minute break. Part 2 will run from 3:10pm to 4:15pm . Further details about the final exam including a link to a practice exam (in two parts) are available on the final exam page . Please make sure that you read all information on the page carefully.
• Please complete the myExperience surveys . The response late is rather low. I would appreciate a few minutes of your time.

Assignment Deadline Approaching (noon, Friday 20th November)

Posted by Salil Kanhere Wednesday 18 November 2020, 09:28:01 AM.

This is a reminder that the assignment deadline is about 2 days away - noon, Friday, 20th November .

Some important considerations:

• Submissions will be marked in the VLAB environment and through command line execution. It is thus imperative that you thoroughly test your code in VLAB before you submit. If we cannot execute your code then we cannot award you any marks. We appreciate that you might write your code on your personal machine and use an IDE. However, we are unable to test it in that environment. Please pay attention to this point to avoid any angst when marks are released.
• Make sure you test your code thoroughly to ensure consistent correct operations.
• We are primarily interested in testing the "normal" execution of client/server interactions in both configurations. We will test a few obvious error cases. However, it is not our goal to focus on a variety of edge cases.
• Make sure that your client and server programs print meaningful messages at the terminal. You are NOT required to follow the exact text shown in the sample interactions. You may choose your own.
• I have uploaded two sample binary files of different sizes to the assignment page. You may wish to use these for testing the functionality of UPD and DWN commands. We will use similar files (different sizes) in our tests.
• If you have created additional files (beyond the base server.* and client.*) then feel free to group them under two sub-directories ( server and client ) in your archive. This will be helpful for us while marking.

Good luck !!

Week 10: Final Week of Lectures, Assignment Deadline on Friday, Tutorials replace Labs

Posted by Salil Kanhere Monday 16 November 2020, 05:49:00 PM.

A few important announcements for this week:

• This is our final week of lectures . On Tuesday we will wrap up our short discussion on Wireless Networks and dive into the basics of Network Security. On Friday we will wrap up the leftover content on Network Security and I will discuss about the final exam. Come and say good bye !!
• Lab 6 is due by 11am Tuesday, 17th November . There will be a tutorial replacing the lab (in your usual Zoom/Teams meeting) this week. This will serve as useful practice for the final exam. Please look through the questions beforehand and try to solve them by yourself. All questions on the tutorial are from past exams. So effectively, it is a sample exam.
• Please complete the myExperience surveys . The response rate so far is rather poor. We would appreciate your feedback.
• The final exam will be held on Friday, 4th December from 2pm to 4:15 Sydney time online (Moodle) . Later this week I will make available several resources for the final exam including a practice exam. Stay tuned for further details.
• The assignment is due by noon on Friday, 20th November . This is a hard deadline. Assignment consults are running this week so seek help if you need it. A couple of additional points:
  • I have uploaded two sample binary files of different sizes to the assignment page. You may wish to use these for testing the functionality of UPD and DWN commands. We will use similar files (different sizes) in our tests.
  • If you have created additional files (beyond the base server.* and client.*) then feel free to group them under two sub-directories ( server and client ) in your archive. This will be helpful for us while marking.
• I know this is a busy week for everyone but make sure to not overwhelm yourself. Good luck with everything.

Updated Assignment Consultation Schedule for Weeks 9 and 10

Posted by Salil Kanhere Sunday 08 November 2020, 10:14:44 PM.

The assignment consultation schedule has been adjusted so that they are spread out across the remaining two weeks. Please check the revised schedule on the assignment page ( here ).

Mid-Term Exam Clarification: Part 1 Questions 7-10

Posted by Salil Kanhere Tuesday 03 November 2020, 08:36:58 PM.

Before you contact us about these questions please double check the marks awarded for them even if Moodle may indicate that your answer is wrong.

There are various ways to write up the required expressions. It was impossible for me to configure all possible combinations for automarking. I configured a few typical combinations for this. Next, I manually examined all answers deemed incorrect by automarking and awarded full marks for those that were correct (and partial marks if incorrect depending on the extent of the error). If you marks were updated manually, Moodle will show your answer to be incorrect (an X mark instead of a check mark). So please check the actual mark awarded for these questions before contacting us.

A number of announcements this week. Read carefully:

• Lab 2 deadline is 11am, Tuesday, 6th October.
• Lab 3 is released and will require you to get into the nitty-gritty of DNS and TCP socket programming.
• In the lectures this week we will first wrap up some of the left over content on the Application Layer and begin our journey into the Transport Layer.
• The assignment specification is available. It is long but for a reason. Read it carefully. Read it again (and again). The deadline is noon, Friday, 20th November (Week 10) . Assignment specific consultations will be arranged in Weeks 7-10. Details will follow. In the meantime, any questions should be posted as comments on the specifications page on WebCMS.

Have a great week and see you in lectures.

Week 3: Wrapping up Applications and Lab2

Posted by Salil Kanhere Monday 28 September 2020, 02:01:31 PM.

The first lab report is due by 11am, Tuesday, 29th September . Submission instructions are in the lab spec. Submissions received via email will not be entertained.

In the lectures, we will wrap up our coverage of the application layer, which includes e-mail, DNS, P2P and CDN.

In Lab 2 , we will explore HTTP and learn to use a new tool called Wireshark, a protocol analyzer. We strongly encourage you to install Wireshark on your machine (instead of running it through VLAB). It is free and works on all operating systems. Download it here . You will also get your first exposure to socket programming. Sample working client/server programs in C/Java/Python are available under the Week 1 lecture content.

Very few students appear to be attempting the homework questions . We strongly encourage everyone to work through these questions on your own. We will post answers for the collated questions (e.g. Introduction Questions). However, the questions marked with " Students to Discuss Solutions " are exclusively left for you to work on. We are happy to provide feedback on your attempts, but will not provide ready solutions. This should serve as excellent practice for the exams.

Have a great week and see you in lectures !!

Week 2: Labs begin and so does our journey into networked applications

Posted by Salil Kanhere Monday 21 September 2020, 10:45:26 AM.

This week in lectures, we will wrap up our introduction to computer networks (protocol layers) and dive into networked applications (principles, Web/HTTP, Email). A reminder that lecture videos are accessible through Teams, Youtube and Echo360. A Slack group is available for you to chat during the lectures. Do not use it to ask me questions. Questions during the lectures should be posted to the Teams Q&A. The forum on our website is the primary means to seek help and discuss about course content.

Labs will commence this week. Almost all labs are at full capacity. You MUST attend the lab class in which they have enrolled. The link to each lab class is posted on the Labs page . Recordings will be available. You will notice that there are two parallel lab classes, e.g., T14A and T14B. Make sure you attend the correct class as per your timetable. You are strongly urged to setup access to the VLAB environment prior to the lab . It is not an efficient use of your tutor's time if they have to explain this process to you during the lab. We encourage the use of TigerVNC. Check the instructions here . The first lab exercise is now available. You are strongly urged to read the Tools of the Trade introductory document available on the labs page prior to the lab. The first lab report is due by 11 am, Tuesday 29th September. Submission instructions are in the lab specification.

A number of problem solving questions are accessible on the Homework Questions page. You are strongly encouraged to work through these questions on your own. We will post answers for the collated questions (e.g. Introduction Questions). However, the questions marked with " Students to Discuss Solutions " are exclusively left for you to work on. We are happy to provide feedback on your attempts, but will not provide ready solutions. Working through these questions will provide good practice for the exams.

An early head's up that the mid-term exam will be held on Tuesday, 27th October (Week 7) during regular class hours (11am - 1pm). Mark this time in your calendar. The exam will be held online. Further information will be made available later.

Have a great week and see you in class on Tuesday & Friday !!

Some updates

Posted by Salil Kanhere Thursday 17 September 2020, 11:44:56 AM.

I have created a playlist in Youtube and Echo360 of the lecture recordings. Links are on the Lectures page. Echo360 will allow you to download the video if you wish to do so. Note that, there may be a slight delay (up to 24 hours) for the video files to be posted to these playlists. The video should be available immediately after the lecture concludes through the Teams links.

In response to several requests during the lecture, I have setup a Slack workspace for those attending the live lecture to chat. The link to join is here . This is not meant to be a distraction but as a means for those attending the lecture to discuss about the topics being covered in the lecture. Please be respectful and adhere to the CSE code of conduct. Questions for me MUST be posted to the Teams Q&A. The workspace should ONLY be used during the live lectures. It is NOT meant to replace the online discussion forum. Please continue to post questions to the forum. We will closely monitoring the workspace and if we observe that the above conditions are not adhered, then we will have to close it down.

Labs commence in Week 2. Links to individual lab meetings (and recording repositories) are posted on the Labs page. Most labs are at full capacity. Please attend the lab class in which you are enrolled. Students are strongly encouraged to test the VLAB environment prior to your lab. Information on accessing VLAB is on the course webpage. We recommend using TigerVNC.

A self-study lab which outlines the various networking tools that will be used in the labs is available for you to review. We encourage you to have a crack at these tools. This lab is NOT marked. The lab exercise for next week will be released after Friday's lecture.

See you in the lecture on Friday.
