The Supplementary exam will be held on Tuesday 12th January from 12 noon. Students approved to sit the exam have been emailed specific details.
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 everyone. Not meaning to be Captain Obvious but some advice:
May the force be with you all !!
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.
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.
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 !!
A few announcements:
This is a reminder that the assignment deadline is about 2 days away - noon, Friday, 20th November .
Some important considerations:
Good luck !!
A few important announcements for this week:
I am told that WebCMS3 will be down for maintenance today (Saturday, 14th Nov) from 5-6pm Sydney time. If you require access to specific resources during this time, then please download them locally. Apologies for any inconvenience.
A number of announcements:
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 ).
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.
The mid-term exam marks are now available. You can check your response and the correct answers for all questions in Moodle: Part 1 and Part 2 . The final total is also available through WebCMS. We have been as generous as we can in awarding partial marks.
Want to find out how you fared compared to other students? Check out the class statistics available here .
The Faculty of Engineering has organised a webinar on research degrees (MPhil, PhD) in engineering on Wednesday 4th November from 1-2pm . Interested students should register here .
A few announcements this week:
Just in case some of you missed this due to being busy with exam preparations, assignment specific consults will commence this week and will run every week (Week 7 to Week 10). There are distinct slots for providing support in C, Java and Python. A timetable with links is posted at the bottom of the assignment page. The purpose of this session is to provide general guidance and help. Tutors are not expected to debug your code. Get in there early (this week for example) as the sessions get very busy closer to the deadline.
The WebCMS3 server was down overnight for a few hours due to some technical issues. My apologies but do note that the management of this server is outside my purview. To compensate for any potential inconvenience that this may have caused anyone, I have added 5 minutes extra to each part of the exam. So Part 1 will run from 11:10 to 11:50 and Part 2 will run from 11:50 to 12:30 . Timings for ELS students have also been adjusted accordingly.
Good luck everyone !!
I hope all of you enjoyed the bit of down time this past week and have used it well to prepare for the exam and get started with the assignment. Here are the key announcements for this week:
1) The Mid-term Exam will be held on Tuesday, 27th October .

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. 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).

3) Special assignment specific consultations will run every week from Week 7 to Week 10. There are dedicated sessions for C, Java and Python. You are encouraged to avail of these sessions if you need help. Note that, the purpose of this session is to provide general help and NOT for tutors to debug your code. The schedule is on the assignment page.
4) There will be no lecture on Tuesday. We will commence our journey into the network layer on Friday. Lecture slides are available.
In response to concerns about privacy, we have dropped the requirement for you to join the Zoom meeting and turn on your camera.
The meeting links will remain active and I and some tutors will be online. If anyone has any questions about the exam content and/or technical problems, then you can join one of the meetings and seek help.
I have updated the mid-term examination information page accordingly. The other guidelines and instructions remain unchanged.
The video that I made about the exam was recorded yesterday so do remember to ignore the part where I mention about turning on your camera.
Some students have indicated that they do not have a webcam. In this case, please connect to the Zoom meeting through your mobile phone and position the phone camera such that we can see your face.
WebCMS will be down for upgrades on Wednesday 21st October from 6pm - 9pm (Sydney time). Youtube and Echo360 videos should be accessible during this time. If you need access to any of the WebCMS hosted content during this time, then we suggest that you download those resources locally to your computer.
Apologies for the interruption but this is beyond our control.
A reminder that there are no labs or lectures this week . Students are encouraged to use this week to prepare for the mid-term exam and work on the assignment.
I have created a video where I go over the content included on the exam, exclusions, type of questions, preparation advice, etc. You can check it out on the Mid-term Exam page.
A reminder that the mid-term exam will be held during regular lecture hours (11am - 1pm) on Tuesday, 27th October (Week 7) . Details are on the Mid-term Exam page. I have organised a pre-exam consultation session on Friday, 23rd October from 16:00 - 17:30 . Meeting link is here .
Solutions for all homework questions are now available.

Check the information available on the Mid-term Exam page (includes information about content covered, exact timing, online meeting information, etc).
A sample online Moodle exam is available (with solutions). You are strongly encouraged to attempt the exam under conditions that will be consistent to when you sit for the real exam. This will familiarise you with the exam environment and the type of questions that you may expect.
We would strongly urge everyone to provide input on their choice of programming language for the assignment in this poll . This will help us to appropriately schedule programming help sessions in Weeks 7-10, as we plan to run distinct C, Java and Python help sessions.
You are welcome to provide anonymous feedback about the course through the following
A reminder that there are no lectures or labs in Week 6 . You are all urged to make use of this week to prepare for the mid-term exam and get cracking on the assignment. Good luck and may the force be with you !!
See you in the lecture on Friday.
Announcements for Week 5:
Have a productive week and see you all in the lectures.
A number of announcements this week. Read carefully:
Have a great week and see you in lectures.
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 !!
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 !!
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.
