1. We have completed Week 5.
2. Week 6 is No-teaching week: no lecture and no lab next week. You'll rather prepare for the Mid-term exam. We will continue to provide support through Ed forum during Week 6 as you prepare for the Mid-term exam.
3. A practice Mid-term exam is now available on Inspera for you to attempt (see the details in the previous notice/announcement). This is a copy of a real past exam paper. It will be open for you until the morning of the 8th of July, but you can attempt it only once. So take it when you feel prepared.
4. The real Mid-term exam will open in Inspera in Week 7 at 2:05pm on Monday (08 July) and end after 75 minutes. There will be no grace period, so you will have to start at 2:05pm to avoid loss of any exam time. As this will take place during your regular lecture hours, there will be no lectures on Monday. The contents of Week 7, which are now available in WebCMS, will be covered during Thursday's lecture. More information about the real Mid-term exam along with the link to it will be announced later next week.
Have a good weekend and prepare well for the Mid-term exam!
Dear Students,
A practice exam is available here: Moodle link . The exam uses the Inspera platform , which will be used for both exams in this course.
The practice exam will be open from 9:00 AM, 28-06-2024 , to 9:00 AM, 08-07-2024 . You can only attempt the exam once, so activate it ONLY when you are ready to take it. Answers are available as feedback in Inspera after completing the exam. The questions that require manual marking won't be marked. You can examine the answers provided and compare them with your own. Everyone is strongly urged to attempt the exam. It will familiarize you with the Inspera assessment environment so there are no surprises on exam day. A PDF file with the exam questions and answers will be posted on the mid-term exam page in webcms.
Dear Students

You have completed 4 weeks of the term. Congratulations!
In week-4, we spent a fair bit of time learning the required constructs and concepts to build a reliable communication system over an unreliable network. Next week we shall study in detail how TCP implements them in practice. We shall also learn a number of other useful functions executed by TCP such as congestion control, without which the Internet would collapse. The lecture slides for Week-5 are released now for your review.
In Week-5, you will be solving problems during your lab hours instead of executing practical lab exercises. The problem solving session will be a preparation opportunity for your Mid-term Exam, which will take place in Week 7. Later in Week-5, we shall also try to release a mock-test on the Inspera platform for you to have a trial of your Mid-term Exam.
The census date for the term is 23 June. While we do not encourage it, this is the last day that you can drop the course without incurring fees.
Have a great weekend but don't forget to work hard!
Hope to see you next week Monday in the lecture.

We have completed the Application Layer in Week-3. Congratulations!
In Week-4, we shall begin our journey into the Transport Layer of the Internet. The slides for Week-4 are now available for your review.
Here is a
poll on the pace of the lectures
. Let me know your thoughts so I can make adjustments as necessary.
Labs have started in full swing. Note that even you miss attending the actual lab session, you can still submit your lab report by the report submission deadline without any penalty using the on-line submission system. That is, there is no marks allocated for the attendance per se, but the marks are based on the submitted report.
Enjoy your weekend but don't forget to work hard as always.
See you Monday next week in the lecture.
Congratulations! You have completed TWO weeks!
Note that Monday (10 June) is a Public Holiday, so there will be no lectures on Monday in Week 3. Instead, we shall cover the remaining contents of Application Layer (DNS, P2P, CDN, Socket) during our Thursday lecture. Lecture slides are now available under Week-3 in WebCMS for your review.
Don't forget to submit your Lab-1 report by its due date, 10am Tuesday 11 June, to avoid late submission penalty.
Very few students appear to be attempting the homework questions. We strongly encourage everyone to work through these questions on their 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. Please post your solutions on the Ed forum. We are happy to provide feedback on your attempts. This should serve as good practice for the exams.
An anonymous feedback form is available
here
in case you wish to leave us some comments. We value your feedback and will try our best to act on your input.
Have a nice long weekend (but also work hard!).
Due to the public holiday on Monday, June 10th, the affected labs will be replaced with the following online sessions.
https://webcms3.cse.unsw.edu.au/COMP3331/24T2/reso...
Please attend these sessions as scheduled and they will also be recorded. Note that this change applies only to Monday, June 10th, of Week 3. Regular classes will resume from Week 4 onwards.
Congratulations! You have now completed the first week! Under Week-1 lecture, I have now released an additional slide set with answers to the in-lecture quizzes we discussed during Week-1 lecture.
In Week 2 lectures, we will complete our introduction to computer networks, i.e., discuss the layers of the Internet (cake:-), and dive into the top layer (Application Layer) covering networked applications (principles, Web/HTTP, and Email). Week-2 lecture slides are now released for review.
Labs will commence in Week 2. Please attend the lab class
you have enrolled in,
as many classes are at full capacity. Don't forget to submit the lab report by its due date, as they will be assessed.
Several problem-solving questions are accessible on the
Homework Questions
page. You are strongly encouraged to work through these questions on your own. These are not assessed. We will post answers for the collated questions (e.g. Introduction Questions). However, the questions marked " 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. Please discuss them on the Ed forum.
See you Monday 2pm next week in the lecture.
Have a great weekend (but also work hard!).
