  • Programming Tutorial and Assignment Consultations

    Posted by Isura Bamunusinghe Arachchige 2 days ago, last modified a day ago.

    We hope your preparations for the midterm exam are going well. Good luck!

    We will begin offering you support for the programming assignment through a programming tutorial in Week 7 and consultation sessions from Weeks 7 to Week 9 (until Thursday, July 31st).

    Programming Tutorial (Revised Timetable)

    In Week 7, we will hold a programming tutorial instead of the usual lab session. The goal is to help you get started with the programming assignment. Please review the tutorial specifications in advance. We will extend the Webserver from Lab 3 to support additional features, some of which may directly carry over to the assignment. The tutorial will have separate slots for Python, C, and Java, so attend the session based on your preferred language. Please check the revised timetable for week 7. Note that this tutorial is not graded or requires no code submission. Starter code is available for you to practice. Sample solutions will be made available by the end of week 7.

    Assignment Consultations

    Special assignment-specific consultations will be available weekly from Week 7 to Week 9 as per the schedule here . There are dedicated sessions for C, Java, and Python. You are encouraged to attend these sessions if you need help. The schedule may be updated occasionally, so please check it before attending (e.g. the location of the in-person session). Please note that the purpose of these sessions is to provide general assistance with programming, not for tutors to debug your code.

    As the deadline approaches, we will aim to add more consultation slots based on demand, and any changes will be announced accordingly.

    However, we expect everyone to attend the programming tutorial in Week 7 to get a solid start on the assignment.

  • Week-5: Let's continue transport layer with TCP

    Posted by Mahbub Hassan 14 days ago.

    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. This week (Week-5) 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.

    There will be no lecture or labs in Week-6. Your Mid-term Exam will take place in Week 7, Tuesday (15 July) 4pm. You'll be able to take the exam on-line from anywhere (do not have to be on-campus). Later this week, we shall post more details of the Mid-term exam and also try to release a mock-test on the Inspera platform for you to have a trial.

    Due to the severe weather conditions, we will deliver the lecture on-line using Zoom. The Zoom link has been posted in the previous notice.

    Stay safe. See you at the Zoom lecture at 4pm.

    In Week-4, we shall begin our journey into the Transport Layer of the Internet.

    Here is a poll on the pace of the lectures . Let me know your thoughts so I can make adjustments as necessary.

  • Reminder to Join the COMP3331/9331 Course Forum

    Posted by Isura Bamunusinghe Arachchige about a month ago.

    The course forum is an essential platform for staying up to date with announcements, asking questions, and receiving support from instructors and fellow students.

    We strongly encourage you to join the forum as soon as possible to ensure you do not miss any important information or assistance throughout the term.

    You can access the forum at the following link:

    https://discourse01.cse.unsw.edu.au/25T2/COMP3331/

    Please note that questions submitted through Echo360 during live lectures are not monitored.

    To enhance your learning experience, we encourage attending lectures in person whenever possible. Alternatively, you can use the course forum to ask questions or discuss lecture-related topics.

  • Week-2: What's coming up?

    Posted by Mahbub Hassan about a month ago.

    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 discuss the layers of the Internet (cake:-), and dive into the top layer (Application Layer) covering networked applications (principles, Web/HTTP, and Email).

    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 Discourse forum.

    See you at 4pm in the lecture.
