  • Final Mark and Statistics

    Posted by Salil Kanhere Saturday 11 December 2021, 02:26:08 PM, last modified Saturday 11 December 2021, 02:26:38 PM.

    We have ported the final exam marks from Inspera and computed your final course mark. You should find these through WebCMS. A reminder that you need to score at least 16 marks on the final to pass the course.

    Final exam statistics and shout outs to students who did exceedingly well in the course are available in the slides here .

    Well done everyone.

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

  • Final Exam Marks Released in Inspera

    Posted by Salil Kanhere Thursday 09 December 2021, 04:44:43 PM, last modified Thursday 09 December 2021, 04:45:43 PM.

    The final exam marks and your answers are now visible in Inspera. You can access it through the exam link on the Moodle course page. Answers and explanations are available as general feedback for each question. Marker comments have been added for manually marked questions when marks were deducted and for the issue noted below. You will find these in the "Student Report".

    We will port the exam marks to WebCMS and compute your final mark over the weekend. We will not be scaling the final exam marks, so you can compute your final mark by simply adding the following four components: FinalExam from Inspera (out of 40) + MidtermExam (out of 20) + Assignment (out of 20) + LabTotal (out of 20). To pass this course your final mark should be at least 50 AND your final exam mark should be at least 16 . If Inspera shows you a Pass or Fail grade, please ignore it.

    Important Note (please read carefully):

    I have manually checked all of your answers for the Distance Vector question where there was a typo in one version of the question for the poisoned reverse part of the question and to account for the late announcement from the exams unit. I have overridden the automarking and awarded additional marks where I saw a logical reason to do so to account for this issue. So please check the marks awarded even if Inspera may report your answer to be partially incorrect. A comment has also been added to this effect.

    I will announce the honour roll of students who did well in the course and class statistics on Monday. Well done everyone. I have enjoyed teaching this course and we hope you found it useful. I wish you the best for the remainder of your studies and your next adventure if you are graduating. If you are on campus in 2022, stop by and say hi.

  • Good luck for the final exam

    Posted by Salil Kanhere Sunday 05 December 2021, 05:52:46 PM.

    Good luck everyone. I don't mean to be Captain Obvious but some advice:

    • The exam link will be visible on the course Moodle page - HERE . You should navigate to the bottom of the page and find the Final Exam activity. The exam runs from 13:45 to 16:00 Sydney time tomorrow ( Monday, 6th December )
    • If you have technical issues with Inspera, reach out to the Exams support team. Their information is noted on the Moodle page. If you have questions about the exam, you can join THIS Zoom link and ask your question in the chat. DO NOT TURN ON YOUR MICROPHONE.
    • 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/answers 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.
    • Remember to breathe !!

    May the force be with you all !!

  • Practice Final Exam + Assignment Deadline

    Posted by Salil Kanhere Thursday 18 November 2021, 11:14:41 AM.

    This is a reminder that the assignment deadline is a little over 24 hours away - noon, Friday, 19th November.

    A reminder again that 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 it. 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 frustration when marks are released. Remember to test your code thoroughly in VLAB.

    Good luck !!

    A practice final exam is now available in Inspera. The Moodle link is posted on the Final Exam page. Y ou can only sit this exam once and it will close in 2 hours + 15 minutes after you start the attempt. Please keep this in mind before attempting the exam. You should be able to view the correct answers in Inspera after you submit your attempt. I strongly encourage you to attempt the practice exam in Inspera to ensure that you are comfortable with the Inspera platform so that there are no surprises in the final exam.

    I have also posted 2 PDF versions of the exam (one with just questions, the other with both questions and answers) on the Final Exam page.

    Good luck with the practice exam and other exam preparation.

    I will arrange for exam-specific consults over the next 2 weeks. Time/Date information and Zoom links to follow.

  • Week 3: Wrapping up the application layer + Lab 2

    Posted by Salil Kanhere Friday 24 September 2021, 10:14:06 AM.

    The Lab 1 report is due by 10 am Tuesday, 28th September . Submission instructions are in the lab spec. Submissions received via email will NOT be entertained. Do also note the requirement to submit a TAR archive. It is easy to create one using the command line tar utility in Linux (VLAB) or on Mac OS. On Windows, you can use 7-zip and on Mac OS you can alternately use Unarchiver .

    In the lectures, we will wrap up the leftover content from last week (trailing bits of HTTP, E-mail) and study DNS, Peer to peer applications and socket programming. Slides are available for review.

    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 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 Ed . We are happy to provide feedback on your attempts. This should serve as excellent practice for the exams.

    You can join the Ed Discussion forum via the following link - https://edstem.org/au/join/quFx6f

    An anonymous feedback form is available here in case you wish to leave us some comments. We will try our best to act on your inputs.

  • Week 2: What's Coming Up

    Posted by Salil Kanhere Friday 17 September 2021, 10:41:24 AM.

    In the Week 2 lectures, we will wrap up our introduction to computer networks (protocol layers) and dive into networked applications (principles, Web/HTTP, Email). Slides are available for review.

    Labs will commence in Week 2. Please attend the lab class in which you have enrolled as many classes are at full capacity. 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., W15A and W15B. Make sure you attend the correct class as per your timetable. You are strongly urged to set up 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 lab prior to the first lab. The first lab report is due by 10 am Tuesday 28th September (Week 3). 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. Please discuss them on the Ed Discussions Forum . You can join the forum via the following link: https://edstem.org/au/join/quFx6f

    An early head's up that the mid-term exam will be held on Monday 25th October (Week 7) during regular class hours (9 am - 11 am). Mark this time in your calendar. The exam will be held online. Further information will be made available later.

    Please complete the following polls if you haven't already: Poll 1 (Internet Speed) and Poll 2 (Your location)

    Have a great weekend, stay safe and see you online during the lectures on Monday & Wednesday !!

  • Reminder: Lecture today (Tuesday @ 9:30am)

    Just a quick reminder that I will be recording the 2nd lecture of this week today (Tuesday @ 9:30 am) - ZOOM LINK (password: 7empest).

    There won't be a live lecture tomorrow (Wed). Starting next week, we will follow the timetabled slots for the lectures on Monday (9 am) and Wednesday (12 noon).

    The lecture recording will be available later today in the Echo360 and Youtube playlists.

    Apologies for the inconvenience.

  • One-off Rescheduling of Lecture

    Posted by Salil Kanhere Monday 13 September 2021, 12:16:42 PM, last modified Tuesday 14 September 2021, 08:54:00 AM.

    As discussed in the lecture today, I have to participate in a roundtable on "Blockchain in Education" organised by Blockchain Australia that clashes with our live lecture time on Wednesday, 15th September.

    I will thus be pre-recording the 2nd lecture of this week on Tuesday, 14th September from 09:30 am - 11:30 am . If you have time and would like to join, here is the Zoom link (password: 7empest). It would be more fun and useful to have an interactive lecture. The recording will be available in the Echo360 and Youtube playlists. We won't have a live lecture on Wednesday, 16th September . Apologies for the inconvenience but I had committed to this event some time back. We will return to the regular scheduled live lectures (Mon, Wed) from next week.

    Please join the course Ed discussion forum for the course here - https://edstem.org/au/join/quFx6f We won't be using WebCMS forum.

    Labs commence in Week 2 . A self-study Lab that introduces you to the various networking tools to be used in the subsequent labs is available. We strongly encourage everybody to review it. This lab is NOT marked.
