Mid-term Exam Details + Sample Exam + Poll on Programming Language + No lectures/labs in Week 6 Posted by Salil Kanhere Wednesday 16 March 2022, 10:25:14 AM. Marks for the first two labs and the answers are available. If you have questions about marking, contact your tutor. Their details are on the timetable page. The mid-term exam will be held during regular lecture hours (11:00 - 13:00) on Monday, 28th March (Week 7). Check the information available on the Mid-term Exam page (includes information about the content covered, exclusions, online meeting information, etc). A short video is also available in the Youtube and Echo360 playlists and on the mid-term page (with slides). The link for the exam will be circulated towards the end of next week and will also be available on the Mid-term page and on the course Moodle page. A practice exam is available here: Moodle link . The exam uses the Inspera platform which will be used for both exams in this course. You can only attempt the exam once so make sure you 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 provided answers and compare them with your answers. Everyone is strongly urged to attempt the exam. It will familiarise you with the Inspera assessment environment so that there are no surprises on the exam day. A PDF file with the exam questions and answers is posted on the mid-term exam page. 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 link . 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 started on the assignment. See you online during the lecture tomorrow where we will wrap up our discussion on TCP and the transport layer. Week 5: Exploring TCP and Congestion Control, Tutorial (No lab), Mid-term Exam coming up, Assignment is out Posted by Salil Kanhere Friday 11 March 2022, 12:14:10 PM. This is a busy week with a lot of updates, so make sure to read through this list multiple times: Lab 3 is due by 10 am Tuesday, 15th March. There will be a tutorial replacing the lab (in your usual Zoom/Teams meeting) next week. It is not marked. This will serve as useful practice for the mid-term exam. Please look through the questions beforehand and try to solve them by yourself. ALL questions are from past exams, so effectively it is a sample (but longer) exam paper. You can ask your tutor to prioritise questions that were particularly difficult for you. The question set is released. In the lectures, we will explore TCP in detail followed by a discussion on congestion control. Slides are available. The mid-term exam will be held during regular lecture hours (11:00 - 13:00) on Monday, 28th March (Week 7). Further information about the format and a sample exam will be available middle of next week. The exam makes up 20% of your final mark. Lab 2 marks and solutions will be available early next week. If you have questions about your marks, please connect with your tutor. The programming assignment specification was released earlier this week. We have released two videos - the first one covers the assignment spec and is available in the regular lecture feeds (Youtube/Echo360) and is also linked from the assignment page. The second video covers the basics of multi-threading and is linked from the assignment page. You are strongly encouraged to watch both videos. The slides for both videos are on the assignment page and so are sample code fragments for multi-threading which you may use in your code. Assignment consults will run from Week 7-10. Details will follow. The deadline for choosing the non-CSE option is 5 pm, 18th March. Only students who are not enrolled in a CSE program are eligible. Further details are in the specification. Requests after the deadline will not be entertained. Everyone is encouraged to discuss the homework questions on the Ed discussion forum. All of these questions are from past exams. We have provided answers and comments on these discussions. You are welcome to provide anonymous feedback about the course through the following link . Flexibility Week ( Week 6, 21-25 March ) is close. There will be no lectures or labs in that week which will give you an opportunity to catch up and prepare for the mid-term exam and get going with the assignment. The census date for Term 3 is 13th March . While we do not encourage it, this is the last day that you can drop the course without incurring fees. Have a good weekend and see you all in the lectures next week or on the Ed forum. Signing out. Assignment Specification Released Posted by Salil Kanhere Monday 07 March 2022, 09:12:14 PM.

The Lab 1 report is due by 10 am Tuesday, 1st March . Submission instructions are in the lab spec. Submissions received via email will NOT be entertained. Do also note the requirement to submit a TAR (NOT ZIP) 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 (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 personal computer (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 the Ed forum. We are happy to provide feedback on your attempts. This should serve as excellent practice for the exams.
