Lack of autograder with instant feedback is a major downfall. Could be better. Lectures are interesting, but the assignments not so much. I wish some of the topics were covered better. 80 points (very good from any point of view) CS 6250 Project 7 - Firewall GUI Client/Server CS 6250 - Project 7 required manually loading a server files for testing TCP and UDP ports. Quizzes were challenging I never got them all right on the first try, but with the multiple attempts allowed and a reasonable testing strategy, I was able to get them all correct. The videos are pretty straight forward, and you have to know videos and papers for the TESTS. I definitely learned a lot in this course. As if Wikipedia is the fountain of knowledge!! I was very neutral to disappointed on the (3) exams. These people arent going to make it in courses like ML, where everything is vague. But in general, i didnt like the material of the course and i feel that i didnt benefit much fromt the course. The TAs made effort for the first half of the course, but by the end, most Piazza questions about the material went unanswered even the ones asking for guidance on errors in the test prep materials. Most students collaborated on reviews before the exams. Having more TAs doesnt necessarily solve all issues that arise from such a large class in a variation on the maxim of the mythical man-month. The undergraduate networking course required implementations in C, and those projects were much more time-consuming then anything found here. Obscure! Quick to respond to issues and were very active on Piazza. Even the projects though were fraught: the instructors had to make the last project optional since so many people werent able to understand it/make it run on their virtual machines. Instructor is VERY active on Piazza - really nice! There was something due nearly every week, with projects of varying difficulty and with tests definitely requiring a good amount of time to study, as they included a lot of short essay questions, were timed, and proctored (via ProctorTrack). A little too easy. Youre good to take the quiz after reading the lecture material. Overall, if you dont know much about computer networks going into this, youll come out with a much better understanding assuming you put in the work. The course lectures are mostly text based, with some video lessons sprinkled throughout. The professor seems to be very aloof, and the course is entirely ran by teaching assisants who are not very attentive on the forum. I would also recommend brushing up on some of the networking fundamentals, but thats not strictly necessary. I only had a couple of direct interactions with the TAs and my questions were quickly resolved. However they claim that they cannot change a single video segment or annotate it because it is easier to redevelop the entire course than it is to change one bit of it. Dr. Kontes accent is not much of a barrier, but she appears to be very nervous in front of a camera, leading to a bit of monotone. The Jupyter notebook environment is also unstable. Project 6: BGP Measurements (Difficult new project; time-consuming). Subsequent assignments were way easier. With some exceptions, Piazza discussions were not great and TA responses were often no more than a couple of words. I spent ~5-10 hours on each of the courses 7 two-week assignments. The course is revamped from Summer 2015 with new professors, and it has become bit difficult course (not very easy anymore as in the previous semesters). The lectures are good because they cover an interesting range of topics (a broader range than other networking classes Ive seen). Most of the topics are interesting, the projects are really captivating IMO, but the readings are pretty boring. For background, tasks 1, 2, 3, and 4 are loosely related but not dependent on each other. If you want to learn Computer Networks, I feel like it would be more interesting and faster to just pick a random Coursera course or read the textbook (Computer Networking by Kurose and Ross). Highly recommend. I was surprised at the number of people complaining about this project. Most of the students including myself posted just for the sake of it and didnt contribute to learning. Do the mininet and OpenFlow and Pyretic tutorials on each projects website and understand what these technologies are doing, ahead of when it comes up in the course. Exams are based only on the lesson content. Many research papers to read. =======Class experience======= Each project is very easy if you have decent programming experience in Python or a similar language. Slack channel was lively and everyone helped each other both on Slack and EdStem without violating the academic integrity guidelines. Nope! Theyre not very difficult. The TAs were absolutely incredible, particularly Erick. Now this semester the class had to go through some issues. For instance, FANG companies have hundreds of hybrid engineers who have a mixture of networking and software skillsets to support their global infrastructures. If I was more curious about something, I would reference the book or whitepapers (which I did frequently). I also stopped watching them after the first few. Lets start with the course material if you took an undergrad CN course like I did, this is pretty much a refresher on that with a few more interesting details sprinkled on top. I also have a strong interest in security and so I really enjoyed that security was an ever-present topic in the course. On the rare occasion the TAs were able to reach the prof, she made more false promises about when shed show up. Standard lectures, content itself isnt terribly hard to follow. So 12% extra grade was just ridiculous and made the class too easy to get an A. For a University with the reputation of Ga Tech, it strains credulity that were stuck with this tech. All of the problems from this semester stem from a lack of leadership. All the lectures and assignments should be thrown away and the course redesigned from scratch. Nope. This class is NOT easy by any stretch of the imagination. The course assumes an understanding of networking fundamentals, so recommend brushing up on that if you dont have this background. Tests are not worth much so its really just doing well in the labs and decent enough on exams. I find this claim ridiculous at best. Overall, not a bad course but not really worth the time. Any computer that can play minesweeper can take this course If you can average a high C in the exams (easily doable) and got full marks on all your projects, youll walk out with a good amount of knowledge gained and an A. Ok class, pretty easy material. Overall a bad impression from the quality of the lectures. Professor Konte and all TAs were really helpful throughout the course! I did not really study extensively for exam 1 and still scored an 83%. So there was a bit of a learning curve when it came to Python, which accounts for why I marked this as a hard course and accounts for extra time spent researching data structures in Python. You should think about whether you REALLY want to learn networking or not. I majored in math in undergrad, so I actually didnt know much about networking before. Book was somewhat helpful but not entirely relevant. Homeworks were good and the professor provided good answers, Office Hours were good and often provided hints and good discussion on homeworks and tests, Tests were tricky and required a lot of time to complete. Whether you are brand new to or a long-time user this session will get you up to speed on putting the latest features by the PowerShell team into action to solve the challenges you face today in operations. First off - the lectures are awful, as everyone else says. Its optional, but I learned a lot more from it than the lectures, so if you dont have a networking background I highly recommend it. Most of the projects require 2-3 days of work and are not hard at all. I had taken IOS in a previous semester. In addition to the biweekly assignment frenzy, there are also weekly quizzes. There were 7; Im told there are fewer in the Summer. I cannot even call them proper lectures. This clas is easy in some way, but very difficult in others. I feel hes truly altruistic and I wouldnt be able to be like him. Project #5 (BGP Measurements): A project that requires you to extract data contained within rib/update files to compute descriptive statistics and/or generate data visualizations. Over 70% of the class got As, so the course could probably be a little harder, but as long as everyones learning, I dont really see the problem. If youre a solid programmer, this is a good first course to take. I learned a lot, even having professional experience. Reading the previous reviews, I was given the impression that this course would be easy, similar to Software Architecture and Design, and guess what? For the Python skills you can take Udacitys Intro to Algorithms course which I had gone through only about a third of its material but it was enough for me to be able to successfully complete the projects that required a better Python understanding. I took this course, because this review site listed it as an easy course. I did have a couple issues with questions on the exam that boiled to X is a type of _____. Where the answer to this question was one offhand sentence in a lecture. The actual coding required to implement the project requirements is not bad at all, but mandates competency with Python data structures and the pybgpstream/matplotlib libraries. I typically spent the first week watching lectures/reading papers, 2-3 days exploring the provided code and typing up my solution, 1 day coding, and 1 day debugging. There were weeks when I literally didnt have to touch the class. So be conservative. The assignments were mixed. Low stress on projects, Cons: The VM can be difficult to use/debug when things go wrong, it felt very brittle. Personally, I found the BGPM and the Openflow projects hard. You might need to re-watch or re-read in order to really get an understanding. I thought Prof Kontes lectures were great and the TAs are quick to answer questions in EdStem and Slack. Its important to note that I dont have a traditional CS background, and before this class had not spent a ton of time in Python. But the actual course? Responsive on slack, open to criticism on exams, plenty of office hours, willing to go in whatever direction the discussions wanted to go. There are 8 projects and 3 exams. I feel lucky we had some talkative classmates. It allowed me to learn the basics of python, to get familiar with Linux and to ease into the rhythm of studying every day without it being too stressful. This class can teach beginners a fair amount without unnecessary pain. The result is vaguely worded tests, disappointing grades that are curved down, and core material that is still easy. Projects are 66% of your grade. If youre stuck, make sure to attend office hours and check out the TAs introductions/explanations. Even with my poor test scores, my final grade so far is in the high 90s because Ive gotten full points on the projects so far. With just a few exceptions the timeliness of grading and responses on Piazza was top notch. I vastly under-estimated the robustness of my code on this and it cost me. Thats not what this course does. Courses taken so far were: Classes taken concurrently with this class: It is somewhat easy class that could be taken along with a more difficult class. ShenweiLight of Taihu Lake, =======Liver======= I know that this class has been reformatted quite a bit. Towards the end I think there were some heavy modifications to semesters previous, and the details had not yet been fully worked out. Overall, I was happy with the course. Tests comprise 30% of the total grade. The structure is random, the slides lead you down a path, throwing vaguely worded concepts at you left and right until youre completely lost and unsure how everything fits together. The study guides provided by the TAs are very helpful. No autograder, though But the TAs seem to be very lenient about grading the projects. The projects werent very difficult however they did take some time to understand. Tests and projects were generally graded within a couple weeks. project hours were variable, but overall 5 10 hours depending on the project. It is not an easy course and its difficulty is medium. Sounds obvious, right? This is the first course I completed, and I think despite the fact Summer term is always challenging, someone truly focused can get an A. Its an easy A without some preparation of course. They were all high quality papers and they all covered very interesting topics: I found most of the projects very interesting as well, though I didnt like the report based ones which were pretty boring. The asignments are easy but frustrating. But instead, it gets burned due to administrative issues. Overall I found this was a good class, but since it was my first OMSCS I have no other class to compare it. The TAs favorite saying was, Im still waiting to hear back from the professor. The tests (only 3 of them) were a little more difficult than I thought, but were fair and covered the material well. In that case, these lectures will serve you well, as topics are presented in their raw state, technical jargon and all. More of the former though. The instructors were great, the TAs were great. I felt like I was being penalized not because of my understanding, but because of some weird artificial limitation. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Its an appropriate foundational class, anyone who aspires to a Masters in CS should understand and be conversant in these concepts. There were three, and only the first seemed to do a good job asking interesting questions that required advanced thinking about the concepts; the other two were filled mostly with what seemed like arbitrary tidbits from the readings and lectures, and were sometimes ambiguously worded. RPs are dry and boring. The 2nd and 3rd assignments were the most challenging of the 8. Crickets. Probably the hardest part of the course was learning Python which I had no knowledge of beforehand. The lectures are relatively well donethey provide a lot of good information, and they have both video and text. the instructor reading a paraphrased excerpt of the text, a paraphrased digest of content from the book or a research paper. Even though I did labs on Bellman-Ford and MST, it felt like most of the effort was understanding the project code and not so much the underlying algorithms. The SDN project took about 7-8 hours. However, when I study for the tests or have to do assignments, I actually find the things being taught interesting, but like I said, the lecturer ruined it. Quizzes can be sort of easy sometimes (search and find solution), while other times require some thought, but still are centered around just making sure you did the reading - there is a quiz for every week there is a reading. Unfortunately, we spent more time debating the quiz & assignmenting file-naming conventions than actually discussing the content of the course. After scrambling on SDN, I started this one the day it came out and I was alright. I suggest just reading the textbook instead. Both basic and research topics in networking are covered. I was quite disappointed in this course. They said it was because of the grading scripts. The most complex code youll write is a loop. The assignments are hard (the first assignment was an exception, rest were very hard). sh?). The project was changed after it was released, we lost 2 days and they gave us 2 extra days. This course has good TAs, but is very, very dry. Tests: With the 5% from project 7, you have up to 6% extra credit possible in the class. I worked much longer than most people, at least longer than they say they do. Yes I wanted an easy class, but I wouldve preferred the topics to be more in depth. The questions often seemed difficult to answer by just using what was presented in the lectures, pulling from the optional textbook which I did not opt to purchase, and sometimes just contradicting what was said in lectures. Because it was the summer, they squished the latter half of the content into a single exam worth 30% of your grade. The class felt very disorganized and the teacher only showed up twice during the semester, so youre taught exclusively by TAs. This was a relatively low-stress class. not sure, Overall not a bad course if you want to learn about networking. I found the projects to be quite straight forward but at the same time a good learning experience. This was an OK class, but it could have been better. I personally chose this course because I was going to have a busy few months during this semester so I needed a course that was manageable given the time limitation. Too much handholding for a grad level course on the first couple projects even though they arent worth much weight. The projects are pretty easy. The lectures were actually pretty good throughout the first half of the course but became more technical and less well explained during the second. The simulation was done in c++ because we encountered some errors while working with python and DPI. For all of the students who are struggling. There are several extra credits opportunities were offered. Lectures are unintelligible, archaic, and uninspiring. The projects were easy for the most part but Project 2 was pretty difficult. Just open-book quizzes and programming assignments. Overall, the course is far too easy on its own, but the material itself is very interesting and if you dig a little deeper and do some extra work on your own, you can still get just as much out of it as you get out of the more stand-alone challenging courses. PRO: Fairly straightforward course but low quality. For the projects that required some amount of programming, there are students that have shared test harnesses that helped validate that outputs are matching whats expected. The tests cover a lot of material and the questions are fairly subjective overall. I wouldnt let that (not having a traditional CS background) scare you off entirely if youre willing to spend a little bit of extra time focusing on Python (which I think was well worth it, and combined with an interesting course and great TAs, makes this course great). Theres the odd question or 2 that feel tricky and difficult, but for the most part the answers correspond directly to the notes provided. However, addressing the problems related to lectures, the SDN/BGP Measurements projects, and Dr. Kontes presence in the class would go a long way in improving this classs quality. Its a great course that helps refresh basic networking concepts and introduces you to software defined networking. Projects: Not much assistance was offered, and if you got stuck on a coding issue, not much help was available (except from Piazza, see above) Serious growing pains right now in this class - large size and no professor present. The TAs and Professor Konte were really helpful. There was even some bug in a given code and we had a hard time to get a result which we expected from the material. Lets start from the positive thing first. Shows that its indeed difficult and requires a lot of effort. I like the lectures. This isnt an introductory networking course, rather it surveys a variety of topics being used in todays internet and how they contribute to how the internet works as a whole. I like the pace of this course. There are 2 closed-book proctored tests involving a plethora of multiple choice, descriptive-types, and problem-types questions. If yes, it was easy. She publicly castigated / punished students she apparently considered to be overly creative / curious, or insufficiently enamored of her top-down approach, on a number of occasions (as she seems to conflate them with the lazy or unmotivated as being problem students.) Id recommend this as a first course given the great amount of help and active participation on Piazza(especially by the Head TA Stacia). The quizzes were often worded in ways that made them more difficult than they should have been. We had 7 projects in the course. Projects - Course was easy up until the final project, which took more code and more time to program than the other 3 projects combined. The tests did not cover anything that wasnt in the lectures/homework/papers, but they covered a vast amount of content. The other TAs were quick to respond and grade the assignments/tests. I do wonder what the opportunity cost is though. The projects didnt require much understanding, and there were no exams. Quizzes can have a *gotcha answer in there. Material is great and so were the projects. I did find it interesting, but I cant argue that it needs some polishing. TAs were supportive, but did not really encourage creativity. Most lectures are just text pages to read through or the instructor reading the same write-up from a script in a monotone voice. Each of them requires that you have basic knowledge of Python 3. A small mistake in any of the project means that you lost A grade My suggestion will be that if you are looking for A - make sure that you spend those extra hours to iron out any issues. That sounds fine, but for 2 bad side-effects: So what this means is that instead of learning about the algorithm, we spent inordinate time on this constraint that well never see again. In advance of the quiz, they provide homework questions and answers. For context, I worked as a technical engineer for a SDN startup right after my bachelors, so I found all the projects to be easy, except the last one which wasnt really difficult but felt like it due to vague instructions. A little bit of my background, I am a software engineer with 3+ years of experience, studied Computer networks from an Electrical Engineering perspective before, but never took the CS one. This might be a negative for most though, depending on how you You will then be graded by some 20 year old TA that really doesny give a shit about any of this. This was great for me, since this was my first OMSCS course. It is important to start on the projects early and be active on Slack & Piazza. The remaining ones were fun and took probably 5-10 hours for each of varying difficulty. They probably have no programming experience as well but it does not change the fact that many projects are really not about the programming itself, all programming language uses in the course projects are basic. The topics are well formed. Tactically, there were 3 (none of them cumulative), all fewer than 30 questions. However, there was no change of redemption for the rest of the semester and my grades were reflective of that one error. Overall, projects are interesting, but should be improved in depth. Mininet is brittle and very twitchy, so you never know if the issues youre having are your own code, or the infrastructure. Projects are in python. Every week you did either an assignment or quiz. I took this as my first course and regretted the decision. If youve had no exposure to Python (like me), its a good way to get your feet wet. I hope my voice could get TA or our professor attention.
