Advanced Networking (ANET)

Last update: 14 Oct 2024




Welcome class of 2024/2025!

Welcome to the homepage of Advanded Networking (ANET), edition 2024/2025. ANET is a course for M.Sc. students at the University of Twente that enables you to understand, discuss, and evaluate advanced internetworking concepts, such as secure inter-domain routing, multi-path communication, path control, and experimental Internet architectures. ANET is a first quartile course (September through November).

The main audience of this site are students who enrolled for the 2024/2025 edition of ANET. However, it might also be of interest to potential future students and perhaps to fellow teachers around the globe who’d like to reuse parts of our format and/or content at their institution (or who’d like to provide feedback :-)

Students: please read this page carefully, so you know what we expect from you, and what you can expect from us. We’ll provide a summary at the ANET introduction lecture on Fri Sep 6, 2024. More details are in the draft schedule below and through TimeEdit.

The section Additional Reading points to papers and reports on advanced networking concepts that we won’t discuss in class, but that we think are nontheless very interesting. Feel free to check them out and discuss them with us if you want.

Goal of this site

The goal of this webpage is to provide you with a one-stop shop for everything you need to know about ANET. It focuses on more static information, such as the course schedule, evaluation criteria, and learning goals. Please check the UT’s teaching services for more dynamic information, such as TimeEdit for information on lecture hours and lecture rooms and Canvas for the ANET message board. Canvas is also the official archive for uploading your blog and P4 code, which are 2 of your deliverables for ANET (more details below).

We use a separate public website because we’d like to share ANET’s format with other universities and students so they can potentially learn from it. Also, ANET is a collaboration with SIDN Labs, the research team of the .nl operator. They are proud of contributing to courses like ANET and would like to underscore the importance of companies helping to educate the next generation of engineers and researchers, such as in the area of advanced networking concepts. Finally, the UT is a public institution, which we believe means it should share its education design and material with the Dutch society and beyond as much as possible.

Prerequisites

Before taking ANET, you must have successfully passed an introductory course in computer networks, such as the bachelor module Network Systems (202001026). It is your responsibilty to assess if you have the required background knowledge for the course. This is also why we highly recommend scanning the ANET papers before you enroll.

Please contact the course coordinator or your Study Advisor if you have any questions regarding prerequisites.

Enrollment

You can only sign up for ANET through OSIRIS. We do not accept registrations via email or other channels.

We urge you to scan ANET’s list of papers before you sign up, so you know what to expect. Should you end up unsubscribing from ANET, then please unregister through OSIRIS. In this case, we appreciate it if you share your feedback as to why you unregistered with the ANET coordinator (email above) so we can use it to further improve the course.

ANET is a highly interactive course in which you study research papers on advanced networking concepts, engage in technical discussions with your peers (“group-based learning”), and present a paper you studied in depth. The number of seats is limited to 16 because we ask every student to present a paper and we can only fit two presentations in one lecture.

We admit people on a first-come-first-served basis using the OSIRIS timestamp of your registration. We’ll put you on a waiting list if more than 16 students sign up and let you know if a seat becomes available.

Topics covered

ANET is an overview course (see Background). This means that ANET lectures will introduce you to a wide range of inter-domain networking topics [Shosh], such as programmable networks, routing security, and alternative Internet designs.

We picked the topics for ANET “going up the stack”: from programmable networks (the hardware), to BGP security (routing and addressing), DNS security and privacy (naming), transport-level protocols (QUIC and multi-path communication), a specific networking application (data centers), and Internet architectures (a broad view on inter-domain neworking). The other reason for selecting these topics is that your teachers are conducting research in these areas, which means they can tell you everything about it (and of course we love to talk about our work we do :-)

Teaching material: academic papers

We use academic papers and an occasional Request for Comments (RFC) as our teaching material. We selected papers that help you understand generic network architectures and principles for a particular topic that are still relevant today, such as the design goals of the Internet and the mechanisms that aim to secure the routing system. As a result, the ANET papers are “milestone” papers that may be quite old, with one paper going back to the Internet’s proverbial “stone age” (1995).

The references (between square brackets “[..]”) point to the papers at the bottom of this page.

Lectures

The goal of the lectures is to able you to learn from each other and from your teachers and to test your understanding of the topic of the lecture. ANET consists of a total of eight lectures, each of which focuses on one specific topic and covers three papers: an introductory paper and two advanced papers.

An introductory paper gives you a basic understanding of the topic of the lecture, such as inter-domain routing security. We test your understanding of an introductory paper through a closed book, individual multiple-choice test that you will need to make in class. You’ll make the same test again in a group with 2-3 of your fellow students, enabling you to learn from your peers by discussing the questions of the test with them. So, in total you’ll need to make 8 individual tests and 8 group tests.

An advanced paper explores the topic of the lecture in more depth. We test your understanding of one of these advanced papers by asking you to write a review about it in the form of a blog and present it in class. We’ll publish the best blog on the ANET website, of course with the author’s explicit consent. We won’t publish the other blogs. Please check the Assessment section and the section deliverable #2 (blog) for more on details on writing the blog.

NOTE WELL: You must attend all lectures because that’s when the tests take place. Also, ANET is an interactive course which depends on eveyone actively participating in the discussions, for instance in the Q&A after each talk.

P4 sessions

As part of ANET, you will get a first practical experience with programmable networks using the P4 programming language (see “Deliverable #4: P4 lab assignment” below). You will not need to study P4 in-depth.

We provide three P4 sessions: an introduction to P4 and two half-day P4 lab sessions. The lab sessions enable you to ask questions about the P4 excersises and have them signed off by the Teachin Assistant. They also enable you to allocate two large chuncks of time to the P4 excersises. However, we strongly advice you also work on the P4 work at home and not just at the lab sessions.

Guest lectures

In addition to the regular lectures, we also offer two guest lectures. Their goal is to give you a flavor of operational network infrastructure (current and experimental) at companies and of ongoing research in one of the areas we address in ANET (e.g., routing).

The guest lectures are open to everyone (ANET students, other students, and university staff).

Guest lecture : Access Networks

Title: Technologies to Improve and Increase the User Experience in Access Networks

Abstract: Private Networks are becoming increasingly complex. ISPs are expected to help end users quickly and adequately. This is increasingly happening in a multi vendor environment. How do you monitor the whole and how do you set things up for the user? Topics covered include BBF TR-69, TR-369 and TR-181 as well as Wi-Fi management and a future with AI

Lecturer: Eric van Uden, AVM ICT GmbH

Guest lecture : To be announced

Title: The anatomy of an ISP/NREN network

Abstract: SURF is the national research and education network of the Netherlands. This presentation will take you through the entire “stack” of the SURF network. From 11.000km of ground fiber up to service delivery through automation & orchestration. I will discuss optical technologies used up to how the network services are actually delivered to our member institutes.

Lecturer: Max Mudde, SURF

Deliverables

Your deliverables for ANET are:

Assessment

We asses to what extent you attained ANET’s learning outcomes (see Background) based on academic papers and RFCs you will need to study and a lab assignment you will need to carry out.

To pass ANET, your overall score will need to be 5.5 or higher, which we calculate as follows:

((average score of your 8 individual tests)*25% + (average score of your 8 group tests)*25% + (score of your blog)*40% + (score of your presentation)*10%) * (score of your lab assignment)

The scores of the tests, blog, and presentation are between 1 (worst) and 10 (best). The score of the lab assignment is either 1 (pass) or 0 (fail).

There are more details on how we grade each of your deliverables (group tests, blog, presentation, and lab assignment) in the sections below.

Deliverable #1: eight multiple choice tests

Each ANET lecture involves a multiple-choice test to assess your understanding of the introductory paper on the topic that we discuss in a particular lecture (see Schedule). The test is closed book and you will need to make it in class, first individually and then the same test in a group with 2-3 of your fellow students.

The goal of the group-based test is to enable you to learn from your peers and further increase your understanding of the paper. The group-based test also has one open question in which we ask you to formulate the main takeway of the paper in one sentence of at most 25 words.

We calculate your grade for a particular test as follows:

Grade of individual part of the test = maximum of
     ((S-G)/(Q-G))*9+1
and
     1

Where S is the number of answers you got right, Q is the number of questions in the test, and G is the “guessing factor”. The latter is the number of answers you could have guessed correctly if you hadn’t read the paper, which is usually Q/4 (most tests have 4 answers you can choose from).

The open question of the group-based tests will get you one point, which means that we grade those tests as follows:

Grade of group-based part of the test = maximum of
     ((S-G)/(Q-G))*8+O+1
and
     1

Where O is 1 if you got the open question right and 0 if you didn’t.

Deliverable #2: blog

Your second deliverable is a blog in which you review one of the advanced papers in your own words. The goal of your blog is to enable readers to assess if they’d like to read the full paper based on your review.

Instructions for your blog

You can use at most 1.500 words.

Make sure your blog is self-contained, which means that folks who haven’t read the paper should be able to understand it without having to consult other documents. Your target audience are readers with a background in computer networking, so you don’t need to explain basic networking concepts.

Your blog must begin with a section in which you explain the paper’s three main takeways in at most 150 words. The “Key Insights” box on page 1 of paper [SCION] has an example that might provide inspiration.

At the end of your blog, briefly reflect on the process you followed to write the blog in at most 100 words. For example, how did you go about studying the paper and understanding its contents, and how did you write the blog. Please also indicate how you incorporated the feedback you received at your presentation. The reflection does not add to the word count of your blog.

Examples of topics you can discuss in your blog

The topics you discuss in the blog should capture the core of what the paper is about. Table 3 lists a few examples of topics you can discuss in your blog.

Table 3. Example topics to blog about.
Design paper (e.g., [SCION]) Measurement paper (e.g., [DNS-SP])
What is the problem that the authors aim to solve? What is the problem that the authors aim to solve?
What requirements do the authors articulate for their work? What methodology and experimental setup do the authors use?
What does the high-level design and operation of their proposed system look like? What are their key findings and conclusions?
How does the design address the requirements? How do they propose others use their measurement study?
What are the pros and cons of the authors’ work and why? What are the pros and cons of the authors’ work and why?
What would you do differently? What would you do differently?
Would you recommend the paper to interested readers? Would you recommend the paper to interested readers?

Use of ChatGPT and other tools

You may use ChaptGPT, Grammarly or other tools to help you improve the language of your blog. The original content MUST however be written by you.

You must include this statement in your blog if you used ChatGPT or other tools:

“AUTHOR DECLARATION: During the preparation of this work, I used [NAME TOOL/SERVICE] ONLY to improve the language of my blog. I confirm that I alone wrote the original text in full and that I then reviewed and edited the content using [NAME TOOL/SERVICE]. I take full responsibility for the content of the work.”

If you did not use such tools, then include a statement that no AI was used:

“AUTHOR DECLARATION: I did not use any artificial intelligence tools to write my blog.”

Your blog MUST include either of these two statements or otherwise we will not take it into consideration.

The above statements are based on the UT’s policy on the use of AI in education, adapted for the specific case of ANET.

As per the same policy, we will consider suspicion of unpermitted or unreported use of AI as potential acadmic misconduct. We will report such cases to the Examination Board and they may result in you having to take an oral exam on your blog, amongst others.

Tips on how to write a blog

We recommend you check out a few of these sites on how to write a blog:

Another source of inspiration may be prof. Aiko Pras’ guide on how to write a scientific paper. That’s different from a blog, but the video might help you structuring your blog anyway.

Referencing, citing, and quoting

If you want to literally include text from the paper (or other sources) in your blog, then you need to reference and quote it. This includes sources where you are an author. During the first lecture, we will briefly discuss the differences between citing, quoting, and copying (see slide of 19 of this presentation).

If you want, you can use references in your blog rather than hyperlinks to refer to external sources. We’ll exclude them from the wordcount, and we also won’t count the blog’s title and figure and table headings.

You can reuse graphs from the paper if you want, but make sure clearly indicate that they’re from the paper and not your own.

Note that Canvas will automatically check your blog for plagiarism when you submit it. As per the university’s policy, no forms of plagiarism are tolerated.

Please contact us if you have questions regarding citing and quoting.

Publication of the best blog

We’ll publish the blog with the highest grade on the ANET site after the course, so other students you can learn from your work (and you can show it off to your friends :-)

Of course, we’ll only publish the blog with the author’s explicit consent.

Evaluation criteria

We will evaluate your blog based on the following criteria:

Grading process

The ANET teacher who gives a particular lecture will evaluate the blogs about the papers of that lecture. In addition, one of the other teachers will review your blog for a cross-check. They both use the evaluation criteria listed above to grade your blog.

We’ll be evaluating all of your blogs in one go at the end of the course. This means that you’ll get your grade around two weeks after the last presentation. That’s because that person has 1 week to submit their blog and we’ll need a few days to evaluate your work.

The reason for reviewing and evaluating all blogs in one go is that this approach will allow for a fairer assessment because we have the overview of all blogs, plus that it’s more efficient on our part.

Deliverable #3: presentation

You’ll need to present the paper that you wrote a blog about to your peers in at most 15 minutes, consisting of 10 minutes of speaking time and 5 minutes of questions and discussion.

Your presentation must start with your three main takeaways of the paper.

Your lecturers will score your presentation based on clarity, structure, and how well you responded to questions. Your fellow students will do the same through a feedback form that we’ll hand out at the beginning of each lecture. Your lecturers will use this feedback to round off scores. You must return the feedback forms before leaving the room.

Here’s a few How To’s for giving a talk:

Deliverable #4: P4 lab assignment

The lab assignment involves you programming the packet handling functions of a (simulated) open programmable router using the domain-specific language P4 [P4a], which we believe is an important enabler for an open programmable Internet infrastructure [RI].

The goal of the P4 assignment is to for you to get a first practical experience with programmable networks. Its goal is not to give you an in-depth understanding of programmable networks, which would require a separate course.

We will discuss P4 in one of the first lectures and we’ll provide detailed information on the lab assignment through an introductory lecture (see Schedule). The Teaching Assistant is available for questions.

You will need to carry out the P4 assignment individually at one of the two lab sessions or at home. When you’re done, you need to show your results to the Teaching Assistant in one of two lab sessions (see Schedule).

The teaching assistant will sign off your P4 assignments if:

The P4 repository we’ll be using in ANET is here: https://gitlab.utwente.nl/m7717102/p4-labs-2024

We strongly advice that you also work on the P4 lab assignment at home and not only at the lab sessions (see Schedule). That’s because it might take some of you more than the two lab sessions to finish the work. Also keep in mind that the Teaching Assistant needs to help multiple students at the lab sessions, so the person might not always be immediately available for you.

A few P4 tutorials that you might find useful are:

Submission of deliverables through Canvas

Please submit your blog, presentation, and P4 code through Canvas (unzipped) so we can confirm that you yourself carried out the work (SimCheck).

You do not need to submit the multiple-choice tests through Canvas because we’ll get them from you in class.

Resits

In some cases, you can take a resit for ANET’s in-class test or blog, such as when you missed a lecture because you were ill. Please check with the course coordinator if you think this applies to you.

We offer resits as follows:

Survey

At the end of the course, the university’s Quality Assurance department will send each of you an online survey to ask how you experienced ANET and how you think we could further improve it. We kindly request a few minutes of your time to fill it out so we can learn from your feedback and further improve ANET next year. Your fellow students who will take ANET next year will thank you for it!

At the beginning of the course, we’ll inform you what changes we made based on the feedback we received from last year’s students. (We’ll inform them those changes as well, so they know what we did with their feedback.)

ANET papers and RFCs

We use a total of 24 papers and Request for Comments (RFCs) for ANET. Please check the Lectures section on why we picked these papers and how they interrelate.

Background

Learning Outcomes

After successful completion of the course Advanced Networking (ANET) you will be able to:

We emphasize that ANET is an overview course, which means that you’ll be “scratching the surface” of a range of topics. This also goes for the P4 assignment, which will give you a first practical experience with programmable networks but not in-dept.

ANET also enhances your research skills, because you will need to independently review, analyze, summarize, and present research papers.

Motivation

The problem that the Internet originally aimed to solve in the 1970s was how to enable university researchers to share expensive computer hardware via a network, which later evolved into how to make computer networking ubiquitously available for everyone [CYCLE]. The relatively simple design of the Internet’s core protocols (TCP/IP, BGP, and the DNS) solved both problems beyond imagination, with the Internet now being critical for almost every aspect of our everyday life and for our society.

However, the success of the Internet also introduces new problems, because it doesn’t always meet modern requirements such as society’s need for increased security, resilience, and digital autonomy [RI] and applications needing new network functions, such as control over and verification of network paths [SCION] and low-latency data transfer [CYCLE] (e.g., real-time trading or controlling swarms of autonomous objects such as robots and cars). Researchers and engineers have therefore developed and deployed various extensions of the Internet’s core architecture, such as a network inspection plane [RI], routing security [BGP1] [BGP2] and multi-path communications [MTCP1] [MTCP2]. Others are proposing and experimenting with completely new types of inter-domain networks, for instance to support programmable and reusable protocol functions [TROTS] [RINA1] [RINA2] or different communications paradigms (e.g., content-centric instead of host-centric communications [NDN]).

We offer ANET because we expect that some of these Internet extensions and new types of internet infrastructures will have an impact on deployed network infrastructure in the next few years, for instance because of the widely felt decline in digital autonomy in many societies and regions around the globe [RI]. An example is the BGP security extensions [BGP1] [BGP2], which network operators increasingly deploy (cf. certification-stats.ripe.net) to protect the Internet against routing hijacks. Another example are open programmable switches (e.g., Barefoot switches), which are already commercially available and enable engineers to define their own packet processing functions (e.g., for SCION or NDN traffic) in addition to IP on the same hardware.

Objective

The objective of ANET is to enable you to understand and evaluate advanced internetworking concepts, such as secure inter-domain routing, multi-path communication, and path control, both in the existing Internet as well as in alternative Internet designs (e.g., NDN, RINA, and SCION). This will give you a wider understanding of internetworking beyond IP-based communications.

From the university’s perspective, ANET helps preparing the next generation of researchers and engineers for future Internet developments, which is important to enable the Netherlands and Europe to stay in control of their Internet infrastructure.

Organization

ANET is a collaboration between the University of Twente and SIDN Labs (www.sidnlabs.nl), the research arm of the operator of the .nl top-level domain, SIDN. SIDN Labs’ goal is to increase the operational security and resilience of our society’s Internet infrastructure, for .nl and the Netherlands in particular.
