COS-561: Advanced Computer Networks Princeton University Fall 2018 Princeton University's COS 561 is an advanced course offering a research survey on network protocols. Covering both classical internet protocols and recent research results, the course involves design, analysis, simulation, and measurement studies of protocols. Prior networking knowledge is beneficial. COS 561 provides a research survey on network protocols---the rules and conventions that communicating end-points follow to exchange data over a computer network. The course covers both classic papers about the Internet protocols and recent research results, and will consider protocol design and analysis, as well as simulation and measurement studies of new and existing protocols.  While the course has no formal prerequisites, some background in computer networking (e.g., COS 461 or the equivalent) is useful. See the [COS 461](http://www.cs.princeton.edu/courses/archive/spring18/cos461/) course for an overview of the material in COS 461. The course assignments will assume a basic familiarity with programming in languages like C, Python, or Go. 

COS-561: Advanced Computer Networks

A computer network is a collection of interconnected devices, such as computers, servers, routers, switches, and storage systems, that are connected together to share resources and exchange information. Common sub-topics include network protocols, congestion control, internet routing architecture, packet switching, etc.

CS 144: Introduction to Computer Networking Princeton University Fall 2021 Princeton University's CS 144 is an introductory course teaching core principles of computer networking, including packet switching, layering, encapsulation, and protocols. Students get hands-on experience in building parts of the internet infrastructure, like a router, and a reliable data delivery service. CS144 is an introductory course about computer networks. You will learn about the basic principles of computer networks, for example packet switching, layering, encapsulation and protocols; and you will learn how applications such as the world-wide-web, video streaming (e.g. Netflix and Hulu), video conferencing (e.g. Zoom and Skype) and BitTorrent use the network to communicate. You will spend quite a lot of time learning about the specifics of how the Internet works – which is of course by far the biggest computer network ever built. You will learn how applications communicate reliably over an unreliable Internet. And you will build portions of the Internet yourself! In fact, we believe that in CS144 you build more parts of the Internet infrastructure than in any other undergraduate networking class anywhere. It’s really fun to see how the individual pieces work: You build an Internet router, and a reliable data delivery service, and then you use it to communicate with remote servers.

In addition to lectures, we will also have a few in-class guest lectures by outside speakers. All the guest lecturers are excellent speakers with many years of experience making networks work at huge scale. We will also have one or more in-class exercises, which you will complete during the regular lecture time. These are designed to give you hands-on experience with tools that are useful for your labs.  The formal prerequisite for CS144 is CS110. CS144 is a lab course: 45% of your grade is based on a quarter-long lab assignment implemented in C++, which means you need to be very comfortable with C++ and using standard debugging tools (if you are reading through thousands of lines of printf output you are doing something wrong). CS107 is not sufficient preparation: you need more programming experience. CS144 is offered every year, so please wait until you are ready before taking it. That being said, if you did pretty well in CS110 you should do fine in CS144. **Textbook**: The optional course textbook is: Kurose and Ross, *Computer Networking: A Top Down Approach*, 8th edition (7th edition is fine too). We will not be assigning readings, but it is an excellent reference to supplement the lectures and videos.

CS 168: Introduction to the Internet: Architecture and Protocols UC Berkeley Fall 2022 UC Berkeley's CS 168 is an undergraduate level course presenting a wide range of fundamental concepts related to the internet architecture and protocols. Students partake in several programming projects mostly in Python. Prior programming knowledge is expected.  This is an undergraduate level course covering the fundamental concepts of networking as embodied in the Internet. The course will cover a wide range of topics; see the lecture schedule for more details. While the class has a textbook, we will not follow its order of presentation but will instead use the text as a reference when covering each individual topic. The course will also have several projects that involve programming (mostly in Python).  Required: CS 61A, 61B, Math 53 or 54. Contrary to what the EECS department website says, CS 162 is not a prequisite.

You should know programming, data structures, and software engineering. In terms of mathematics, your algebra should be very solid, you need to know basic probability, and you should be comfortable with thinking abstractly. The TAs will spend very little time reviewing material that is not specific to networking. We assume that you either know the material covered in those courses or are willing to learn the material as necessary. We won’t cover any of this material in lecture. No textbook is required for this class, but we recommend [Computer Networking: A Top-Down Approach, 7th edition by Jim Kurose and Keith Ross](http://gaia.cs.umass.edu/kurose_ross/index.php) if you would like to dive deeper into the subject.

COS 461 Computer Networks Princeton University Spring 2023 Princeton University's COS 461 offers a comprehensive survey of computer networks, exploring principles from end-to-end principle to overlay networks. The course involves a study of classic to contemporary research papers and assumes prior knowledge of computer science. A survey of computer networks covering the end-to-end principle, multiplexing, virtualization, packet v. circuit switching, router design, network protocols, congestion control, internet routing architecture, network measurement, network management, and overlay networks. Survey of research papers from classic literature through contemporary research.  Students must have taken COS 217 and one of COS 316, COS 333, COS 318, COS 418, or COS 432 prior to enrolling in this course. Exceptions require explicit permission from the instructor. The assignments in this class are in Go, C, and Python. You do not need to have experience with all of these languages before taking the course. However, you should be comfortable with learning new programming languages and finding resources on your own, independently as you attack problems. You will be exposed to new programming languages and environments. ### Class Materials

CS 249i The Modern Internet Stanford University Winter 2022–2023 Stanford University's CS 249i is an advanced networking course focusing on modern Internet topology, routing practices, and recent network protocols. The course covers pressing privacy, security, and abuse challenges, with a mix of lectures, guest talks, and practical projects. CS249i is an advanced networking course that covers how the Internet has evolved and operates today. Topics include modern Internet topology and routing practices, recently introduced network protocols, popular content delivery strategies, and pressing privacy, security, and abuse challenges. The course consists of a mixture of lectures, guest talks, and investigative projects where students analyze how the Internet operates in practice.  This course assumes a basic understanding of networking, including protocols like Ethernet, IP, and TCP, as well as routing concepts and socket programming. This is not an introductory networking course and students should first take Stanford [CS 144](https://cs144.stanford.edu), EE 284, or equivalent. For a refresher, consider "Computer Networking: A Top-Down Approach" by J. Kurose and K. Ross or "Computer Networks: A Systems Approach" by L. Peterson and B. Davie. Projects will be implemented in [Go](https://golang.org/).
