Research areas: mobile networks, mobile systems, wireless networks, network security
Independent study (on mobile systems or networking on Android phones) is welcome!
So let me introduce myself. My name is XXX,
PhD in UCLA (last summer)
So, you see, I am quite new to OSU. Actually, this is my first official lecture in OSU.
So I may not I may not be able to immediately answer all the questions you have, esp those regarding to the department/campus policy or schedule conflict issues.
But please feel free to ask and I promise that if I don’t know that, I will find the right person and get back to you ASAP.
My research interests mainly cover mobile networking (3G/4G and wifi), and mobile system and security.
This is my address. This is my most preferable contact approach.
My office
We have two hour office hours every week in my office. If you can’t make it during these hours, please send me an to make an appointment.

tips
(1) Add [CSE3461] in the subject;
(2) send homework/lab questions to grader (cc to me); send other questions to me;
Course webpage
Carmen (assignment, lectures, all course materials)
(for first 2 weeks)
We have two sessions. But I strongly encourage you to stick to the one.
(several reasons: schedule will be slightly different, your team member and classmates in the same room;;
Last but not the least, the class is full. )

Course Information
Textbook:
J. Kurose & Keith Ross, “Computer Networking: A Top Down Approach,” 6th edition, Addison Wesley
Online lecture notes
Prerequisites
Coursework on (or experience with) Algorithms, Operating Systems, computer architecture is recommended but not required
CSE 2421, CSE2431, or ((ECE 2560 or ECE 265) and CSE 2451)
C/C++ Programming skills/experiences
The textbook is XXX
It is a classic book and it is the most widely used textbook.
One thing is that this book is updated every one or two years. So the current version is 6th version.
The book is not cheap, about one hundred bucks.
So it is OK to use the fifth version (if you have a cheap second-hand book). But please notice there are some updates and changes. You can go to the author’s website to get more information.
“lectures”
In some lectures, we might be slightly different from the textbook. Please refer to our lectures.
Let me quickly get through basic course information. You may know it already.
This is a course mainly open to senior and graduate students.
It is because the networking course requires your basic understanding or experience on Algo, OS, arch and programming language.
CSE2431: OS; CSE2451: C programming; CSE2421: Low-Level Programming and Computer Organization

7. Course Information (cont’d)
Introduction (first) course to computer networking
Chapters other chapters
Protocols: Application/Transport/Networking/Link Layers
What are you expected to learn?
Understand the basic concepts of computer networks: design and practice
Learn the basics of TCP/IP protocol suite in the current Internet
Develop network programming skills
[Course information, coverage]
[Goals and expectation) you know what you can learn from this course?
First, XXX: This is an introduction course to computer networking. Through it, I hope and believe that you will learn basic concepts, principles and core design ideas and techniques.
Second, XXX: The current Internet is built on TCP/IP protocol suite. I hope that you will learn how TCP/IP works and also know why TCP/IP is designed in this way.
Last but not least, You can learn how to do network programming. You will be able to write codes to implement the existing networking technologies (network stacks), but also develop your own and improve the current network design.
