CS 6543 Computer Networks

Summer 2017


Course Description

6543 Networks
(3-0) 3 hours credit. Prerequisite: CS 5523. This course introduces the underlying concepts and principles of modern computer networks, with emphasis on protocols, architectures and implementation issues in the Internet.


Using the Internet as a vehicle, this course first introduces the underlying concepts and principles of modern computer networks, with emphasis on protocols, architectures, and implementation issues. Students learn how/why these protocols and architectures work while understanding the principles and tradeoffs involved in building such protocols and architectures. Secondly, the course covers advance topics including wireless networks, quality-of-service (QoS), cloud networking.

Students will also gain experience in performing research through reading, implementing and evaluating research papers.

This year, Term projects will be about Software Defined Networks (SDN) and Cloud Networks ....

Computer Accounts

You will have an account on the CS network as long as you are enrolled in a CS course at UTSA. This account gives you access to Windows and Linux in various CS laboratories. You may also access your account from off-campus via the Internet using secure shell. A free version of secure shell is available at http://www.cs.utsa.edu/~javalab/lab/SSHSecureShellClient-3.2.0.exe, if you wish to install it on your home machine.

After installing and running SSH: Click Quick Connect, enter hostname as the hostname, enter your cs account id (first initial followed by up to 7 letters of your last name) as username, then click connect. First time it may ask if you want to save keys etc., say yes then enter your password...

Your CS account name will usually be your first initial followed by up to 7 letters of your last name. However, account names sometimes vary because of name conflicts. New account names are posted in the lab. Your initial password is your 8-digit student ID without the leading @ sign.

Course expectations for professional conduct

Students will treat their classroom obligations as they would any serious professional engagement. These obligations include:
