The purpose of this course is to introduce fundamental principles and concepts of computer networks. We will use a top-down approach to study the Internet Protocol stack. We will first study popular network applications such as Web, email, FTP, and P2P, then study communications services required to support these applications, and finally study how these communication services are implemented. Throughout this course, we will use the Internet's architecture and protocols to reinforce fundamental computer networking principles.

Computer Networking - A Top Down Approach Featuring the Internet

Computer Networking - A Top Down Approach Featuring the Internet

Text book:

The required textbook for the course is Computer Networking - A Top Down Approach Featuring the Internet Second Editionby James Kurose and Keith Ross (Addison Wesley). It is available in the CMU Bookstore. Almost all the material that we will cover is in the textbook, although we may cover it in a different order.
There are two recommended texts which are useful references (especially if networking becomes your career). You can get the best price on them by ordering from an on-line bookstore.


  • TCP/IP Illustrated, Volume 1 : The Protocols by W. Richard Stevens.
  • Unix Network Programming : Networking APIs: Sockets and XTI (Volume 1) by W. Richard Stevens.

Course Description

6.035 is a course within the department's "Computer Systems and Architecture" concentration. This course analyzes issues associated with the implementation of high-level programming languages. Topics covered include: fundamental concepts, functions, and structures of compilers, basic program optimization techniques, the interaction of theory and practice, and using tools in building software. The course features a multi-person project on design and implementation of a compiler that is written in Java® and generates MIPS executable machine code. This course is worth 8 Engineering Design Points.
