1. Computer Networks CEN 5501C Spring, 2008 Ye Xia (Pronounced as “Yeh Siah”)

2. How is the course conducted? Please follow the lecture and reading schedule on course web page Assignments are all posted on course web page (under Lectures) Critical dates are posted on the web page

3. Course Coverage Overview of communication networks –Focus on the Internet Will teach networking knowledge –Pick up concepts, jargons and technologies But special attention will be paid to engineering the network –Principles and design of the network –Protocols –Algorithms Always consider: what are the issues and how they are solved?

4. Coverage Basic: network layers –Application –Transport –Networking –Data Link Integrated or advanced topics –Quality of service framework and mechanisms –Wireless networks –Advanced topics: peer-to-peer networks, network resource allocation

5. Principles and design Most communication networks are giant infrastructure. A lot is at stake. Need –Careful and good design, and/or –Can be evolved Objective: what is it used for –Limited or unlimited? What is its architecture? –Different components and what they do –How they are realized: implementation and technologies What are the design principles: for coping with complexity –To ease designer, implementer, or user’s lives

6. Protocols and Algorithms Algorithms: formal procedure to accomplishing some task Protocols: governs the information exchange and collective behavior of distributed entities –For certain tasks Important components in networks

7. Network Programming Learn some network programming –through project But, not a focus.

8. Why This Course? Obvious: –Learn about the internals of the Internet –Learn network programming –Related to other core areas of CS: (distributed) operating systems –For some: continue with advanced network courses Less obvious: Learn about distributed, complex systems –Typical issues, solutions, design and architecture –Coping with complexity and scale

9. Textbook Computer Networking: A Top-Down Approach Featuring the Internet, 4th Edition by James F. Kurose & Keith W. Ross
