EECS 489: Computer Networks

Instructor: Z. Morley Mao

Course Homepage: http://www.eecs.umich.edu/courses/eecs489/w10/

We study how networks operate and how network applications are written. We study the workings of the Ethernet and the Internet: how packets are routed, how packets are transmitted, and what to do when there is network congestion. We look at packet headers and routing and transmission protocols. We learn what sockets are and how to use them. We write code to implement various routing and transmission protocols. We write code to build client-server applications. There will be a lot of programming.
