Course Description

CIS553 is a graduate course in Computer Networking that gives a top-to-bottom treatment of computer networking.

The course begins with an overview of communications systems, then progresses through a series of logical "layers", each of which carries out roles in the networked system. We start with (1) "physical layers" such as radio, optical fiber and copper wiring, and rise through a series of functional abstractions (naming, addressing, routing, ...) that comprise a "stack" of protocol layers used by applications. These include: (2) the link layer which uses the physical layer to communicate, and manages device identity and access to the medium; (3) the network layer which connects sets of participants using link layers; (4) the transport layer which provides services required by applications such as reliable byte-streams.

The course will involve six programming projects and two written exams.

Undergrads and other students who need a permit should add themselves to the waitlist. The waitlist will be processed in batches closer to the beginning of the semester and shortly after the start of the semester.

Optional Textbooks

Computer Networks: A Systems Approach (5th Edition). Larry L. Peterson and Bruce S. Davie.
Computer Networks (5th Edition). Andrew S. Tanenbaum and David J Wetherall.
Computer Networking: A Top-Down Approach (6th Edition). James F. Kurose and Keith W. Ross

Prerequisites

CIS 121 (Programming Languages and Techniques II), equivalent programming experience, or permission of instructor. Data structures and basic probability. Course projects will be in C++, Python, and P4 but prior experience in these languages is not strictly necessary.

Grading


Late Policy

You start with of 96 "slip" hours, subtracted in 1-hour increments. If your balance reaches zero, you will receive half credit for any assignment that you turn in, as long as you turn it in within one week of the due date.

Schedule

Schedule is in flux. Please check back regularly.

Optional readings refer to the Peterson/Davie book, unless otherwise specified. Equivalent material can be found in the other textbooks.
