A study of the theory of computer networking focusing on the TCP/IP Internet protocols and covering the five layers in the model: physical, data link, network, transport, and application. Communication on wired, wireless, and cellular networks will be covered. Introduction of secure communication and its incorporation into different layers of the model. As part of the laboratory component, students will learn systems programming as it relates to interprocess communication over sockets, I/O handling, process and thread control, and the development of client/server programs. Prerequisite: CMPS 2020 with a grade of C- or better Programming in a high-level language (preferably C/C++)
Data structures and algorithms
Familiarity with programming in a command-line environment (e.g. gcc, g++, gdb)
It is strongly recommended that students be calculus-ready before taking this course 4 semester units. 3 units lecture (150 minutes), 1 unit lab (150 minutes).

The course maps to the following performance indicators for Computer Science (CAC/ABET):

(CAC PIa1): Apply and perform the correct mathematical analysis.

Apply statistical methods including the binomial and Poisson distributions to analyze common networking scenarios such as Ethernet contention, error rates, queueing theory, and channel efficiency.

(CAC PIa2): Prepare and solve the appropriate physical model of the problem.

Apply Shannon's law and Nyquist's theorem to appropriate models of the physical layer of the networking stack.

(CAC PIe2): Recognize and describe current issues in security.

Describe at least one protocol that adds security to the TCP/IP protocol stack. Analyze scenarios involving network security such as the appropriate use of security techniques for a given scenario and the limitations of common encryption protocols.

(CAC PIi1): Program in a suitable computer language.

Use the socket API for the TCP/IP protocol stack to code a simple client-server application in the C programming language.

(CAC PIi3): Utilize problem solving skills and techniques to complete the task.

Analyze common networking scenarios and apply the appropriate techniques to derive a solution.
