ECS 152A COMPUTER NETWORKS (4 units)
Lecture: 3 hours
Discussion: 1 hour
Overview of computer networks, TCP/IP protocol suite, computer-networking applications and protocols, transport-layer protocols, network architectures, Internet Protocol (IP), routing, link-layer protocols, local area and wireless networks, medium access control, physical aspects of data transmission, and network-performance analysis.
Prerequisite: (ECS 060 or ECS 032B or ECS 036C); (ECS 132 or EEC 161 or MAT 135A or STA 131A or STA 120 or STA 032)
Credit restrictions/cross listings: Cross listed as Electrical and Computer Engineering 173A. Only 2 units of credit for students who have taken course 157.
Cross-listing justification: This course is integral to undergraduate programs in both departments. It is a required course for the Computer Science and Engineering (CSE) major in the Department of Computer Science and for the Computer Engineering (CE) major in the Department of Electrical and Computer Engineering. The department teaching the course will be responsible for staffing and for all the normal resources required for the course.

The course contains a series of design projects with 2-3 students per team. The projects are designed to reinforce certain concepts and to familiarize the students with network measurement tools and simulators and their use in protocol analysis. Example projects include: (1) designing a simulation model to compare performance of different medium access control protocols; (2) monitoring and analyzing network data collected using active/passive network measurement tools or a LAN analyzer; (3) design measurement experiments to analyze a particular performance metric or network anomaly; (4) introductory assignment to configure PC-based or commercial routers; (5) implement a simple client-server application.
Goals: Students will (1) learn the fundamental principles in communication networks; (2) understand the architecture and underlying protocols along with scalability, complexity and robustness issues of communication networks and systems; (3) be prepared to undertake an in-depth study of local area networks and wide area networks dealing with their access mechanisms, routing algorithms, and performance evaluation methodologies; (4) gain experience in the design and analysis of network protocols through experiments on a Ethernet LAN, network measurements, or through simulation models. Computer Usage:
Typically, students do their projects in the campus computer laboratories containing networked SUN, HP, and SGI workstations and Personal Computers (PCs) running LINUX. The simulation project can be done on other computers as well, such as PCs at home. The projects are typically done in the C, C++ or Java programming languages, although the simulation project can be done in any other high-level language as well.

Engineering Design Statement:
The course emphasizes techniques for designing and analyzing network protocols, from the application to the link layers. There will be both written and programming assignments in the class. In written assignments, students are presented with open-ended problems that require them to explore various approaches to network design, to choose between alternatives, and to justify solutions based on performance and cost/complexity considerations. The laboratory projects are design-oriented. Sample projects include: (1) design of elementary file transfer protocol, (2) design tools to collect and analyze network measurements, and (3) design of a simulation model to study the characteristics of various error control strategies or the effect of window size on delay and throughput, or to analyze medium access protocols.

Overlap: There is some overlap with course 157, but the audience is different. Course 157 is for non-majors and this course is designed for majors. There is some overlap with the introductory material of ECS 252A and EEC 273, Computer Networks, taught at the graduate level.
