Course Description and Overview

ECOM 4321 is an undergraduate course in computer networks. We will cover the technologies supporting the Internet, from Ethernet and WiFi through the routing protocols that govern the flow of traffic, and the web technologies that are generating most of it.

We will study how routing, transport, and internetworking protocols work using the Internet family of protocols as examples.

A major concern is understanding the protocols used on the Internet: how they work, their shortcomings, what the issues are, and what improvements are on the horizon.

The course also covers network security.

6

Course Objectives

Develop an advanced understanding of the network design principles and performance metrics

Become familiar with the mechanisms and protocols for reliable data communication via a computer network

Be able to evaluate the performance of various network technologies and protocols

Think as an engineer: What technologies should be employed to build a network with particular specifications?

7

Course Outcomes

At completion of the course students should be able to:

Understand the layered structure of protocols Understand the importance of standards and who setsthem Understand the basics of network protocols, including, datagram/virtual circuit switching, forwarding, access control, data link control, IP, routing, transport protocols. Resulting in an understanding of how the Internet works. Understand the tradeoffs involved in network design in a variety of environments - LAN and WAN, diverse link rates, and varied error and delay conditionsPerform simple analytic performance and design trade-off studiesUnderstand the basics of network security, including public/private key systems, digital signatures, key distribution systems, and certificate authorities Be fluent in the language of communication networks, i.e., understand the meaning of networking terms and abbreviations

Required Textbook and Material

There is one official text for the course:

“Computer Networks: A Systems Approach”, Larry Peterson, and Bruce Davie, 5th edition, The Morgan Kaufmann Series in Networking, ISBN-10: 0123850592 | ISBN-13: 978-0123850591 | Publication Date: March 25, 2011The textbook teaches you the key principles of computer networks with examples drawn from the real world of network and protocol design. Using the Internet as the primary example, the authors explain various protocols and networking technologies. Their systems-oriented approach encourages you to think about how individual network components fit into a larger, complex system of interactions. Whatever your perspective, whether it be that of an application developer, network administrator, or a designer of network equipment or protocols, you will come away with a "big picture" understanding of how modern networks and their applications are built.
