ECE9140 Computer Networks

• Computer Networks and the Internet
• Application Layer (HTTP, SMTP, FTP, DNS…)
• Transport Layer (TCP, UDP)
• The Network Layer (IP, Switch, Router)
• The Link Layer: Links, Access Networks and LANs
• Wireless and Mobile Networks (802.11, 3G, 4G)
• Multimedia Networking (Streaming, VoIP, RTP…)
• Security in Computer Networks (SSL, VPN…)
• Network Management (SNMP)

This course will introduce students to fundamental concepts of computer networks and widely used technologies and protocols such as HTTP, TCP/IP, Ethernet, WiFi etc. A top-down approach will be followed, organized around the layered architecture of a network, which starts from the application layer and moves down to the physical layer. Students will learn how networking applications work and emphasis will be given on Web oriented applications like e-mail and the HTTP protocol.

With the successful completion of the course students should:

• Have comprehended the OSI model, as well as the principle of encapsulation as we move vertically in the protocols of the OSI model.
• Have hands-on experience with TCP and UDP through socket programming exercises.
• Understand the way the Internet Protocol (IP) works and the various routing algorithms of the Network Layer.
• Be able to distinguish the various protocols used in the Link Layer, especially the Ethernet which is widely used in Local Area Networks (LANs).
• Be familiar with concepts like IEEE802.11 (WiFi), MAC, network security and management.
