| This course explores local area networking (LAN) and Internet architecture and protocols, with emphasis on Ethernet and TCP/IP, and OSI layers 3, 4 and 5. We study protocol details, the way they relate and interact with each other, and how they are applied in real systems. Applications such as Virtual Private Networks and Voice over IP, and technologies such as wireless networking and IPsec are also covered. LAN communication building blocks such as hubs, bridges, switches, routers, and their interconnection and addressing issues are studied in detail. Real network packet traces are used to highlight the differences between the textbook descriptions of these protocols and real world behavior. Prerequisite: SEIS645 |
