Overview
This course provides a broad introduction to computer networking. It addresses all four major architectural layers of modern computer networks (application layer, transport layer, network layer and link layer), as well as selected topics from multimedia networking, wireless networking and network security. Application layer topics include basic network programming and application layer protocols, including the protocols that underlie the world-wide web, electronic mail, the domain name system and peer-to-peer applications. Transport layer topics include the User Datagram Protocol (UDP), principles of reliable data transfer and the Transmission Control Protocol (TCP). Network layer topics include several key protocols from the Internet protocol suite (IPv4, ICMP, DHCP, NAT and IPv6), plus router data plane functions, general network routing algorithms and the specific internet routing procols, RIP, OSPF and BGP. Link layer topics include multi-access protocols, Collision-Sense Multiple Access with Collision Detection (CSMA/CD), Ethernet, link layer switching, and Virtual Local Area Networks (VLAN). Wireless topics include WiFi, cellular wireless networks and mobile IP. Prerequisite: CSE 241. Credit: 3 units.
