Course Objectives:

This graduate-level course covers the book “Computer Networks, An Open Source Approach” published by McGraw Hills. The book was motivated by an observation that none of the previous textbooks on computer networks really demonstrate where and how network protocols and algorithms are implemented in real systems. This course covers why and how various protocols and algorithms are designed (domain knowledge) and implemented (hands-on skills) into Linux kernel, drivers, and various daemons. In short, physical and data link layers are embedded into network adaptors and their drivers, while IP and TCP/UDP layers are built into kernel; and various application servers stand as daemons.

The lectures start from Chapter 1, next a two-hour supplement on the emerging network cloudification by Software Defined Networking (SDN) and Network Function Virtualization (NFV), plus 4 appendices, and then resume Chapters 2-8. A comprehensive set of fifty-six live open source implementations spanning across hardware (8B/10B, OFDM, CRC32, CSMA/CD, and crypto), driver (Ethernet and PPP), kernel (longest prefix matching, checksum, NAT, TCP traffic control, socket, shaper, scheduler, firewall, and VPN), and daemon (RIP/OSPF/BGP, DNS, FTP, SMTP/POP3/IMAP4, HTTP, SNMP, SIP, streaming, and P2P) are interleaved with the text

The loading for students includes (1) 6 quizzes during class hours, (2) 7 homework sets for the 8 chapters (hand-writing and hands-on), and (3) midterm and final exams. Course slides for each chapter are downloadable from the course homepage. Class lectures are in English.
