Description

The goal of this course is to study the concepts, design and analysis of the Internet networking systems. The first part covers the design of the Internet protocols including TCP/IP, ICMP, IGMP, and Multicasting protocols. The second part of the course will focus on performance analysis of flow and congestion control in end-to-end transport protocols. The third part of this course covers practical issues in designing a scalable networks including data collection using network utilities (such as ping, tcpdump, traceroute, Mgen/Drec and SNMP), throughput/response predicting, capacity planing, and overview of next generation Internet protocols such as IPv6, RTP/RTCP and RSVP. The course is analytical and simulation oriented (no programming!). Students in this course are expected to achieve a solid understanding of how to design and evaluate scalable networks and protocols using analytical and simulation techniques.
