Specific course objectives

This course examines some advanced topics in computer networks. A focus will be placed on network address translation, IPv6, congestion control, multimedia over IP, mobile IP (only MIPv6) and multicast communications. After this course students should have a good knowledge on how the Internet works and they will be able to understand technical papers in this area.

Course programme

Introduction
Circuit switching and packet switching. Routing and switching in the packet switched networks. Layered architectures & communication protocols. Network performance: analytical models and simulation.

Advanced IP networks
Network Address Translation; TCP/IPv6; MultiProtocol Label Switching.

Multiservice IP networks
Network traffic (taxonomy). QoS in IP networks: definitions, IntServ & DiffServ models. VoIP applications.

The switching node
Theoretical background of hierarchical routing. Address lookup algorithms and their computational complexity.

Congestion control in packet switched networks
Network congestion. A taxonomy of flow control schemes. Definitions of “efficiency” and “fairness”. Congestion avoidance & congestion recovery. Binary feedback scheme. Queue management & buffer management.

Scheduling disciplines
Work-conserving and non-work-conserving disciplines. FCFS, GPS, WRR, WFQ.

Multicasting
Multicasting in packet switched networks. Graph theory & multicast routing. Multicast routing protocols in IP networks (DVMRP, PIM-DM, PIM-SM).
