Theory of Digital Networks

Registration

A moodle-course is now available for registration. We will use moodle to post the exercise sheets and other material.

Examination

The exam will be oral.

For the exam in Theory of Digital Networks

For English speaking students:

the following chapters/sections from Gallager/Bertsekas are relevant:

Chapter 1 Introduction and Layered Structure

Chapter 2 Point-to-Point Protocols and Lines (without 2.10)

Chapter 3 Queueing Theory (without 3.6, 3.7, 3.8)

Chapter 4 Multiaccess Communications (without 4.6)

Chapter 5 Routing (only 5.1-5.3 thus without 5.4-5.8)

Chapter 6 Flow Control (only 6.1)

For Germans:

Die folgenden Kapitel/Abschnitte von Bossert/Breitbach sind prüfungsrelevant:

Kapitel 1 Grundbegriffe

Kapitel 2 Hierarchische Struktur

Kapitel 3 Verfahren zur Datenübertragung

Kapitel 4 Vielfachzugriffsprotokolle

Kapitel 5 Zuverlässige Datenübertragung

Kapitel 6 Routing und Flusskontrolle

Kapitel 7 Warteraumtheorie (nicht Abschnitt 7.8)

Nicht Teil II Systembeispiele

The lecture describes and analyzes the basic functions of protocols and explains the most important algorithms and methods, which are used in communication systems. The exercises complement the lecture by applying the theoretic knowledge to special problems.

The lecture usually includes an excursion to a working telecommunication network. The lecture is intended for Master students in electrical engineering, possibly also for students in computer science and mathematics.

Concepts and definitions of digital communication networks
Data transmission from point-to-point
Synchronization aspects
Multi-access protocols

Carrier-Sensing (with and without collision detection)
Techniques for reliable data transmission (ARQ- and hybrid-ARQ techniques)
Routing algorithms, flow in graphs, shortest path routing
Markov-chains
Queuing theory
Lossless and lossy queuing systems
possibly: Network Coding
Project orientated lab: ARQ, Markov chains, simulation of queuing systems
