3Tele2 / Perf Eval (WS 19/20): 00 – Preamble
Main Research Topics (of your Lecturer :o)
q In general: architectures and protocols of communication systems
q Structure, design, performance evaluation, implementation, …
q For all types of communication: computer networks, voice communication,
data & multimedia content, technical communication (control devices)
q Special focus on security issues
q More specifically:
q Security requirements of communication services
■ Authenticity, integrity, confidentiality of
peer entities and exchanged data
q Security aspects of protocol mechanisms
■ What side “security relevant” side-effects are
introduced by specific mechanisms?
q How to protect communication infrastructures
■ Main issue: How to ensure availability of
systems and offered services?

Topics of “Telematics 2”
q Follow-up class of Telematics 1
q Telematics 1 treated:
q Basics of getting information through a network
q Protocol layers 1 to 7
q Network security basics
q Telematics 2/Performance Evaluation will cover the following topics:
q Introduction to performance evaluation
q Mathematical basics for performance evaluation
q Discrete event simulation
q Queueing theory
q Placing and sizing router buffers
q Evaluation of complex systems
5Tele2 / Perf Eval (WS 19/20): 00 – Preamble
If you would like to get a “hands-on” experience...
q There is an additional course – entitled „Simulative Evaluation of
Protocol Functions” (project seminar, 4 SWS) – which is designed to
give you a “hands-on” experience with network protocol functions and
simulation studies:
q Introduces a simulation environment and lets you add protocol
functionality
q Studied protocol functions: forwarding, routing, (interface queues),
connection setup, error-, flow- and congestion control
q Requires good programming skills
q Knowledge of C++ is an asset (but not a pre-requisite)
q Allows you to obtain in-depth knowledge of topics covered in Telematics I
and the techniques and art of simulation studies – because afterwards
“you did it!” :o)
q Inscription and welcome lecture: October 18th, 10am, Z1020

Formalities – Resources
q Slides are/will be available on the web site
q There will be no script;
q Secondary literature is sometimes beneficial (and will be cited)
q To give due credit where credit is due:
q The first slides we will use in this lecture have been prepared by the
authors of [KR04] J. F. Kurose and K. W. Ross (besides maybe some
additions, that I may introduce during the term)
q Additional material (text, pictures, graphs, pictograms, etc.) will
potentially be added from lectures given by Profs. Schiller, Carle, Karl at
the Universities FU Berlin, Tübingen, Paderborn, as well as many other
researchers all over the world
q Anything with Markov chains is based on slides of Dr.-Ing. Werner Horn
q Many thanks in advance to everybody, who contributed material that
may be adopted during the course of this class

Formalities – Some Books Recommendations
q J. F. Kurose & K. W. Ross, Computer Networking: A Top-Down
Approach Featuring the Internet, 2012, 6th edition, Addison Wesley
q Motivates why communication systems are built in a certain fashion by
starting out from the applications that they should support
(background reading, chapters on multimedia & QoS)

[La06] Averill M. Law, Simulation, Modeling and
Analysis. 768 pp., McGraw-Hill Education, 2006.
q General book on
simulation, both excellent
overview and in-depth
treatment. Not oriented
towards a single problem
area.
q If you want to buy only one
book, get this one.
Expensive, though.
q Main source of information
regarding discrete event
simulation

Formalities – Some Books Recommendations
q Very good book on
performance analysis in
general
q Treats simulation as well as
mathematical tools
(queuing theory) and
experimental design
q Examples heavily focus on
computer systems and their
architecture.
q The treatment of simulation
is not as thorough as in
[La06], but also very good.
