3 Telematics 2 / Performance Evaluation (WS 17/18): 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 Multimedia Communications in the Internet q Internet QoS Architectures: IntServ/DiffServ q Multi Protocol Label Switching q Introduction to Performance Evaluation q Mathematical Basics for Performance Evaluation q Discrete Event Simulation q Queueing Theory q Evaluation of Complex Systems

5 Telematics 2 / Performance Evaluation (WS 17/18): 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 will take place today, 4pm, 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)

• Analysis. 768 pp., McGraw-Hill Education, 2006.

q General book on

simulation, both excellent

• verview 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.
