Content

Telematics = telecommunications + informatics (often also called computer networks) covers a wide spectrum of topics - from communication engineering to the WWW and advanced applications.

The lecture addresses topics such as:

Basic background: protocls, services, models, communication standards;
Principles of communication engineering: signals, coding, modulation, media;
Data link layer: media access etc.;
Local networks: IEEE-Standards, Ethernet, bridges;
Network layer: routing and forwarding, Internet protocols (IPv4, IPv6);
Transport layer: quality of service, flow control, congestion control, TCP;
Internet: TCP/IP protocol suite;
Applications: WWW, security, network management;
New network concepts.

At the End of this course, you should...

know how networks in general are organized
know what the Internet could be or is
understand how wired/wireless (see Mobile Communications) networks work
understand why/how protocols and layers are used
understand how e-mails, videos get to where you are
understand how operators operate real, big networks
understand the cooperation of web browsers with web servers
be aware of security issues when you use the network
be familiar with acronyms like: ALOHA, ARP, ATM, BGP, CDMA, CDN, CIDR, CSMA, DCCP, DHCP, ETSI, FDM, FDMA, FTP, HDLC, HTTP, ICMP, ICN, IEEE, IETF, IP, IMAP, ISP, ITU, ISO/OSI, LAN, LTE, MAC, MAN, MPLS, MTU, NAT, NTP, PCM, POTS, PPP, PSTN, P2P, QUIC, RARP, SCTP, SMTP, SNMP, TCP, TDM, TDMA, UDP, UMTS, VPN, WAN, ...

Prerequisites

As this is a Master Course you have to know the basics of computer networks already (e.g. from the OS&CN BSc course or any other basic networking course). That means you know what protocol stacks are, know the basic ideas behind TCP/IP, know layering principles, got a rough understanding of how the Internet works. This course will recap the basics but then proceed to the more advanced stuff.

Resources & Organization

The course comprises about 30 "lectures", 90 minutes each, following the inverted or flipped classroom principle. I.e. you will be able to access a video of the lecture before we discuss the content in class. To be able to discuss you have to watch the video BEFORE we meet! This is your main assignment - go through the video, prepare questions if something is not clear. During the meetings there will be a recap of the main ideas plus enough time to discuss each topic if necessary.

This course has three time-slots blocked: Monday 14-16 (HS), Tuesday 14-16 (046), Wednesday 12-14 (HS). Due to time constraints, the meetings in presence will not always happen the same day each week but pick 2 out of the 3 time-slots. Use the empty slot to prepare for the next meeting!

Be aware: This schedule might change - you will be informed!
