Computer- and Communication Networks

Course Number 705088 | Wintersemester 2019/20

Content

This course offers an introduction into the fundamentals of computer networks and communiction technology. It discusses the network layers typically found in today’s Internet-based communication. A focal point of this course are questions related to network security. Thus, protocols found in today’s networks are analyzed with respect to their function, their historical development, and their weaknesses.

  • Fundamentals
    • History of the Internet, most common types of networks, P2P technologies
    • How to attack (and defend) modern Networks? Where are their weaknesses?
    • Vulnerabilities, Tools, Protection mechanisms
  • Layers in the OSI Model
    • Data Link: Ethernet, Switches
    • Network: Routing, IPv4/IPv6
    • Transport: TCP/UDP
    • Application: HTTP, HTTP/2, TLS, WebSockets, …

Objective

The course aims to make the basics of computer networks accessible. Basic protocols and technologies are described, such as local networks or the Internet (TCP/IP). However, considering the dynamically envolving field, topical developments represent a focal point of the course. Therefore, the course attaches great importance to making this topical state accessible. Examples are HTTP/2 and Web technologies, such as WebSockets and Content Security Policies.
