  Please note several peculiarities of this lecture (compared to traditional German lectures):

  • Participating in this course requires the ability and some experience in C coding.
  • You need to have a computer where you can run the VMWare Player, which runs on Linux and Windows.
  • The lecture will heavily base on discussions and interaction with the students.
  • For some dates, students have to read papers, chapters or texts in advance, and may be asked to present it to the audience. (This follows the concept how lectures are held at top-level U.S. universities. ;-)
  • Details of the pecularities of this course will be discussed in the introductionary meeting on April 10th. Please attend!

  Contents

  This course will focus on the Engineering of Communication Protocols and their embedding in operating systems.

  Topics will be:

  • Network architectures, Layering models
  • Interfaces, services, and instances in layering models (horizontal, vertical communication)
  • Life cycle of protocol and communication systems development
  • Protocol design, maybe specification languages (only briefly)
  • Implementation of communication protocols on the application layer
    • Overview on Berkeley Sockets, socket programming, etc.
    • Threads and synchronization of concurrent tasks
    • Pthreads, processes, etc.
    • Synchronization and deadlock avoidance
  • Architecture of Operating Systems (briefly)
  • Architecture of communication subsystems and their embedding into the OS (example: Linux, FreeBSD, maybe also Windows and TinyOS)
    • Interrupts, drivers, etc.
    • Concurrency (Tasklets, kernel threads, locking, synchronization etc.)
    • Memory management
    • etc.
  • Communication protocols in the Linux OS (maybe also briefly Windows and TinyOS)
  • Design and concepts of protocol desgin (for efficiency, resilience, etc.)
  • Interfaces and typical data structures
  • Interaction, coordination, etc. between the protocols and the OS
  • Discussion of protocol examples on layers 1 - 4
