Remark:

We will offer the course Internet Transport in a format considering the possibility for as well students as lecturer and tutors to give and / or consume parts of the course online using web-conference tools:

The course Internet Transport is a revised and updated version of the courses Media Transport resp. Future Media Internet. Hence in case you already successfully passed an earlier version you cannot gain credit points anew!

  • Course material, quizzes and assignments will be done in Moodle.
  • Lectures will be offered in Teams, in a hybrid fashion (lecture hall plus Teams).
  • The content will be based on our IT-book that is available in various formats (ipynb, pdf, html).

Course Details

Classroom

The lecture will be offered in a hybrid format (classroom plus remote participation via MS Teams). Under special circumstances it might be advantageous or even required to omit the classroom and switch to fully remote. This will be announced on time.

For participating remotely please join the MS-Teams Team by sending a join request under the following link: IT SS 2024 Team

Introduction

More than 20 years ago researchers observed distruptive changes in network and service architectures: Everything over IP, IP over Everything, inspired by the push of telephone companies towards Voice over IP, created the vision of a unified network and service architecture. The core observation has been that the internet—represented by its core-protocols, i.e. IP on the so-called network layer and TCP on the so-called transport layer—can be run over nearly all physical media (IP over Everything (IPoE)) and in addition can be used to carry any form of data imaginable: texts, images, graphics but also media like voice, radio or television (Everything over IP (EoIP)).

The course Internet Transport will introduce the requirements for the transport of media and other time-critical data over the Internet, introduce proper channel models, calculate the channel capacity of those channels and derive a framework for optimised media transport. We will look into both domains, the time and the reliability domain, showing that they partially contradict each other and that the transport—supported and partially enabled by the lower and the higher layers—needs to be rethought to fullfill the requirements of EoIP/IPoE. Besides giving an overview over recent specifications and standards (TSN, DASH) the course will introduce latest research results on predictably reliable transport protocols.

Prerequisites

Digital Transmission & Signal Processing as well as Audio/Visual Communications and Networks are recommended for this course. Students with solid background in Computer Networks and Error Correction, however, are also encouraged to participate.

Course Structure

Basic Rules

  • Please note that small changes and corrections will be applied to the lecture notes throughout the semester. If you find mistakes or have suggestions how to enhance the lecture notes we appreciate your input!

Exam Dates

  • The exams will be held as ORAL exams
  • Main Exam - Calendar Week 32, Exact Dates & Time: tbd
  • Re-Exam - Calendar Week 38, Exact Dates & Time: tbd

We will schedule all exam slots via Moodle. The exact time of each slot and how you can choose a certain slot will be announced at a later date.

Task Sheets

  • Task sheets are published on Thursdays and are available online.
  • You submit your solution and work on the tasks up to and including the following tutorial.
  • During the tutorial you can discuss and evolve your solutions and get up to three additional points.

Correction

  • The quizzes and task sheets for this course will be divided into two parts (6 each in blocks A&B). It is necessary to pass both the blocks individually to be eligible for the exam.
  • Weekly Quizzes and Task Sheets:
    • Each weekly quiz are worth 5 points total, which adds up to 30 points total for each Blocks A&B. These points can be earned individually by everyone.
    • Each task sheet contains minimum 3 tasks, which adds up to 18 points total for each Blocks A&B. These points can be earned if you individually can demonstrate your understanding on the task during the tutorial and by your submitted solutions.
    • Final points are calculated by adding up over all quizzes and task sheets within a block.
    • You need minimum 40% in total to pass a block and must pass both block A and B to be eligible for the exam.
