Syllabus

Course Objectives

  1. Knowledge and Understanding: At the end of the course, the student will have acquired fundamental knowledge of current and future digital telecommunication systems. The student will understand the characteristics of the main transmission media used in telecommunication systems, commonly adopted multiplexing techniques, and the principal multimedia signal coding standards. The student will be able to characterize the traffic profile generated by a multimedia source and will understand the key parameters for defining IP-level Quality of Service. The student will also be familiar with the protocols, technologies, and architectures used for multimedia content transmission over IP networks, as well as scheduling and queue management techniques discussed in the literature and the related mathematical models used to evaluate their performance under both UDP and TCP traffic conditions. The student will understand Internet QoS support models (IntServ and DiffServ), IP over ATM, MPLS, and IP over SDH systems. Furthermore, the student will acquire the knowledge required to assemble a small router from commercial electronic components and install and configure an open-source operating system (e.g., OpenWRT, ZeroShell).
  2. Applying Knowledge and Understanding: Upon passing the examination, the student will be able to develop and support arguments regarding the most appropriate choice of transmission media, multiplexing technologies, and related mechanisms. The student will be able to select appropriate multimedia encoders and estimate their traffic profiles. The student will be capable of managing IP-level QoS by properly selecting suitable technologies, algorithms, and protocols. Additionally, the student will be able to design, build, and configure a small router using off-the-shelf components and open-source software.
  3. Making Judgements: Upon passing the examination, the student will be able to independently conduct the analysis and design of a multimedia telecommunication system or its components. The student will be capable of identifying operational criticalities and proposing modifications to improve QoS, support new services, or increase system capacity.
  4. Communication Skills: Upon passing the examination, the student will be able to clearly explain the theoretical and technical motivations underlying modern multimedia telecommunication systems.
  5. Learning Skills: Upon passing the examination, the student will be able to independently learn about possible technological evolutions beyond those presented during the course and apply the evaluation methodologies acquired to emerging technologies.



Course Prerequisites

There are no mandatory prerequisites for this course.

However, students are strongly encouraged to have basic knowledge of the following topics:


  • Fundamentals of electrical engineering;
  • Interaction between systems and signals, including Frequency Response, Ideal Channels, Perfect Channels, and Linear Time-Invariant (LTI) systems;
  • Basic concepts of stochastic processes, with particular emphasis on Markov processes;
  • Fundamental operating principles of telecommunication networks, with particular reference to TCP/IP networks.



Teaching Methods

Frontal lesson, laboratory experiments and team work


Assessment Methods

Exams consist in an oral examination and in the implementation and discussion of a project (preferably a team project). The oral examination will aim at assessing the knowledge of topics dealt in the course, while the project implementation and discussion will serve the purpose to assess the ability of the students to apply the knowledge they have acquired to practical use cases.

 

The following evaluation criteria will be adopted.


30 – 30 cum laude — Excellent

The student:

  • demonstrates complete and detailed knowledge of the subject: knows the relevant contents, uses correct terminology, identifies and explains the main concepts, and integrates personal insights into their synthesis;
  • shows excellent understanding of the subject: clearly distinguishes between main ideas and supporting ones, frames the key points effectively, strengthens arguments with references to supplementary material or individual in-depth study, and develops interdisciplinary connections;
  • demonstrates well-established ability to apply knowledge and analyze results;
  • presents the subject in a clear and structured way: the presentation is organized, logical, mature, and concise.

28 – 29 — Very good

The student:

  • demonstrates thorough knowledge of the subject: knows the relevant contents, uses correct terminology, and identifies and explains most of the main concepts;
  • shows solid understanding of the subject: frames most of the key points, although not always clearly distinguishing between main and less important topics; discusses the subject with references to supplementary material or individual in-depth study;
  • demonstrates excellent ability to apply knowledge and analyze results;
  • presents the subject clearly and in an articulated manner: the presentation is organized, logical, mature, and essential, although with some minor inaccuracies.

25 – 27 — Good

The student:

  • demonstrates broad knowledge of the subject: knows the relevant contents, even if not fully explained; uses terminology, though not always precisely; identifies key concepts but is not always able to explain them fully or accurately;
  • shows adequate understanding of the subject: distinguishes important key points but is not always able to frame them completely;
  • demonstrates good ability to apply knowledge;
  • presents the material clearly, though not always completely, with a schematic organization and sometimes fragmented or repetitive ideas.

22 – 24 — Fair

The student:

  • demonstrates acceptable knowledge of the subject: knows most of the contents but shows gaps and some confusion in certain important (though not essential) concepts;
  • shows an essential understanding of the subject: does not always manage to frame all the topics or sometimes does so with some inaccuracies;
  • demonstrates fair ability to apply the fundamental concepts of the subject;
  • presents the material correctly, though without a fully clear and coherent structure, sometimes including less relevant material in the discussion.

18 – 21 — Satisfactory / Pass

The student:

  • demonstrates limited knowledge of the subject: knows the most relevant contents but shows several gaps; identifies many key concepts but cannot illustrate them fully or accurately;
  • demonstrates basic understanding of the subject: has some difficulty distinguishing key points and does not always frame them adequately due to incompleteness or inaccuracy;
  • shows some uncertainty in applying the fundamental concepts of the subject;
  • presents the material in a rather unclear and confused way, using language that is poorly organized, with fragmented and repetitive ideas and imprecise terminology.

Fail

The student:

  • demonstrates poor and fragmented knowledge of the subject: does not know the essential contents, shows extensive gaps, and fails to identify key concepts;
  • shows serious misunderstandings, does not answer many questions or fails to solve several problems, and makes errors in applying the fundamental concepts of the subject;
  • does not reach an acceptable level of reasoning and articulation related to the subject.
