Objectives
The goal of this course is to provide students with competences in the area of content distribution in computer networks, including multimedia, and on how an IP network can support quality of service for different content types.
Learning outcomes and competences
At the end of the course, students will be able to
- design and configure an email infrastructure in an enterprise network,
- dimension and analyse the performance of a global web content delivery infrastructure,
- evaluate and improve the performance of multimedia content delivery systems,
- analyse, design and configure quality of service mechanisms in IP networks
Working method
Presencial
Pre-requirements (prior knowledge) and co-requirements (common knowledge)
Knowledge in data communication networks, including principles and concepts of network architectures, main networking technologies and solutions in use, TCP/IP protocol stack, common networking tools, including wireshark, programming and Linux OS.

Eligibility for exams
Completion of all proposed laboratory assignments and article review/ seminar.
Calculation formula of final grade
0.4 L + 0.4 E +0.2 S
L - mean grade obtained in the laboratory assignments
E - exam grade
S- seminar grade
Examinations or Special Assignments
The grade of the distributed component is given based on the laboratory assignments and seminar (review and presentation of one article). As such, the fulfillment of all laboratory assignments is mandatory for all students enrolled in the course, regardless of their type of registration.
Internship work/project
N/A
Special assessment (TE, DA, ...)
The fulfillment of all laboratory assignments and the article review is mandatory for all students enrolled in the course, regardless of their type of registration.
Classification improvement
The improvement of the classification obtained in the distributed component is not possible
Observations
To pass the course the student must obtain a minimum of 50% in each evaluation component.
Students should have basic knowledge of programming and computer networks.
