Learning outcomes

At the end of this learning unit, the student is able to :

Given the learning outcomes of the "Bachelor in Engineering" program, this course contributes to the development, acquisition and evaluation of the following learning outcomes:
  • AA.1.1, AA.1.2
  • AA2.5-7
  • AA3.2
  • AA4.1-4
Given the learning outcomes of the "Bachelor in Computer science" program, this course contributes to the development, acquisition and evaluation of the following learning outcomes:
  • S1.I7
  • S2.2-4
  • S4.3
  • S5.2-5
  • S6.2-3
Students who have successfully completed this course will be able to
  • Explain the communication needs of the different classes of distributed applications handling data or multimedia streams
  • Explain the distribution of functions that satisfy these needs in the different layers of the reference model
  • Explain the realization of these functions in Internet protocols 
  • Choose solutions according to the needs of their application
  • Quantify the characteristic quantities involved in the networks
Students will have developed methodological and operational skills. In particular, they have developed their ability to
  • Argue to highlight the positives and negatives of a solution and make suggestions for improvement;
  • Write a summary report containing the elements that we wish to highlight.
Basic principles of network operation (reliable transfers, routing, naming/addressing, resource sharing, basic notions of security, etc.)
Analysis of the main protocols used on the Internet (HTTP, DNS, TLS, TCP, UDP, IP, OSPF, BGP, Ethernet, WiFi, ...)
Teaching methods
The course combines lectures, supervised exercise sessions, group work and personal work.
Evaluation methods
The assessment consists of four parts:
  •     a group project worth 3 points out of 20
  •     an individual review of two group works, worth 1 point out of 20 
  •     participation in courses, inginious and configuration exercises, worth 3 points out of 20 
  •     the final exam, worth 13 points out of 20 points
Students who actively contribute to educational materials can earn bonus points.
Projects and reviews associated with the project and  inginious and configuration exercises can only be presented in the first session.
Other information
  •     high level programming language
  •     Unix environment
