Learning outcomes

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

1 With respect to the AA referrng system defined for the Master in Electrical Engineering, the course contributes to the development mastery and assessment of the following skills :
  • AA1.1, AA1.2, AA1.3
  • AA2.1, AA2.3, AA2.4
  • AA5.1, AA5.2, AA5.3, AA5.5.
At the end of this course, the students will be able to
  • understand the architecture of communication networks,
  • identify the routing strategies which are best suited to a particular network topology,
  • understand resource management strategies allowing to guarantee a quality of service, particularly for multimedia communications,
  • design architectures allowing secure communications.
Transverse learning outcomes :
  • use a network simulation tool (Netkit),
  • configure network parameters of a Linux based system using low-level commands,
  • configure a router using a (Cisco) IOS-like syntax
