- online resources indicated on iCampus website.

None

- Introduction, media access control, layered models,

- Internet Protocol, IP routing, introduction to IPv6,

- DNS, e-mail, common protocols,

- Multimedia networking (streaming, VoIP, DVB),

- Network security and advanced topics.

- 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 lecture, 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 an 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.

- Lab report (20% of the final points),

- Oral exam (80% of the final points), all documents allowed.

- Traditional lectures,

- Labs in computer room allowing the student to use the theoretical concepts seen during the lecture on a simulated network (using Netkit simulation software).
