Network models and protocols

Quadrimestre 2 -

General course description

Study of various types of networks: TCP/IP, telephone, X25, RNIS, Frame Relay, wide-band RNIS, Ethernet, Token Ring, FDDI, ATM, semaphore networks, wireless networks, value-added networks and the associated protocols.

Learning basic skills

The Introduction to networks and telecommunications course (first year).

Course Aims

  • To gain a better understanding of the concepts of network architecture and the related terminology
  • To gain an insight into the role and objective of each layer and component of a network
  • To understand the developments of networks
  • To be able to analyse the need for coherence between the data flows of various software applications and the network
  • To be able to locate a layer when talking about a given protocol
  • To have an understanding of the specificities of each type of network.
