Provide the students with knowledge on current telecommunication networks in order to understand their main characteristics.
The emphasis goes to the general architectures (both in terms of hardware and software) and to the way the networks are defined based on reference models.
It is also an objective that the students become familiar with the various physical layers (guided, not guided, etc.) and feel the need for a data link layer as well as the medium access control sublayer to access a shared medium. For each layer (or sub-layer) some real networks are studied. It is important that the students acquire enough critical knowledge about the main technical choices made for each of the example networks. The theoretical syllabus goes up till the Network layer (excluding it).
The laboratory part consists on learning how to use the socket interface both using TCP and UDP in order to provide the students of enough knowledge that will be important in future courses in the degree.
