Computer networks

This course aims to present the architecture of the computer networks from a protocol perspective.

S1 3 ECTS 24h OPT EN Site web R. Aparicio-Pardo

First, networking basics are introduced, paying a special attention to how network services are organize in layers and how these services are implemented by standardized protocols.

Then, the different layers in the protocol stack are explored following a top–‐down approach. Finally, at each layer main protocols, algorithms and mechanisms are detailed.

Lectures
