Course contents

Introduction to performance evaluation in Communication and Computer Networks

TELETRAFFIC THEORY

Introduction to teletraffic theory and queuing systems.
Markov chains and birth-death processes.
Markovian queuing systems and the Erlang formulas.
Application to analysis, dimensioning and planning of circuit and packet switched networks.

END-TO-END CONTROL AND TRANSPORT LAYER PROTOCOLS

Overview of the TCP protocol.
TCP flow and congestion control: the AIMD concept.
Mathematical models to estimate the throughput of a TCP connection.

VIRTUALIZATION AND SOFTWARE DEFINED NETWORKS

Principles of network "softwarization."
Separation of the control plane and the data plane.
Issues related to virtualization of network functions.

Readings/Bibliography

Teaching methods

Lectures and practical exercises in the classroom.

Case studies will be illustrated related to real-life examples of application of the course concepts.

Assessment methods

The final exam is based on a written test on queuing systems and TCP protocol performance evaluation. Each student will be asked to solve three exercises of the same type as those presented in class and available as handouts. The duration of the written test is between two and two and a half hours, depending on the difficulty of the exercises proposed. Students will not be allowed to consult textbooks, notes or other material during the test.

Teaching tools

In case of possible practical exercises, open-source software tools will be used for traffic analysis and performance evaluation.
