34775 - Telecommunications Networks (2nd cycle)

Course contents

TELETRAFFIC THEORY

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

INTERNET ROUTING

• Architecture and performance of switching systems.
• Fast routing and switching: MPLS and GMPLS.
• Load balancing and traffic engineering

END-TO-END CONTROL AND THE TRANSPORT PROTOCOLS

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

VIRTUALIZATION AND SOFTWARE DEFINED NETWORKS

• Separation of the control plane and the data plane
• The OpenFlow protocol
• The ETSI NFV-MANO
• a typical VIM: OpenStack

Readings/Bibliography

Teaching methods

Lectures

Case studies referring to real life examples of application of teletraffic theory

Simulations of the TCP protocol with the ns2 simulator

 

Assessment methods

Written exam aimed to solve study cases of the topics addressed during the course.

The exam is in 4 parts:

• at least two practical exercises of application of teletraffic and TCP protocol analysis
• 1 or 2 questions requesting to present and discuss in written form topics studied in the course.

Teaching tools

Lecture notes provided by the lecturer.

For teletraffic theory and TCP analysis the teacher will present to the students some relevant scientific papers as examples of in depth works on the topics.

Regarding SDN and network virtualization additional tutorials and information can be found on the Education page of the IEEE SDN
