55105 - Communication Networks Design (Graduate Course)

Learning outcomes

Be able to solve engineering problems related to dimensioning and performance evaluation of telecommunication networks.

Course contents

This course is made up of two modules.

The former is devoted to the teletraffic engineering for telecommunication networks and is in common for all the degree courses. The modules presents the basic concepts of teletraffic, statistics of arrival and service processes and the Little law. Introduces queuing systems and reelated mathematical models based on Markov chain. Then presents examples of applications to circuit and packet switched networks. For circuit switching are described the Erlang formulas and their applications to trunk group, call center and switching fabric engineering. For packet switching the focus is on single server queue, and in particular it is studied the M/G/1 case, with examples of application.

The latter part of the course is different for the various degree courses. The module for Computer Engineering and System Engineering and Information Technologies extends the concepts presented in the former module with particular reference to priority queuing, network of queues and multiservice networks. The module for Telecommunications and Electronic Engineering is devoted to the design of high speed network interfaces, with particular refrence to the Gigabit Ethernet case study.
