OBJECTIVES
After an in-depth introduction to communication network concepts, circuit switching and packet switching, we study circuit switching dimensioning techniques, introducing traffic concepts. This is complemented with wireless communications networks dimensioning.
SYLLABUS
Lesson I: Introduction.
Teleservice and bearer services. Topologies. Basic and complementary telephone network: exchange types. Fixed and access networks. Routing. International organizations. Multiplex. Switching modes: circuit, message and packet switching. Open architecture. OSI protocol stack description. Application to packet switching.
Lesson II: Tele-traffic.
Traffic concepts and queuing theory. Offered, carried and lost traffic. Time and call congestion. Kendall notation. Little formula. Lost systems. Waiting systems. Application to system dimensioning.
Lesson III: Switching Networks.
Internal structure. Total accessibility networks and non-blocking networks. Cross points calculus. Stage decomposition. Clos networks. Cross points reduction: blocking probability calculus. Serial-parallel decomposition. Lee approximation. Application to digital systems. Spatial switching. Time switching. Switcher design and deployment.
Lesson IV: Routing Techniques.
Virtual circuits and datagrams. Routing algorithms. Optimum principle. Shortest path routing. Flooding. Distance vector based routing. Link state routing.
Lesson V: Cellular Telephone Networks.
Historical antecedents. Cellular paradigm evolution. Cellular deployment: Cellular geometry properties. Co-channel interference. Dimensioning. Cellular control architecture.
EVALUATION CRITERIA
Final exam in February and extraordinary exam in September.
