    7. Objectives, learning outcomes and obtained knowledge

    This is the third subject within the framework of the optical side-specialization. This subject will discuss the optical networks that are built of the optical components learned within the two earlier subjects of this side-specialization.

    The aim of the subject is to provide the basic knowledge on design, architecture, operation, maintenence, management, control, routing, protection, traffic engineering in multi-layer and multi-domain access - metro - backbone networks. The subject will also overview the basics of mathematical modeling of optical networks, that will enable understanding some of the above functionality.

    8. Synopsis
    Part I: Optical Backbone and metro aggregation networks (10 presentations + 4 exercises)

    Week 1: 
    ·         Optical network functionality
    ·         Optical network generations
    ·         Switched optical networks
    o   Towards optical packet switching: OFS/OBS/OPS

    Week 2:
    ·         Multi-Layer Optical-Beard Networks (1/2): ITU-T OTN, ITU-T ASON/ASTN

    Week 3:

    Week 4:
    ·         Internet over optical networks: requirements, packet transport, protocolls, Internet architecture, addressing, routing
    Week 5:
    ·         Design and dimensioning aspects of optical networks: logical / virtual topology, number of wavelengths per fiber,
              Wavelength assignment, number of ports, traffic grooming, multicast, energy requirements
    ·         Optical networks in practice - some examples

    Week 6:
    ·         Operation and management of optical networks: routing, TE, network management

    Week 7:
    ·         Protection and restoration of optical networks (1./2): availability, dedicated vs shared, techniques

    Week 8:
    ·         Protection and restoration of optical networks (2./2): multiple-failures, problems, models, methods, algorithms

    Week 9:
    ·         Optical virtual networks oVON/oVPN
    ·         SDN and NFV in optical networks

    Week 10:
    ·         Overview and modeling of physical impairments that impct routing and optical path length 
    ·         Constraining effects of physical impairments in routing
    ·         Elastic Traffic and Elastic Spectrum: OOFDM and N-WDM

    Part II:   Optical Access Networks (4 presentations + 2 excercises)
    Weeks 11 and 12:
    ·   optical access networks:
    o   point-to-ponit vs. point-to-multipoint systems
    o   PON systems, media access: TDM, WDM, hybrid TWDM, OFDM PON
    o   availability and protection of PONs

    Week 13:
    ·         Which is the best? For what purpose? Techno-economic trade-offs, performance, cost, etc.
    Week 14:
    ·         Design of Access networks, cost-analysis, cost-optimisation
    ·         fix-mobile convergence (FMC)
    9. Method of instruction

    oral presentation, laboratory work


    10. Assessment

    a.   Mid-term exam close to the half of the semester, roughly 50% of the material covered by the subject,
          Where the knowledge of the student must be at least 50%

    b.   Exam 

    11. Recaps

    Repeated mid-term exam is on the first week after the teaching is finished.

    After that there is no possibility for repeating the mid-term exam.

    12. Consultations

    Whenever needed starting from the first presentation up to the last exam.
    The consultations are not fixed in advance, but are available anytime upon agreement.
