Opportunities and challenges in the context of next generation optical access networks
Fixed access networks are expected to be subject to significant changes in
the future years. On the one hand, in telecommunication networks the evolution
from service-specific networks ("stovepipes" per service) towards next
generation networks (NGN) with a universal layered architecture can be observed
in its beginnings. On the other hand, due to the ever increasing access bit rate
demands optical fibres are pushed further to the customers with a pure optical
fibre to the home (FTTH) network as the target network architecture. Both trends
together "NGN in combination with FTTH" are expected to result in a change of
the networking paradigm and give the opportunity for a true next generation
access network allowing a network re-configuration with the overall target of a
cost-optimized service delivery. Future access networks will be very different
from the conventional telephone access networks: In particular the physical
characteristics of optical fibres (low attenuation, high bandwidth) allow for
large areas to be served from a single access network node enabling network node
consolidation and savings of operational expenditures.
This workshop will provide insight in the main trends in optical access
networks. Architecture and technology aspects are covered as well as business
impacts and opportunities of next generation optical access (NGOA) networks.
Technical and economical drivers will be discussed. From technology point of
view different options will be discussed like active and passive optical network
approaches. Fixed-mobile convergence related aspects will be highlighted, too.
Future evolution scenarios will be elaborated and possible research directions
and future access network paradigms will be outlined, motivated and discussed by
expert speakers from industry and academia. From a business perspective the
impact of business models on network design and operation will be highlighted. A
closing panel discussion will reflect on similar or deviating approaches and
identify the key research challenges and practical deployment issues.
