*Session description*

The advancements in telecommunication networks during the last 30 years have
revolutionized our lives, our social behaviour, the way we communicate, the
way we
work, the way we learn, and it is even at the heart of numerous innovative
companies
around the world.

If there is one sector that has been impacted the most by this evolution,
that one is
the telecommunication industry. In order to accommodate the evolving
requirements
of their customers, network operators have developed a wide range of
technologies
e.g. mobile radio, satellites, optical fiber, UMTS (Universal Mobile
Telecommunications System) or 3G radio networks. Huge investments were
needed
to accommodate the increasing demand of bandwidth and to provide service to
the
exponentially growth of connected devices. The network operation had to
evolve
accordingly, in most cases just with the adaptation of the existing
Operation Support
Systems (OSS), but without being able to drastically reduce the technical
personnel
needed for the maintenance of networks and services.

This situation is going to be exacerbated in the near future, with the
explosion of the
Internet of Things, where every device will be able to connect to the
network and
exchange data with other devices in the ecosystem. To this end, there is a
high
demand for optimised network management solutions and simultaneous
provision of
higher levels of broadband access to more demanding customers. The latter
should
be also materialised to reduced or at least constrained Total Cost of
Ownership
(TCO), and especially the Operational Expenditures (OPEX). New dominating
trends
including Software defined Networks (SdN) and Network Function
Virtualization
(NFV) promise minimization of the [cost * complexity]/ [performance *
functionality]
ratio, as well as flexibility, diversity and security. Such emerging
technologies offer
enhanced features, however a key question remains: can they really solve the
network operation and management issues faced today by network operators?
For
example, SDN provides the ground for easing the management of the network
resources. What about the management of the network virtualisation process
itself?
Moreover, will the new technologies smoothly fit into the current OSS
ecosystem, or
will their integration require strong adaptations that just add complexity
to it, as it has
already happened in the past? And will the research solutions developed
during the
last years be able to accommodate these new trends? The operational
challenges
implied by them should not be underestimated, and need to be carefully
analyzed by
the network operators for the implementation roadmap. On one hand, the
management of these emerging technologies like SDN and NFV implies an
evolution
or even a revolution (a clean slate design) of the current OSS map. On the
other
hand, the resulting management ecosystem must be able to govern the
complexity
and dynamicity of the future networks and the scalability issues derived
from the
explosion in the numbers of connected devices. This session target is to
shed light to
these important challenges.

The Network Operators perspective on Future Networks challenges session
aims to
provide a forum for network operators, industry and researchers to present
and
discuss network operators views for advances towards the Future Networks.
The
focus lies on emerging management, operation and governance schemes for
future
networks and Internet technologies. The sessions participants will be able
to learn
how to think differently on network management, from three complementary
points of
view. On the one side they will be given the chance to look behind the
curtains of
network operators focusing on the challenges and possible solutions
foreseen for
network governance in the mid- and long- term, taking into account not only
the
current situation but also the requirements introduced by the emerging
technologies.
In addition, they will be able to approach the vendors point of view on
the practical
implications of these trends, their applicability and their proposals for
gradual
deployment and migration. Finally, the fresh vision of the academia on the
open
research topics will highlight how the cooperation between academics and
industry
can help to build solutions for current and future management problems.
