Broadband European Leadership”
• What is the NOBEL main goal ?
– To carry out analysis, feasibility studies and
experimental activities on innovative solutions and
technologies for intelligent IP/optical networks
• Why this goal ?
– There is the need to solve core and metro networking
bottlenecks such as: architectures for interworking
and interoperability, solutions for provisioning

NOBEL is aiming at bringing innovation in core
and metro networks for BB4A services
Main Areas
State-of-Art and Open Issues
Innovation by NOBEL
Architectures,
solutions for core
metro networks
Current TDM transport networks (e.g. SDH based)
were basically designed for voice and permanent
leased-lines services. They are not optimized for
IP/MPLS traffic.
NOBEL network solutions, also involving
advanced GMPLS / ASON and burst/packet
techniques, will be optimized to reach full
integration of data, voice and video transport
strongly increasing the operational efficiency and
the quality of end-to-end broadband services.
Resilience
The absence of a cohesive survivability approach
in present multi-layer networks can cause
contentions among layers and inefficiencies.
NOBEL multi-layer survivability strategies will
optimize the allocation of network spare resources
(thus reducing CAPEX), and will avoid contentions
among layers.
Network resources
optimization
Present networks don’t allow multi-layer resource
optimization, thus resulting in waste of CAPEX
and reduced efficiency.
NOBEL promotes Multi-layer TE, Capacity
Management strategies and data agnostic
protocols to optimize resource and avoid
congestions.
Network Management
and Control
Present networks are managed through long and
inefficient provisioning procedures, with a negative
impact on OPEX. Dynamic routing and discovery
(control plane) in multi-layer, multi-domain
networks are still unsolved issues.
NOBEL Control Plane will allow automatic
provisioning of connections, through automatic
topology discovery and transport routing. Also,
inter-working between Control and Management
Planes will be enabled.
Transmission aspects
Until now, the full exploitation of (true) optical
transparency has been prevented by the difficulty
of dynamic setting of optical paths.
NOBEL control plane will enable the dynamic
configuration and automatic set-up of transparent
optical paths through the transport network.
Services
Bandwidth on demand connectivity services are
desirable but not easily compatible with existing
network technology.
NOBEL control plane will enable the offering of a
new class of services: e.g. Bandwidth on Demand
and Dynamic Optical VPN network services,4etc
