The Control Plane
Network Control Protocols (NCP)
Autonomic and short-term
on-line optimizations
Local Optimization
Policies (LCP)
Given:
- the actual traffic workload
from input links
- Local service requirements
Dynamically find the best energyaware configuration
Routing & Traffic Engineering
Given:
- The traffic matrix
- Service requirements
- The energy-aware capabilities of network
nodes and links
Dynamically move the traffic flows among network
nodes in order to minimize the overall network
consumption
Operator-driven long-term
off-line optimizations
OAM
Given the history of measurements
regarding:
- network performance
- energy consumption
The operator can explicitly plan and/or
reconfigure the settings of:
- single device
- traffic engineering and routing.

Project current status
› A detailed analysis of traffic characteristics and
energy consumptions of the telecommunication
operators involved in the project has been finalized.
› A set of benchmarking methodologies and
performance indexes has been defined.
› 13 physical prototypes of different network devices (or
parts of devices) have been finalized. Each one provides
basic HW/FW capabilities for realizing dynamic
consumption modulation and/or advance standby modes.
› A detailed definition of the Green Abstraction Layer has
been almost completed (now a set of specific realizations
is under development for the above prototypes).
› The definition of local and distributed policies for the
optimization of the energy consumption with respect to
QoS constraints and incoming traffic load is currently in
progress.

Green Abstraction Layer
› Main objective: standardize the interface between the
Network Control Protocols (NCP, for the energy efficiency
purpose) and the power management capabilities of the
network devices.
› Problem:
– Energy consumption lies in the physical components (hardware)
– The largest part of network control protocols generally work on the
top of logical resources (e.g., IP/OSPF over MPLS, SDH, WDM, …)
– But a logical link has no direct power management capabilities,
given its logical and not physical nature. Only physical elements can
adopt different power settings.

Standardization current relevant activities
› The Green Abstraction Layer has been presented in the
ETSI EE WorkShop in June and, at the end of September, a
new Work Item for the standardization of GAL has been
approved (supported by ECONET and with Prof. Bolla as
rapporteur) in the ETSI EE TC.
› Moreover the activities related to the Network Connectivity
Proxy for the effective exploitation of the standby status of
the home devices (studied by ECONET and developed in the
home-gateway) has been proposed for the insertion in a
deliverable of the Home Gateway Initiative (HGI).
› Proposal for future step  standardization of GAL within
ITU-T (specific SG to be identified)
