5 Vision and main research threads

6 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. The Network Operation Center (NOC)

7 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 Standard Interface (GSI) GAL Convergence Layer Interface (CLI)

8 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.

9 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)
