Objectives:
- Introduce novel energy-aware metrics, weights and states for links and nodes to be exposed to routing and traffic engineering algorithms for traffic paths optimizations. These parameters will be derived from the definitions of T4.1.
- Study innovative algorithms for the distributed and dynamic optimization of network energy efficiency, which will be based on the previously defined metrics, and which will be devoted to be integrated in traffic engineering frameworks for backbone networks (i.e., metro, transport and core levels) in the context of MPLS protocol families, and according to the green extensions of signalling messages as defined in T5.4. Here, the base goal of these algorithms will consist of acting at the control-plane processes of each network node in order to realize a network-wide distributed optimization of power consumption.
- Design and develop novel traffic engineering strategies in order to re-routing traffic through the network and by optimally and dynamically exploiting the energy-aware capabilities of devices (i.e., both standby and power scaling). The objectives of these strategies will consist in reducing overall energy waste of nodes in a same network, while at same time meeting the network operational constraints in terms of end-to-end QoS, and fault-tolerance.
- Provide a first validation of the distributed and dynamic optimization strategies through simulation and/or emulation means.
- Enable the above routing suites to communicate with the green abstraction layer, by developing the interfaces specified in T4.2.
