Energy-aware routing in multiple domains software defined networks
The growing energy consumption of communication networks has attracted
the attention of the networking researchers in the last decade. In this context,
the new architecture of Software-Defined Networks (SDN) allows a flexible
programmability, suitable for the power-consumption optimization problem.
In this paper we address the issue of designing a novel distributed routing
algorithm that optimizes the power consumption in large scale SDN with
multiple domains. The solution proposed, called DEAR (Distributed Energy-
Aware Routing), tackles the problem of minimizing the number of links that can
be used to satisfy a given data traffic demand under performance constraints
such as control traffic delay and link utilization. To this end, we present
a complete formulation of the optimization problem that considers routing
requirements for control and data plane communications. Simulation results
confirm that the proposed solution enables the achievement of significant energy
savings.Peer ReviewedPostprint (published version
