To construct energy optimal Internet, a new traffic engineering concept aggregating traffic into specific links and dynamically powering off interfaces of routers/switches should be introduced. This paper proposes a network topology design algorithm and examines link power management.

A network using minimum set of nodes and links that all communication data traffics among nodes can be carried while meeting the QoS requirements named MiDORi (Multi-(layer, path, and resources) Dynamically Optimized Routing) has been proposed. MiDORi network technologies that is composed of a low energy consumption network design tool (MiDORi path computation engine (PCE)), MiDORi Generalized Multi-Protocol Label Switching (GMPLS) protocol extensions for controlling network equipment, and a MiDORi router/switch controlled by MiDORi GMPLS, are now developing. This paper describes recent activities of the MiDORi network technologies.
