MiDORi (Multi-(layer, path, and resources) Dynamically Optimized Routing) is an innovative “network-sided” approach for power-saving networks. While convenient power-saving technologies are mostly focused on network equipments, MiDORi achieved to reduce power consumption from a different point of view; aggregate traffics by traffic engineering (TE) and power down unused links.
Toward the realization of power-saving network by MiDORi, four elemental technologies are developing; (1) network designing and routing algorithm to achieve minimum power consumption (MiDORi TE)， (2) fast computing engine (MiDORi Path Computation Element (PCE))， (3) dynamic link power on/off protocol (MiDORi GMPLS)，(4)prototype switch enabling port-based power on/off.
Gigabit ECO Layer-2 Switch
- Port power remote control:
Reduce energy consumption by powering OFF interface ports that are not used.
It is also possible to put the switch into sleep by powering OFF all interfaces.
- Energy consumption monitoring:
Constant energy consumption monitoring by on board ammeter.
- Traffic monitoring:
The number of transmitted/received packets are monitored at each interface port by remote connection.
