Power Saving-oriented Path Reallocation Utilizing Advantage of Low Power Idle

Multi- (layer, path, and resources) Dynamically Optimized Routing (MiDORi) network which aggregates traffic by Traffic Engineering (TE) and reduce power consumption by on / off of port-by-port of network equipments have been proposed. Energy Efficient Ethernet (EEE) to perform the power reduction of the link as a related study has been attracting attention in recent years, technology called Low Power Idle (LPI) is adopted as a mechanism for power saving techniques EEE. However, the problem is that a power consumption using a conventional MiDORi algorithm at low traffic is increased in MiDORi network using LPI. Therefore, we propose a network power-saving technique by path re-allocation algorithm that takes into account the LPI power characteristics in this paper. By changing the path to a high link-usage link from a low link-usage link, it is a technique for reducing power consumption in the entire network. The comparison in terms of computation time, network performance and power consumption is performed for conventional method and proposed method, and confirmed the validity.
