1. A multi-path communication apparatus capable of improving energy efficiency comprising:
- a plurality of physical links;
a processor configured to select two or more physical links, that are included in an equal-cost multi-path for each packet destination, from among the plurality of physical links as path-links, generate and manage at least one destination-specific multi-path link group that includes the selected path-links as group members, and select path-links to which traffic is transmitted in a distributed manner from the destination-specific multi-path link group based on a traffic level of the destination-specific multi-path link group;
a traffic meter configured to measure a traffic level of path-links included in the destination-specific multi-path link group managed by the processor; and
a traffic splitter configured to distribute and transmit traffic heading for a destination of a corresponding multi-path link group to the path-links selected by the processor.

Abstract
The present invention relates to a multi-path communication device capable of improving energy use efficiency and a traffic distribution method for improving the energy use efficiency thereof, which can improve energy use efficiency of an entire network in multi-path communication by properly adjusting the number of paths for transmitting traffic according to traffic levels and distributing the traffic without distributing and transmitting the traffic to all possible paths.

16. A traffic distribution method of improving energy efficiency of a multi-path communication apparatus, comprising:
-
selecting two or more physical links included in an equal-cost multi-path as path-links for each destination, and generating at least one destination-specific multi-path link group that includes the selected path-links as group members; setting each path-link as an active path-link or idle path-link based on a priority of each path-link included in the destination-specific multi-path link group generated in the multi-path link group generating operation and initializing the path-link; measuring a traffic level of path-links included in the destination-specific multi-path link group; selecting active path-links to which traffic is transmitted in a distributed manner from among path-links of a corresponding destination-specific multi-path link group based on the traffic level of the destination-specific multi-path link group measured in the traffic measuring operation; and distributing and transmitting traffic to be transmitted to a corresponding destination to active path-links selected in the active path-link selecting operation.
