Original Abstract Submitted
Techniques are described for classifying packet flows to different paths of a computer network based at least in part on an energy cost of each of the different paths. In one example, a network device determines a weighted equal-cost multipath (wECMP) cost of each of different paths over which to forward packets. The different paths may include, for example, different interfaces of a network device, different links to which the network device is connected, or different links of an aggregated bundle of Ethernet links. The network device determines an energy cost of each of the paths. The network device modifies the wECMP cost of each path based at least in part on the energy cost of the path to obtain a modified wECMP cost. The network device load balances the packets over the paths in accordance with the modified wECMP cost.
