Optimized power usage for data networks
First Claim
1. A computer implemented method comprising:
- at a network device coupled to a network, examining traffic usage information of the network and power usage information of a plurality of routers in the network;
calculating a path from a first router of the network to a second router of the network based at least in part on the traffic usage information and the power usage information, the calculated path having relatively low aggregate power usage for routers comprising the path; and
storing an indication of whether one or more of the plurality of network routers may be placed in a power conservation mode based at least in part on the calculating.

Abstract
A solution for optimized power usage for a data network includes, at a network device coupled to a network, examining traffic usage information of the network and power usage information of a plurality of routers in the network, and calculating a path from a first router of the network to a second router of the network based at least in part on the traffic usage information and the power usage information. The calculated path has relatively low aggregate power usage for routers comprising the path. The solution also includes storing an indication of whether one or more of the plurality of network routers may be placed in a power conservation mode based at least in part on the calculating.
