<p>A method and apparatus are provided for determining the power cost of transmitting packets along a specified path. A particular type of OAM packet is transmitted along the path by a first node, and each node along the path adds its power cost of transmitting packets to the OAM packet. Upon reaching the end of the path, the OAM packet is returned to the first node where the power cost of the total path is determined and stored in association with the path.</p> |
