1. A method comprising:
computing, by a computing system having a model of a multi-layer network, a total usage of a metric by each link of all paths of a first multipath provisioned in a network layer of the multi-layer network, wherein the first multipath is computed and placed to a model of the network layer in a first order;
computing, by the computing system, a total usage of the metric by each link of all paths of a second multipath that is computed and placed to the model in a second, different order; and
in response to determining that the total usage by the second multipath is less than the total usage by the first multipath, provisioning, by the computing system, the second multipath in the network layer.
