Abstract: In an example, a method includes computing, by a computing device, for a segment routing policy that specifies a bandwidth constraint for the segment routing policy, first shortest paths through a network of network nodes, wherein each shortest path of the first shortest paths represents a different sequence of links connecting pairs of the network nodes from a source to a destination; in response to determining, by the computing device based on the bandwidth constraint for the segment routing policy, a link of one of the first shortest paths has insufficient bandwidth to meet a required bandwidth for the link, increasing a metric of the link; computing, by the computing device, for the segment routing policy that specifies the bandwidth constraint, based on the increased metric of the link, second shortest paths through the network of network nodes; and provisioning the second shortest paths in the network of nodes.
