Abstract: A device provides path data associated with a network that includes network devices interconnected by links. The path data includes data identifying a first path and a second path to be provided through the network. The device provides an instruction to cause the network devices to provide information identifying the first path and to route traffic via the first path, and receives an indication of a failure associated with the first path. The indication causes the network devices to provide information identifying the second path and to re-route the traffic from the first path to the second path. The device causes the failure associated with the first path to be repaired while the traffic is re-routed to the second path, and provides, based on causing the failure to be repaired, another instruction to cause the network devices to route the traffic via the first path.

Abstract: A device receives topology data and path data associated with a network that includes network devices. The device determines planned bandwidths for new paths through the network based on the topology data and the path data, and ranks the new paths, based on the planned bandwidths, to generate a ranked list. The device selects information identifying a first new path from the ranked list, wherein the first new path includes a first planned bandwidth. The device determines whether the first new path can be provided via a single route through the network based on the first planned bandwidth, and identifies two or more routes through the network for the first new path when the first new path cannot be provided via the single route. The device causes the first planned bandwidth to be reserved by two or more of the network devices for the two or more routes.
