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.

Abstract: In an example, a method comprises, by a computing device, in response to receiving an indication of a modified network topology for a segment routing (SR)-enabled network comprising one or more network nodes: determining whether an existing, first multipath in the modified network topology for the network satisfies a path computation deviation for a SR policy, wherein the path computation deviation is a deviation from an initial path computation constraint for the SR policy; when the first multipath in the modified network topology satisfies the path computation deviation for the SR policy, performing a recomputation policy action that is associated with the path computation deviation; and when the first multipath in the modified network topology does not satisfy the path computation deviation for the SR policy, computing a second multipath in the modified network topology for the network to satisfy the initial path computation constraint for the SR policy.

Abstract: Network elements are managed with a server to support client data models from heterogeneous data sources. A server receives a first query for configuration data of a network element to be returned in a first model. The server determines a model type for the configuration data of the network element. When the model type is a second model that is not the first model, the server sends a second query to the network element for the configuration data to be returned in the second model and transforms the configuration data received from the network element into the first model. Additionally, the server returns the configuration data in the first model as a response to the first query.

Abstract: Techniques are described for optimizing multipaths of a segment routing-enabled network. For example, a computing device is configured to: for each link in a network layer of a multi-layer network, compute a usage (metric) of the link by all paths of a first plurality of multipaths provisioned in the network layer to compute a total usage by the first plurality of multipaths, the first plurality of multipaths having been computed and placed to a model of the network layer in a first order; compute a second plurality of multipaths, wherein the second plurality of multipaths are computed and placed, to the model of the network layer, in a second, different order; and in response to determining that the total usage by the second plurality of multipaths is less than the total usage by the first plurality of multipaths, provision the second plurality of multipaths in the network layer.

Abstract: Techniques are described for computing lists of segment identifiers (SIDs) that satisfy each path in a multipath solution for a segment routing (SR) policy. In an example, a method includes obtaining, by a computing device, a plurality of paths through a network comprising one or more network nodes, each path of the plurality of paths representing a different sequence of links connecting pairs of the network nodes from a source to a destination; computing, by the computing device, one or more lists of segments identifiers (SIDs) that satisfy each path of the plurality of paths; and programming the network to forward network traffic based at least on the one or more lists of SIDs.
