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: A device receives border gateway protocol (BGP) data associated with links provided in a segment routing network. The segment routing network includes a first autonomous system (AS) with first network devices interconnected by a first portion of the links, a second AS with second network devices interconnected by a second portion of the links, and an inter-AS link provided between one of the first network devices and one of the second network devices. The device filters prefixes of the BGP data to identify BGP data associated with the inter-AS link, where the BGP data associated with the inter-AS link includes data identifying state information associated with the inter-AS link. The device determines an operational state of the inter-AS link based on the BGP data associated with the inter-AS link, and performs one or more actions based on the operational state of the inter-AS link.

Abstract: A device receives network data associated with a network that includes network devices interconnected by links, and receives constraints. The device determines potential network plans for the network based on the constraints and the network data, and identifies a potential network plan that minimizes costs associated with operating the network. The device aggregates the network data for the potential network plan to generate first aggregated data, and generates a first user interface based on the first aggregated data. The device provides the first user interface to a client device, and receives, from the client device, information indicating a first interaction with the first user interface. The device aggregates the first aggregated data, based on the first interaction, to generate second aggregated data, and generates a second user interface based on the second aggregated data. The device provides the second user interface to the client device.
