Providing hierarchical traffic engineering for a network

An ingress network device, comprising:

• one or more memories;
• and
• one or more processors to:
• calculate entry paths from across an entry network of a network,
• wherein the network includes a transit network with a plurality of transit network devices and a destination network with a plurality of destination network devices;
• store the entry paths locally in the ingress network device;
• receive traffic destined for a destination;
• retrieve, from a distributed data structure, transit paths associated with the transit network and destination paths associated with the destination network,
• wherein the distributed data structure is configured to store the transit paths, administrative policy properties of the transit paths, bandwidth utilization by the transit paths, the destination paths, administrative policy properties of the destination paths, and bandwidth utilization by the destination paths;
• determine a path for the traffic based on the entry paths, the transit paths, and the destination paths;
• and
• provide the traffic to the destination via the path.

A non-transitory computer-readable medium storing a set of instructions, the set of instructions comprising:

• one or more instructions that, when executed by one or more processors of an ingress network device, cause the ingress network device to:
• calculate entry paths from across an entry network of a network,
• wherein the network includes a transit network with a plurality of transit network devices and a destination network with a plurality of destination network devices;
• store the entry paths locally in the ingress network device;
• receive traffic destined for a destination;
• retrieve, from a distributed data structure, transit paths associated with the transit network and destination paths associated with the destination network;
• determine a path for the traffic based on the entry paths, the transit paths, and the destination paths;
• signal the path to one or more of the plurality of transit network devices and to one or more of the plurality of destination network devices;
• and
• provide the traffic to the destination via the path and based on signaling the path to the one or more of the plurality of transit network devices and to the one or more of the plurality of destination network devices.
