FILTERING TOPOLOGIES FOR PATH COMPUTATION IN MASSIVELY SCALED NETWORKS

Abstract:

An example network element includes one or more interfaces and a control unit, the control unit includes one or more processors configured to determine an egress network domain identifier (ID) and determine an abstracted interdomain network topology. The one or more processors are also configured to determine one or more interdomain paths from an abstracted ingress domain node to an abstracted egress domain node and determine whether an abstracted domain node is on the one or more interdomain paths. The one or more processors are configured to, based on the abstracted domain node being on the one or more interdomain paths, include one or more resources within a network domain in a filtered traffic engineering database (TED) and compute a path from an ingress node within the ingress network domain to an egress node within the egress network domain based on the filtered TED.
