Virtualization of control plane network elements

摘要

A system includes a first regional network including a first network element; a second regional network including a virtualized control plane network element, the virtualized control plane network element supporting a routing protocol at the first regional network, the routing protocol employing a location-based cost model; and a network connection connecting the virtualized control plane network element to the first regional network, the network connection having a network connection cost, the network connection cost applied in the location-based cost model to support the routing protocol at the first regional network.

1. A system comprising:
a first regional network including a first network element, the first regional network element including a provider edge router; a second regional network including a virtualized control plane network element, the virtualized control plane network element executing a routing protocol for the first regional network, the routing protocol employing a location-based cost model, the virtualized control plane network element providing an instance of a control plane network element for the first regional network; and a network connection connecting the virtualized control plane network element to the first regional network, the network connection having a network connection cost, the network connection cost applied in the location-based cost model to support the routing protocol at the first regional network; the first regional network comprising an area border router coupling the first regional network to a backbone level network; wherein the network connection connects the virtualized control plane network element to the area border router; wherein the network connection cost is assigned upon creation of the network connection; wherein the virtualized control plane network element is a control plane portion of a physical network element located in the first regional network.
