A method for providing control plane encryption in layer 3 networks is disclosed. The method for providing control plane encryption in layer 3 networks includes for a network having a subset of network elements forming a secured domain; the steps of at a network element which is in the secured domain, encrypting all unencrypted Layer 3 packets as they egress an encryption enable egress interface; unencrypting all encrypted Layer 3 packets as they egress an egress interface is not enabled for encryption; and leaving encrypted all encrypted Layer 3 packets as they egress an encryption enable egress interface. A system and machine readable storage media are also disclosed.

Control plane encryption in IP/MPLS networks

Various embodiments relate to a communications system and related method of advertising available bandwidth capacities of leased links. After leasing a link to an operator device, a provider or operator may monitor the available capacity of the leased link and generate an advertising frame when the actual available capacity is below the defined leased capacity of the link. The advertising frame may be an L2 Ethernet frame in a form similar to the routing protocol used in the communications network to avoid additional strain and complexity in the network due to additional protocols for traffic engineering. After propagating the new information throughout the network using the advertising frame operator devices may redirect or shape their traffic of data in response to the updated available capacity on the leased link.
