Abstract: A method implemented by a central controller is provided. The method includes receiving traffic monitoring information from a client, and sending a traffic monitor request to a network controller, the traffic monitor request requesting the network controller to monitor one or more traffic parameters based on the traffic monitoring information. The method further includes receiving a traffic report from the network controller, and responsive to determining that a monitored traffic parameter in the traffic report does not satisfy a condition specified by the traffic monitoring information, initiating a scaling operation based on data contained in the traffic report.

Abstract: A customer network controller (CNC) including a processor and a memory. The processor is configured to use a virtual private network (VPN)-specific service model for a VPN service and map the VPN-specific service model to one or more traffic engineering (TE)-specific parameters. The memory is coupled to the processor and configured to store a mapping between a VPN identification (ID) of the VPN service corresponding to the VPN-specific service model and a tunnel ID of either an existing TE tunnel or newly-established TE tunnel for the VPN service. The existing TE tunnel or the newly established TE tunnel satisfies the one or more TE-specific parameters.

Abstract: A method for establishing end-to-end tunnels extending across multiple domains using a network element. The method includes receiving a request from a customer controller to implement a virtual network (VN) created by the customer controller, wherein the VN identifies the end-to-end tunnels extending across the multiple domains, mapping the VN to available resources based on network constraints in response to the request, and transmitting, after the VN has been mapped, a message to a network controller managing one of the domains that includes a network path used to form a portion of one of the end-to-end tunnels, wherein the message includes an association object having a Type-Length-Value (TLV) field containing a virtual network identifier binding the network path to the VN.
