Abstract: Monitoring an operational characteristic of a data communication device within a network includes sampling an operational characteristic of the data communication device at a fine-grain sample rate over a first sampling interval to produce fine-grain samples of the operational characteristic of the data communication device, training a machine learning algorithm using the fine-grain samples of the operational characteristic of the data communication device, the fine-grain sample rate, and a coarse-grain sample rate that is less than the fine-grain sample rate, sampling the operational characteristic of the data communication device at the coarse-grain sample rate over a second sampling interval to produce coarse-grain samples of the operational characteristic of the data communication device, and using the machine learning algorithm to process the coarse-grain samples of the operational characteristic of the data communication device to produce accuracy-enhanced samples of the operational characteristic of the data communication device.

Abstract: Techniques are presented to stitch existing virtual private networks (VPNs), such as MPLS based VPNs, with virtual private clouds (VPCs) in public cloud data centers. The stitching architecture can be realized by configuring a virtual routing application (VRA) in the VPCs and configuring virtual routing applications and a virtual routing application controller in the existing VPN. For VPCs in public clouds that do not have a VRA, traffic can be default routed to VPCs with a VRA.

Abstract: A method for performing virtual private cloud (VPC) routing across multiple public cloud environments. In an embodiment, the method creates a first virtual routing agent (VRA) for a first VPC of a first public cloud. The method sends a registration request to a VRA controller, wherein the registration request comprises a data structure that includes communication parameters of the first VRA. The method receives the communication parameters of other VRAs for other VPCs located in other public cloud environments from the VRA controller. The method uses the communication parameters of the other VRAs for overlay routing of data packets from the first VPC of the first public cloud to other VPCs of other public clouds via the other VRAs of the other VPCs.
