Abstract: One embodiment provides selectively routing Domain Name System (DNS) request for sub-domains associated with a first network through a tunnel associated with the first network via the interface. DNS requests for sub-domains associated with a second network are selectively routed through a tunnel associated with the second network via the interface. Embodiments include replacing the destination address for DNS requests for sub-domains associated with the second network to match an address of a DNS server associated with the second network. Data representative of DNS requests for sub-domains associated with the second network is stored. Embodiments forward the DNS requests for sub-domains associated with the second network with the address of the DNS server associated with the second network.

Abstract: In an example embodiment, a method of dynamically tunneling specific, or per application, services on demand without having to build complex split tunneling policies on Virtual Private Network (VPN) terminators. In particular embodiments, the method can allow for tunneling to multiple data centers on devices with limited, e.g., single, concentrator capabilities.

Abstract: In one embodiment, an illustrative method herein may comprise: obtaining, by a device, one or more independent telemetry streams, wherein each of the one or more independent telemetry streams is uniquely identifiable by a span identifier; translating, by the device, each of the one or more independent telemetry streams into a corresponding QUIC protocol stream; mapping, by the device, the span identifier of each of the one or more independent telemetry streams to a respective stream identifier that uniquely identifies a QUIC channel of a multiplexed QUIC protocol stream; and communicating, by the device, the multiplexed QUIC protocol stream containing each of the one or more independent telemetry streams on its corresponding QUIC channel to cause a retrieving device to determine the span identifier of each of the one or more independent telemetry streams based on their respective stream identifier.

Abstract: In one embodiment, a device obtains telemetry regarding processor hardware of a compute node in a containerized system, whereby the telemetry has been converted into a common data format. The device associates the telemetry with a microservice of an application executed by the compute node. The device generates, based on the telemetry, a control flow graph for the microservice associated with the telemetry. The device provides an alert for display based on the control flow graph for the microservice.
