Abstract: The present technology discloses methods, systems, and non-transitory computer-readable storage media for establishing a redundant path connection. An example method can include configuring a software-defined wide-area network (SDWAN) tunnel between an on-premises router and a plurality of SDWAN routers; configuring a virtual layer 2 connection between the plurality of SDWAN routers and handoff locations for a virtual cloud resource (VCR) associated with at least one VCR tag, wherein a software-defined cloud infrastructure (SDCI) underlay associated with at least one SDCI provider connects to a cloud service provider (CSP) at the handoff locations; configuring a VCR connection between at least one VCR associated with the VCR tag and the handoff locations for the at least one VCR; configuring a border gateway protocol (BGP) session between the plurality of SDWAN routers and the handoff locations; and validating the SDWAN tunnel, the virtual layer 2 connection, the VCR connection, and the BGP session.

Abstract: The present technology is directed to controlling and managing resources both in Software-Defined Cloud Interconnect (SDCI) providers and cloud service providers via a single network controller and further connecting virtual networks in a branch site to virtual networks in the cloud service providers. A network controller can establish a network gateway in an SDCI provider, establish a cross-connectivity between the network gateway in the SDCI provider and one or more clouds, group one or more virtual networks in the one or more clouds and one or more virtual networks in a branch site into a tag, and establish a connection between the one or more virtual networks in the one or more clouds and the one or more virtual networks in the branch site using the tag.

Abstract: The present technology is directed to controlling and managing resources both in Software-Defined Cloud Interconnect (SDCI) providers and cloud service providers via a single network controller and further connecting virtual networks in a branch site to virtual networks in the cloud service providers. A network controller can establish a network gateway in an SDCI provider, establish a cross-connectivity between the network gateway in the SDCI provider and one or more clouds, group one or more virtual networks in the one or more clouds and one or more virtual networks in a branch site into a tag, and establish a connection between the one or more virtual networks in the one or more clouds and the one or more virtual networks in the branch site using the tag.

Abstract: Techniques for sharing the probing of software-as-a-service clouds among a cluster of routers are described herein. The techniques may include establishing a first path between a cluster of routers and an application infrastructure. Establishing a second path between the cluster of routers and the application infrastructure. Designating a first router in the cluster of routers to send probes over the first path to the application infrastructure. Designating a second router in the cluster of routers to send probes over the second path to the application infrastructure. Distributing, by the first router and to the cluster of routers, first routing performance data indicating a performance of the first path when communicating with the application infrastructure over the first path, distributing, by the second router and to the cluster of routers, second routing performance data indicating a performance of the second path when communicating with the application infrastructure over the second path.

Abstract: Techniques are described for routing traffic through an interconnect cloud gateway based on cloud traffic routing indicators. The interconnect cloud gateway can advertise the cloud traffic routing indicators, which can include cloud indicators and transport gateway indicators. The cloud indicators can include cloud tags utilized to route cloud traffic. The transport gateway indicators can include transport gateway flags utilized to identify private networks utilized to route the cloud traffic. The cloud traffic can routed during normal private network operation through private networks, which can be dynamically replaced by public networks due to occurrences of failures preventing the data traffic from being routed through the private networks and to cloud networks.
