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: Route exchange in a plurality of network controller appliances on a per-tenant basis is disclosed. In one aspect, a method includes receiving, from a network management system and at a first network controller appliance, a designation of at least two tenants to be hosted on the first network controller appliance, the first network controller appliance being one of a plurality of network controller appliances in a SD-WAN; sending, from the first network controller appliance to other network controller appliances of the plurality of network controller appliances, a tenant list query message to obtain a corresponding tenant list of each of the other network controller appliances; and receiving a corresponding response from each of the other network controller appliances indicating the corresponding tenant list of each of the other network controller appliances, the corresponding response being used to update the tenant list on the first network controller appliance.

Abstract: Systems, methods, and computer-readable media for performing threat remediation through a switch fabric of a virtualized network environment. Data traffic passing into a virtualized network environment including a plurality of virtual machines running on a switch fabric is monitored. A network threat introduced through at a least a portion of the data traffic is identified at the switch fabric. One or more remedial measures are performed in the network environment based on the identification of the network threat in the virtualized network environment.

Abstract: An application monitoring system for collecting, utilizing, and/or exchanging state information (e.g., application state and network state), configuration information, and/or other information to make network optimizations for applications orchestrated by an application orchestration system. The application monitoring system may include an application orchestrator discovery component that is configured to determine a presence of an application orchestration system for orchestrating applications. The application monitoring system may also include one or more application watch components for monitoring, among other things, application state, application configuration, and/or application replicas. The application monitoring system may further include a network state propagation component configured to provide network state information to the orchestration system.

Abstract: According to some embodiments, a software defined wide area network (SD-WAN) includes a first region and a second region. The first region includes multiple first routing controllers and multiple first SD-WAN edge routers. The second region includes multiple second routing controllers and multiple second SD-WAN edge routers. Each first SD-WAN edge router of the first region is configured to establish Overlay Management Protocol (OMP) peering connections with the plurality of first routing controllers of the first region but to avoid establishing OMP peering connections with the plurality of second routing controllers of the second region. Each second SD-WAN edge router of the second region is configured to establish OMP peering connections with the plurality of second routing controllers of the second region but to avoid establishing OMP peering connections with the plurality of first routing controllers of the first region.

Abstract: In one embodiment, a method includes identifying, by a router, a first tenant. The first tenant is associated with a first tenant virtual private network (VPN). The method also includes determining, by the router, a mapping of the first tenant VPN to a first device VPN and generating, by the router, a first label representing the first device VPN. The method further includes adding, by the router, the first label to a first network packet and communicating, by the router, the first network packet with the first label to a controller.

Abstract: A method for allocating resources of a virtual controller is disclosed. The method comprises: allocating resources of a virtual controller to a first tenant, wherein the first tenant is allocated a first tenant quantity of guaranteed resources of the virtual controller and a second tenant is allocated a second tenant quantity of guaranteed resources of the virtual controller; determining that resources requested by the first tenant are greater than the first tenant quantity of guaranteed resources; determining that the virtual controller has unutilized resources sufficient to at least partially provide additional resources beyond the first tenant quantity of guaranteed resources to the first tenant; and temporarily provisioning the additional resources to the first tenant, wherein the additional resources are greater than the first tenant quantity of guaranteed resources.
