Abstract: Symmetric networking techniques disclosed herein can be applied by gateway routers in cloud networks. The techniques can ensure that both outbound traffic received at a cloud from a branch device and return traffic directed from the cloud back to the branch device are processed by a same gateway router. The gateway router can use network address translation to insert IP addresses from an inside pool and an outside pool assigned to the router.

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: Techniques for providing a standardized interface that is configured to provide application developers with ways for interacting with different wide area network controllers. A standardized interface may include an application programming interface (API) server that can receive a connectivity request associated with an application that is to be hosted on an application orchestration system. The API server may determine, based at least in part on the connectivity request, a vendor network to be used by the application to send traffic to a remote service. Based at least in part on determining the vendor network, the API server may translate the connectivity request into a first format that is understandable by a controller of the vendor network. The API server may also provide the connectivity request in the first format to the controller of the vendor network such that a path through the vendor network can be determined.

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: A solution for selecting an optimal user Plane entity (with Control and User Plane Separation (CUPS)) per UE during seamless roaming. In one embodiment, a method is provide that is performed by a control plane entity in a mobile core network that supports inter public land mobile network (PLMN) roaming among two or more PLMNs. The method includes obtaining a create session request from an entity in a second PLMN to which a user equipment has roamed from a first PLMN; selecting a particular user plane entity among a plurality of user plane entities based on one or more user equipment related parameters; and establishing a session with the particular user plane entity to serve user plane traffic in the mobile core network for the user equipment.

Abstract: In one embodiment, a method includes onboarding, by an edge router, a first tenant from a network management system and determining, by the edge router, a mapping of a tenant identifier associated with the first tenant to a controller identifier associated with a controller. The method also includes reserving, by the edge router, a port number in a kernel for the first tenant and inserting, by the edge router, the tenant identifier into a first control packet. The method further includes communicating, by the edge router, the first control packet to the controller via an encrypted control connection during a first peering session. The first peering session shares the encrypted control connection with a second peering session.
