Abstract: This disclosure describes techniques and mechanisms for disclosure describes techniques and mechanisms for a central management plane to automatically create and assign system identifiers to network devices, thereby creating a global network hierarchy within a network. The techniques enable the use of a system identifier to be automatically generated and assigned, as well as configuration and network policies to be automatically generated based on the system identifier. Accordingly, the techniques enable automation of regional connectivity and policy application, a simplified manner of troubleshooting/debugging of any connectivity issues, and a simplified, aggregated view of statistic and analytics related to problems at site, sub-region, and region levels.

Abstract: Systems and methods for managing traffic in a hybrid environment include monitoring traffic load of a local network to determine whether the traffic load exceeds or is likely to exceed a maximum traffic load, where the maximum traffic load is a traffic load for which a service can be provided by the local network, based on a license. An excess traffic load is determined if the traffic load exceeds or is likely to exceed the maximum traffic load. One or more external networks which have a capacity to provide the service to the excess traffic load are determined, to which the excess traffic load is migrated. The local network includes one or more service instances for providing the service for up to the maximum traffic load, and the service to the excess traffic load is provided by one or more additional service instances in the one or more external networks.

Abstract: A network controller can register WAN edge routers and WAN optimizers distributed across a WAN. The controller can receive a request to establish a WAN optimized connection between first and second hosts. The controller can identify a first WAN optimizer to perform first services (e.g., de-duplication, compression, application acceleration, caching, etc.) for first traffic from the first host to the second host and first complementary services for second traffic from the second host to the first host, and a second WAN optimizer for the second traffic and second complementary services for the first traffic. The controller can establish the optimized connection comprising a first path including the first host, WAN optimizer, and router; a second path including the first router and a second router, and a third path including the second router, WAN optimizer, and host. The controller can route the first and second traffic through the optimized connection.

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.
