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: The present disclosure is directed to managing industrial internet of things end points and includes one or more processors and one or more computer-readable non-transitory storage media coupled to the one or more processors and comprising instructions that, when executed by the one or more processors, cause one or more switches to perform operations comprising: identifying a first end point using a protocol associated with the first end point, determining a classification for the identified first end point based on one or more attributes of the first end point, identifying one or more related end points having the classification in common with the first end point, segmenting the first end point with the identified one or more related end points, and applying one or more policies to the segmented first end point and the one or more related end points.

Abstract: Techniques are presented in which a new information element signaling priority of a management entity is included in a setup (e.g., S1-Setup) response or configuration update message sent by a management entity to a base station entity. The base station entity interprets this priority information along with the relative capacity information in an appropriate way to load-distribute the traffic/calls to highly preferable management entity instances (at a local site) when they are available, and switchover/failover to lower preference management entity instances (at a remote site) when there is a local site outage/failure or insufficient capacity in a geo-resilient pooled network.

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.

Abstract: In one embodiment, a method by a first network apparatus includes receiving a request to access a resource from a client device associated with a user, determining that the request does not comprise a session cookie, sending an authorization request to a second network apparatus, receiving an authorization response including a resource authorization token from the second network apparatus, determining that the user is authorized to access the resource using the client device based on the received resource authorization token, establishing a first communication session with the client device by sending a message to the client device, and establishing a second communication session with a resource server that provides the resource, where the first network apparatus relays traffic between the client device and the resource server.

Abstract: A first virtual machine executing on a centralized management node provides a first image file to a first computing entity arranged within a first point of delivery. The first image file includes a first boot configuration file or a first ramdisk file. A second virtual machine provides a second image file to a second computing entity arranged within a second point of delivery different from the first point of delivery. The second image file includes a second boot configuration file or a second ramdisk file. The first virtual machine provides a third image file to the first computing entity. The third image file comprises a first operating system installation file. The second virtual machine provides a fourth image file to the second computing entity. The fourth image file comprises a second operating system installation file.

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.
