Abstract: Systems, methods, and computer-readable media for interconnecting SDWANs through segment routing. A first SDWAN and a second SDWAN of a SDWAN fabric can be identified. A segment routing domain that interconnects the first SDWAN and the second SDWAN can be formed across a WAN underlay of the SDWAN fabric. Data transmission between the first SDWAN and the second SDWAN can be controlled by performing segment routing through the segment routing domain formed between the first SDWAN and the second SDWAN.

Abstract: Methods, systems, and non-transitory computer-readable media are provided for deploying intent-driving cloud branches. An example method can include obtaining, by one or more controllers in a software-defined network (SDN), a branch network design template for deploying a remote branch in the SDN, wherein the branch network design template defines networking settings for a plurality of services to be provisioned at the remote branch; obtaining, by the one or more controllers, a plurality of software packages for the plurality of services to be provisioned at the remote branch; and based on the branch network design template and the plurality of software packages, provisioning, by the one or more controllers, the plurality of services at the remote branch and a network connectivity of the plurality of services.

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: 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: The present disclosure is directed to systems and methods for dynamic firewall discovery on a service plane. The method includes the steps of identifying a source data packet for transmission from a source machine at a source site to a destination machine at a destination site, wherein the source data packet corresponds to a request for connection between the source machine and the destination machine over a WAN, inspecting the source data packet at a first firewall associated with the source site, marking the source data packet with a marker to indicate inspection by the first firewall, transmitting the marked source data packet to the destination site, determining at the destination site that the source data packet has been inspected based on the marker, and forwarding the source data packet to the destination machine at the destination site, without inspection of the source data packet by a second firewall associated with the destination site.
