Abstract: Systems and methods are provided for performing a live upgrade process of one or more devices (e.g., access points (APs), etc.) in a large scale network environment. For example, the system can use neighbor path loss data between the APs. The neighbor path loss data may identify the signal strength between two points as an indication of the ability to transmit power and receive power from the individual APs. When the ability to transmit and receive power is present in one AP is unavailable the user device may connect to a second AP to avoid losing connectivity. This neighbor path loss data may be utilized to perform a live upgrade process of APs in parallel at multiple locations of the user site.

Abstract: Systems and methods are provided for reducing WAN bandwidth consumption used by multicast for large scale software-defined branch deployments. In particular, a cloud-based multicast orchestrator may be implemented as part of an SD-WAN service. This cloud-based multicast orchestrator may orchestrate routes for multicast traffic between a multicast source and the various branches of the large scale software-defined branch deployment. This cloud-based multicast orchestrator may orchestrate routes for multicast traffic which reduce/optimize WAN bandwidth consumption. In combination with the cloud-based multicast orchestrator, examples may utilize a branch gateway hierarchy which designates one branch gateway a “leader” for a given multicast stream to further reduce WAN bandwidth consumption used by multicast.

Abstract: Examples relate to seamless roaming across subnets. In an example, a system receives an indication that a client device has been authenticated at a first network device of a network. The system receives precursor keys and identification information of the client device, as generated from the authentication of the client device. The system determines second clusters, which are within a roaming domain of the cluster or the client device. The system receives one or more second precursor keys corresponding to the second clusters and distributes the second precursor keys to the corresponding second clusters. The system determines to create one or more tunnels among the second clusters and the cluster and provisions the tunnels to transmit data through the tunnels.
