Abstract: Some examples relate to distributing application classification entries to network devices. An example includes receiving, by a processing resource in a cloud computing system, an application classification entry for an application from respective network devices on a network. The application classification entry may comprise a given application identifier for identifying the application and control information for routing a network packet originating from the application. For the given application identifier, the processing resource may generate a consolidated set of application classification entries, based on the application classification entry received from respective network devices. The processing resource may then determine appropriate network devices to distribute the consolidated set of application classification entries.

Abstract: Systems and methods are provided for receiving an indication that controllers and network devices belong to a site of a network, detecting the controllers and the network devices at the site, clustering the controllers to be deployed in the network, mapping the network devices to the controllers, and tunneling traffic from client devices accessing the network through the network devices to one of the controllers.

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: Example implementation relates to a method of failure detection and seamless traffic switchover in a VPN system. A cluster of nodes exchange heartbeat messages to detect a failure at a first node in the cluster. When failure is detected at the first node, a master node transmits a failover message to a network end node connected to the first node. The failover message includes a list of active nodes to which traffic may be routed. The network end node updates its routing table based on the failover message and switches the traffic to a second node in the cluster of nodes.
