Abstract: A virtual network manager system comprising a server in communication with a node, the server including at least one virtual network function (VNF), a cluster manager in communication with the server, the cluster manager is configured to detect a change in a health of the VNF on the server and when the change in the health of the VNF occurs generate a signal to a node to perform an action, the action including at least one of throttling traffic to the VNF, rerouting traffic to an alternate VNF, changing a weight value for traffic to the VNF, and generating an alert indicating a relative capacity change at the VNF.

Abstract: Automated offloading of subscribers in a system having a set of mobility management entities (MMEs) during mobility management equipment failures is provided. Each MME maintains performance status and location information about all MMEs. When an MME senses performance degradation the traffic directed to that MME is allocated among the remaining MMEs in the set.

Abstract: The described technology is generally directed towards automated acceptance testing of network functions so that only certified network functions are deployed in a wireless network. When a network function attempts to register in a network, e.g., with a network function repository, the registration attempt triggers a workflow that obtains a result of automated testing of the network function. The automated testing operation can be based on a test suite selected according to the network function type and the network slice in which the network function is to be deployed. Only upon determining that the network function passed the automated testing operation is the network function registered (by the network function repository) for operation in the wireless network.
