    Abstract: Concepts and technologies are disclosed herein for providing a network virtualization policy management system. An event relating to a service can be detected, and virtual machines and virtual network functions that provide the service can be identified. A first policy that defines allocation of hardware resources to host the virtual machines and the virtual network functions can be obtained, as can a second policy that defines deployment of the virtual machines and the virtual network functions to the hardware resources. The hardware resources can be allocated based upon the first policy and the virtual machines and the virtual network functions can be deployed to the hardware resources based upon the second policy.

    Abstract: Concepts and technologies are disclosed herein for message flow management for virtual networks. A processor can identify a target virtual network function instance that is to be taken offline. The processor can change a status associated with the target virtual network function instance to indicate it being taken offline. The processor can start a graceful shutdown timer to trigger shutdown of the target virtual network function instance. The processor can identify external interfaces and a peer network function that identifies the target virtual network function instance as a next hop. The processor can obtain, for the target virtual network function instance and the peer network function instance, a snapshot that identifies configuration data for the target virtual network function instance and the peer network function instance and can generate a command to trigger a shutdown of the target virtual network function instance.

    Abstract: A mechanism controls global synchronization, or registration floods, that may result when a large number of endpoints in a Voice over Internet Protocol (VoIP) network such as an Internet Protocol Multimedia Subsystem (IMS) come online simultaneously after a catastrophic failure. The mechanism allows the Domain Name System (DNS) infrastructure to efficiently control the overload condition by registering user end points with backup border elements, and by staggering and by randomizing the time-to-live (TTL) parameter in registrations with backup border elements.

    Abstract: An example apparatus includes a memory and a call session controller. The memory is to store a first public user identifier in association with a first nomadic service designator and a first operating mode designator, and to store a second public user identifier in association with a second nomadic service designator and a second operating mode designator. The call session controller is to determine whether a first call using the first public user identifier is eligible to be established based on the first nomadic service designator and the first operating mode designator, and determine whether a second call using the second public user identifier is eligible to be established based on the second nomadic service designator and based on the second operating mode designator.

    Abstract: A mechanism is provided for recovering from a catastrophic failure that results in a large number of user endpoints attempting to come on line simultaneously after an NGN is restored. In an enhanced DNS load balancer, DNS queries from the user end points relating to a particular NGN edge device are selectively dropped if a rate of queries for the particular edge device suddenly increases or exceeds a threshold. The query dropping may also be based in part on the class of service assigned to the user endpoint.
