Abstract: When a virtualized service platform encounters a catastrophic fault, an orchestrator may instantiate new virtual machines instances to deploy additional capacity in other cloud locations to handle failover storms. After the network fault is fixed and service returns to normal condition, these additional VM instances may be removed from the platform and cloud resources may be released. The system may minimize the resource over-provisioning and may continue to support geographical redundancy or dynamic scaling in a large-scale service network.

Abstract: A method for vNF chaining management includes receiving virtualized network function (vNF) information from a chaining client associated with a particular vNF. A service chaining catalog is updated based on the vNF information and chaining information is transmitted to peering vNFs of the particular vNF. The vNF information can indicate instantiation of a vNF and identify peering vNFs. Updates received from vNFs can be used to update the chaining catalog. Updated vNF information can then be sent to peering vNFs of the vNF which sent the update.

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 method and apparatus for controlling a call volume for an office that serves as a protecting site for another office in a packet network are disclosed. For example, the method collects one or more customer registration counts from one or more session border controllers located in a first office, determines if the one or more customer registration counts have reached or exceeded a threshold. The method directs all of said one or more session border controllers located in said first office to enact one or more throttling rules if the one or more customer registration counts have reached or exceeded the threshold.

Abstract: Virtual machines may have external interfaces (E-VMs) and VMs with internal interfaces (I-VMs). A control system may automatically scale the quantity of I-VMs based on traffic demand, among other things.

Abstract: A method and apparatus for managing an overload condition in a network are disclosed. For example, the method monitors the network for a traffic overload condition, and determines whether a more severe traffic overload condition or a less severe traffic overload condition is detected by using a network monitor and controller. The method then selects using a network monitor and controller agent in response to a command from the network monitor and controller, a different bandwidth preservation scheme if the more severe traffic overload condition or the less severe traffic overload condition is detected, wherein the different bandwidth preservation scheme is based on a selection of a codec type and is applied to a portion of the traffic.

Abstract: A method and system for growing a next generation network (NGN) using a modular design are disclosed. For example, the method defines a growth core module to support a specific number of subscribers, wherein the growth core module is assigned a module identifier (ID). The method upgrades existing network entities that will be impacted by an installation of the growth core module in the existing IMS network, and installs the growth core module in the IMS network.
