    Abstract: A network function virtualization (NFV) orchestration service includes a centralized orchestration device and a multi-cluster container management (MCCM) platform. The centralized orchestration device stores a catalog of virtual network function descriptors (VNFDs) in an input language; generates, based on the catalog of VNFDs, intents for containerized network function (CNF) services; and stores the generated intents as blocks in a central intent database, wherein the blocks include an input data model for the CNF services. The MCCM platform includes one or more processors to receive and store a copy of the intent database; read design time policies from the copy of the intent database; and convert the input data model into a vendor-specific output data model in an output language.

    Abstract: A system described herein may provide a technique for the resolution of requests for Internet Protocol (“IP”) addresses for Virtualized Network Functions (“VNFs”) in a network, such as a Software-Defined Network (“SDN”) (e.g., a wireless telecommunications network). In the network, different instances of the same VNF may be implemented by different hardware resources, and may accordingly have different IP addresses. Metrics of routes between instances of a requested VNF type and a requestor may be calculated, and a particular instance of the requested VNF may be selected based on the metrics (e.g., a lowest cost, highest performance, etc.). The IP address of the particular VNF instance may be provided to the requestor. The requestor, such as a User Equipment (“UE”), may communicate with the particular VNF instance in order to receive services provided the requested VNF type.

    Abstract: A system described herein may provide a technique for the seamless failover of devices in a network, such as a wireless telecommunications network. For example, embodiments may identify a particular device, such as a Call Session Control Function (“CSCF”), that has failed or that does not meet particular performance metrics. An Internet Protocol (“IP”) address of the failed device may be assigned to a functioning device of the same type (e.g., another CSCF). The functioning device may be instructed, in accordance with some embodiments, to output routes between itself and other devices or IP addresses, based on which traffic originally intended for the failed device may be routed to the functioning device.
