Abstract: The present invention provides apparatuses, methods, computer programs, computer program products and computer-readable media regarding Ultra High-Speed Mobile Network based on Layer-2 Switching. Certain aspects of the present invention include receiving, at a first gateway, a data packet from a first host served by the first gateway destined to a second host served by a second gateway, the data packet having a header comprising a layer 3 destination address of the second host and a broadcast layer 2 destination address, searching, by the first gateway, a flow table stored in the first gateway for an identity of the second gateway associated with the broadcast layer 2 destination address, if the identity is found in the flow table, replacing the broadcast layer 2 destination address with the identity of the second gateway serving the second host, and transmitting the data packet to the second gateway.

Abstract: A method includes decomposing functionalities of an node, such as an edge node, of a mobile core domain of a wireless communications system into a plurality of partitions comprised of at least one application part for executing at least signaling plane functions and that interfaces logically to other signaling entities, at least one control part for executing at least transport functions and at least one network element part for executing at least data forwarding functions. The method further includes virtualizing the at least one application part and configuring at least one network element to perform at least one data forwarding function under the direction of the at least one control part. The control part is instantiated as at least one software-defined networking (SDN) controller, and the at least one network element includes a plurality of SDN controller configurable ports to receive data and to send data, and to also perform operations on received data such as tunnel termination/origination, encryption/decryption, traffic shaping and other needed user plane transport functions. The use of the invention enables a complete virtualization of the mobile core domain to be accomplished.

Abstract: Methods, apparatuses, and computer program products are provided in accordance with example embodiments for providing a combined service discovery and connection setup for a fifth-generation (5G) service-based architecture (SBA), and particularly for streamlined provisioning of services associated with a network repository function (NRF) from network function (NF) service providers to NF service consumers. In some embodiments, the NRF can register NF service providers by, at least, identifying supported transport layer network protocols (TLNPs) and then identifying for the NF service consumer only services associated with NF service providers supporting the same TNLP so that a further suitability handshake between the NF service consumer and the NF service provider is not required. In some embodiments, initial authentication of the NF service consumer by the NRF under a cryptographic protocol can be used as preauthorization for direct communication and service provisioning between the NF service provider and the NF service consumer, without requiring secondary authentication.

Abstract: A method and apparatus may include providing a multi-dimensional descriptor to a network function. The method may also include accessing a network slice. The network slice is selected based on the multi-dimensional descriptor. The method may also include accessing a component of the network slice. One or more network functions of the network slice are selected based on the multi-dimensional descriptor.
