A multi-radio service of a provider network may be used to manage and route payloads for client edge devices that use multiple types of radios. The multi-radio service may associate different types of radio controllers with an edge device of a client, so that messages that are transmitted from different types of edge device radios can be handled by different radio controllers. A radio controller may receive a message and extract the payload from the message based on the data/data format specific to the radio protocol used to transmit the message. When a client-owned cloud application sends a payload to an edge device, the multi-radio service may select, based on criteria (e.g., fastest data transmission), the radio of the edge device from multiple available radios. The corresponding radio controller may then generate and send a message to the selected radio of the edge device (e.g., via a corresponding gateway).

Managing and routing payloads for client edge devices that use multiple types of radios

A system and method for securely sharing metadata among virtualized network functions (VNFs) disposed within a cluster of host computers includes a distributed forwarding and metadata sharing (DFMS) framework that forwards received data packets and provides remote direct memory access (RDMA) enabled sharing of secured metadata among the VNFs from more than one host computer in the cluster of host computers, and a DFMS controller that resides in the cluster of host computers as a VNF and registers VNFs in the cluster to at least one group of VNFs in the cluster and assigns access rights to the metadata of VNFs within respective groups of VNFs in the cluster. In operation, each registered VNF in a group in the cluster uses RDMA requests to access the metadata for other registered VNFs in the group in the cluster to which the each registered VNF in the group has access rights.

Secured metadata sharing among VNFs

An IoT service of a provider network may be used to provision edge devices with duplicate device identifiers for edge devices that use a radio communication protocol (e.g., LoRaWAN). This may allow a service provider to accept legitimate registration requests from edge devices instead of automatically rejecting them. When the IoT service receives a registration request, the service determines whether there are other devices registered with the same device ID. If so, then the service determines whether to accept or reject the request. For example, the service may determine whether the number of duplicate device IDs being used for registered devices will remain within a predefined threshold if the device is registered. If so, then the service registers the device. Otherwise, the service rejects the request.

Managing duplicate device identifiers for edge devices of client networks that use a radio communication protocol

According to one aspect of the present disclosure, there is provided a computer-implemented method for dynamically allocating edge computing resources. The method can include receiving, in an edge computing center, a request for using the edge computing resources to perform a secondary task for a secondary edge service, allocating the edge computing resources to the secondary edge service if the edge computing resources are available, and in response to an increase in a primary edge services workload, reallocating at least a portion of the edge computing resources from the secondary edge service to the primary edge services if the edge computing resources are insufficient for performing the primary edge services.

Systems and methods are provided for recognition of an application in communication traffic flow in a network using an artificial intelligence (AI) based hierarchical service awareness engine. A decode equivalent class (DEC) can be used to provide information on the application. A DEC corresponds to a class of traffic that is mapped to an artificial intelligence (AI) model associated with parameters related to the class of traffic. DEC information can be fed to an AI model set and an inference model can be derived from a AI model of the AI model set corresponding to a DEC. The inference model can be provided to a gateway of the network to recognize a specific application of a service in communication flows. In various embodiments, in training the AI models, the gateway can provide DEC information for the AI model set from classifying flows of data traffic received from the network into DECs.

Artificial intelligence based hierarchical service awareness engine

A protocol independent network condition service (PINCS) apparatus is provided, comprising a memory storage comprising instructions and one or more processors in communication with the memory. The processors execute the instructions to receive a subscription for network condition information of at least one network from at least one network condition consumer (NCC) node, the network condition information being related to at least one target data flow provided to at least one node in the network via the NCC node, obtain information about a plurality of network conditions from at least one network condition provider (NCP) node configured to monitor a plurality of network conditions including network conditions related to the at least one target data flow, process the information about the plurality of network conditions to generate an aggregated network conditions information, and send the aggregated network conditions information the NCC node as indicated by the subscription.

Method and apparatus for reducing network latency

Interruptions in communication due to user equipment (UE) handovers (HO) are signaled from the mobile communication network to the traffic source. For ultra-low latency and reliable communication, the signaling of HO start and completion notifications prevents retransmissions of in-flight packets by the traffic source, eliminating additional delays and inefficiencies. Signaling can be implemented by a network element, by a network element in conjunction with a smart traffic handler between the network and the traffic source (e.g., applications) and by a UE having at least two different radio interfaces.

For example, third and fourth generation wireless networks may benefit from a mechanism and apparatus to perform cooperative resource management, for example, for video downloads. Various methods are possible. For example, a method can include regulating fill and drain phases for a downloading session, to meet just in time delivery. The regulating can be performed by a user equipment based on parameters provided by a network. Another method can include providing parameters to a user equipment and instructing the user equipment with respect to regulating fill and drain phases for a downloading session, to meet just in time delivery, based on the parameters. A further method can include performing a mutual handshake between an application and a radio network regarding just in time delivery of a download.

Mechanism and apparatus to perform cooperative resource management in wireless networks

A method performed at an apparatus includes receiving a request for media content corresponding to a user equipment; requesting and receiving some of the media content from a server; and if the requested media content should not be optimized, sending, through the network toward the user equipment, information that causes a node to direct additional requests from the user equipment for the media content through the network toward the server without passing through the apparatus. Another method includes receiving a redirect message comprising an indication corresponding to a location of media content and comprising a tag indicating the redirect message should cause a first apparatus to redirect requests from a user equipment for the media content to a server having the media content without passing through a second apparatus; and for requests received from the user equipment and corresponding to the indication, forwarding requests through the network toward the server.

Techniques to support selective mobile content optimization

A heterogeneous wireless communication network includes a home access network with a home network characteristic and a home network policy, and a visiting access network with a visiting network characteristic and a visiting network policy. A packet data node gateway is adapted to communicate with the home access network and the visiting access network over a first communication path. An out-of-band communication path substantially separate from the first communication path is adapted to carry the visiting network policy from the visiting access network to the packet data node gateway. When the terminal is handed off from the home network to the visiting network, the packet data node gateway retrieves the visiting network policy, and the terminal accesses the visiting network over the first communication path using the visiting network policy.
