In accordance with the example embodiments of the invention there is performing a communication including transmitting packets of a first traffic subflow and packets of a second traffic subflow via a first radio bearer to a second device; detecting that further packets of the second traffic subflow are to be transmitted via a second radio bearer to the second device; and based on the detecting, transmitting a packet data unit via the first radio bearer to the second device, wherein the packet data unit includes an indication of a switch of the second traffic flow to the second radio bearer, and wherein packets of the first traffic flow continues to be transmitted via the first radio bearer. In accordance with the example embodiments there is receiving from a first device a communication packets of a first traffic subflow and packets of a second traffic subflow via a first radio bearer; receiving from the first device a packet data unit including an indication that further packets of the second traffic subflow are to be received via a second radio bearer, wherein the first traffic flow continues to be received via the first radio bearer; establishing the second radio bearer between a second device and the first device; and based on the establishing, receiving the further packets of the second traffic flow via the second radio bearer.

An unmanned aerial vehicle manages storage of data and transfer between other connected devices. The unmanned aerial vehicle captures sensor data from sensors on the unmanned aerial vehicle. The unmanned aerial vehicle transfers the captured sensor data from the unmanned aerial vehicle to a remote controller via a wireless interface. The captured data may be transferred via a TCP link, a UDP link, or a combination thereof. If a loss of link is detected, the captured sensor data is stored to a buffer and a battery level of the unmanned aerial vehicle and a flight status of the unmanned aerial vehicle is monitored. The stored sensor data is transferred from the buffer to a non-volatile storage responsive to the battery level dropping below a predefined threshold or detecting that the unmanned aerial vehicle is stationary and a shutdown may be imminent.

A system for facilitating a plurality of virtual transmission control protocol connections between a target application and a source application is provided. The system includes a server proxy, a client proxy, and a network protection interposed between the server proxy and the client proxy. The server proxy is configured to receive an open request from the client proxy via a stateless protocol, including a target identifier, the open request originating from the source application, open a connection between the server proxy and the target application based on the target identifier, provide a response to the client proxy indicating a status of the open request, the response including at least one of a session identifier or a sequence identifier, receive, a data request from the client proxy, including the session identifier and an incremented sequence identifier, and provide the data request to the target application.

Exemplary embodiments include methods and/or procedures for handling messages from one or more data-plane nodes (DPNs) to a plurality of controller nodes configured in a cluster, comprising: receiving a message from a DPN; tagging the message with an incarnation identifier (IID) associated with the DPN; and performing HD handling of the tagged message, which includes comparing a value of the IID of the tagged message with a value of a global IID associated with the DPN, discarding the tagged message if the value of the IID of the tagged message is less than the value of the global IID, and processing the tagged message if the value of the IID of the tagged message is not less than the value of the global IID. Exemplary embodiments also include controller nodes, controller clusters, and computer-readable media embodying operations of the exemplary methods and/or procedures.

A method implemented by a session management function (SMF) network element and comprises receiving, from a terminal device, a first message requesting to establish or update a protocol data unit (PDU) session, and comprising first indication information indicating that the terminal device supports either a quick user datagram protocol (UDP) internet connection (QUIC) capability or a multi-path (MP) QUIC (MP-QUIC) capability, determining whether a traffic flow in the PDU session is transmitted using a QUIC method or an MP-QUIC method, and sending, to the terminal device, a second message indicating that the PDU session is successfully established or updated, and comprising second indication information indicating that the traffic flow is transmitted using the QUIC method or the MP-QUIC method.

A data transmission method includes establishing, by a first apparatus in a distributed system, a connection to a target end; sending, by the first apparatus, connection information of the connection to a second apparatus that is in the distributed system and that transmits data to the target end; transmitting, by the second apparatus, the data to the target end based on the connection information and using a stream of the connection.

A method for providing performance guarantees for using microservices in a cloud-native architecture is provided. A network service controller specifies a set of performance characteristics for a particular service that is accessible by a network. The network service controller identifies a particular path in the network for the particular service having a performance guarantee that meets the specified set of performance characteristics. The network service controller configures a host machine running virtualization software with forwarding information for the particular path. The forwarding information is used to tag the packet with a list of transit nodes associated with the particular path when a packet is to be forwarded for the particular service.

A method for transmitting data packets of at least one communication service from a first network entity to at least one destination network entity includes: establishing a quick user datagram protocol internet connection tunnel between the first network entity and a second network entity; transmitting the data packets from the first network entity to the second network entity via the quick user datagram protocol internet connection tunnel, wherein the data packets are encapsulated within quick user datagram protocol internet connection packets, and wherein the quick user datagram protocol internet connection packets are transmitted from the first network entity to the second network entity via multiple paths; extracting the data packets from the received quick user datagram protocol internet connection packets in the second network entity; and forwarding the extracted data packets from the second network entity to a respective destination network entity.
