Techniques are described for routing traffic through an interconnect cloud gateway based on cloud traffic routing indicators. The interconnect cloud gateway can advertise the cloud traffic routing indicators, which can include cloud indicators and transport gateway indicators. The cloud indicators can include cloud tags utilized to route cloud traffic. The transport gateway indicators can include transport gateway flags utilized to identify private networks utilized to route the cloud traffic. The cloud traffic can routed during normal private network operation through private networks, which can be dynamically replaced by public networks due to occurrences of failures preventing the data traffic from being routed through the private networks and to cloud networks.

This application relates to a communication method, apparatus, and system. One example method includes: a first terminal device initiates RRC reestablishment in a first manner when determining that a second terminal device cannot continue to provide a relay service to the first terminal device, where the first manner is determined based on first information, and the first manner is a manner of initiating RRC reestablishment through a Uu interface, a manner of initiating RRC reestablishment through a new terminal device, or a manner of initiating RRC reestablishment through the second terminal device.

An example method of selecting message routing providers based on message delivery data reported by multiple customers includes: identifying a plurality of message routing providers serving a specified destination network; receiving, from a plurality of message originating entities, message delivery data reflecting message delivery by the plurality of message routing providers to the specified destination network; estimating, based on the message delivery data, for each message routing provider of the plurality of message routing providers, a corresponding message conversion rate reflecting a likelihood of successful message delivery by a respective message routing provider to the specified destination network; receiving one or more messages from a message originating entity that has not provided at least part of the message delivery data; and identifying, based on message conversion rates for respective message routing providers, one or more message routing providers for routing the one or more messages to the destination network.

Embodiments provide techniques for providing return-link routing in a hybrid communications network that includes a number of different networks having different characteristics. User terminal routing systems (UTRSs) provide interfaces between local user networks and the multiple communications networks of the hybrid network. Each UTRS can include a routing table having stored mappings that are populated according to forward-link communications (implicitly or explicitly), each associating a respective one of a plurality of routing table entries with one of the communications networks. When a UTRS receives return-link data from its respective local user network, the received data indicates a destination node. The UTRS can determine which of the stored mappings corresponds to the destination node and can route the received return-link data over a selected one of the communications networks in accordance with the identified one of the mappings.

A network device includes a plurality of network interfaces configured to couple with a plurality of physical network links. A packet processor is configured to process packets received via the plurality of network interfaces. The packet processor includes a path selection engine that is configured to: for each of at least some packets processed by the packet processor, successively make path selection decisions that correspond to respective routing domains within a hierarchical communication network, the path selection decisions for forwarding the packet through the hierarchical communication network.

Embodiments of the present application relate to a network slice allocation method, a terminal and a storage medium, and belong to the field of communications. The method includes if it is monitored that an application program is in a running state, determining an application type to which the application program belongs; and selecting at least one network slice from network slices corresponding to the application type, and allocating the at least one network slice to the application program; and the network slices corresponding to the application type refer to the network slices which are matched with the application type in advance.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to receive, from a distributed unit (DU) associated with a first radio access technology (RAT) of a radio access network (RAN), control information indicating a core network service offered by a service-based network associated with a second RAT. The UE may transmit, via the first RAT, a service request indicating the core network service offered by the service-based network associated with the second RAT. The UE may receive, from the DU, control signaling indicating a service configuration for communicating with the core network service offered by the service-based network. The UE may then transmit, to the DU via the first RAT and in accordance with the service configuration, a service message including a payload associated with the core network service, the payload in a format associated with the second RAT.

A data distribution device for stably distributing specific data such as video data is provided. Video distribution device as a data distribution device includes video distribution unit as a specific data distribution unit, video distribution determining unit as a specific data distribution determining unit, and routing setting unit. When video distribution determining unit determines that video distribution unit is distributing video data as the specific data, and when the default route information has been acquired from a second communication device connected to a second network, routing setting unit holds the default route information without changing the default route.

A relay device is connected to an upstream network via a plurality of communication paths and relays communication between the upstream network and a downstream network. The relay device includes a control unit. The control unit acquires communication status of at least one of the plurality of communication paths. The control unit selects one of the plurality of communication paths depending on the communication status. The control unit is connected to the upstream network by using the selected communication path.
