A communication device, processing device or method constructs M RLC PDUs including M RLC SDUs, respectively, where M is larger than 1; submits, for a transmission opportunity, only L RLC PDUs for L RLC SDUs with lowest L SNs among the M RLC PDUs to a MAC layer, where L<M and the L RLC PDUs include a first RLC PDU having a poll to trigger status reporting at a receiving device; transmits the L RLC PDUs to the receiving device; constructs a second RLC PDU including a second RLC SDU having a highest SN among SNs of RLC SDUs submitted to the MAC layer, when the poll retransmission timer started upon submitting the first RLC PDU having the poll expires and no new RLC SDU or RLC SDU segment can be transmitted.

An interworking service entity receives server registration requests including indications of service layer protocols used by each server, maintains a repository of server information, and uses the repository for interworking requests of devices to servers of different protocols based on a server type provided in discovery requests. Other matching information may include, for example, server security protocol, supported services, service territory, availability, capacity, or loading, as device information or preferences, such a supported service, supported interface type, or a supported device type.

An electronic device includes at least one wireless communication module at least one processor connected to the wireless communication module, and a memory connected to the processor and configured to store instructions executable by the processor. The processor is configured to, during transmission of a first data frame including first data through a first resource unit (RU) on a first time resource, in response to detecting second data being enqueued in a transmission queue, transmit a second data frame including the second data through a second RU on a second time resource overlapping the first time resource during the transmission of the first data frame, using the wireless communication module. The first data frame and the second data frame may be included in a physical layer protocol data unit, and a start time of the second time resource may be different from a start time of the first time resource.

A first fabric abstraction layer couples to a data link layer and a physical layer of a network fabric device. The network fabric device is connected to other network elements within a network via at least one network connection, such as a fiber optic connection. A second fabric abstraction layer couples to the data link layer and an application of the network device. The second fabric abstraction layer provides an application programming interface (API) to the application. The API allows the application to generate configuration instructions for configuring the at least one network connection. Upon receiving the configuration instructions generated by the application, the second abstraction layer sends the configuration instructions to the first abstraction layer via the data link layer. The first abstraction layer then configures the at least one network connection to transmit data according to the configuration instructions.

A novel design of a gateway that handles traffic in and out of a network by using a datapath pipeline is provided. The datapath pipeline includes multiple stages for performing various data-plane packet-processing operations at the edge of the network. The processing stages include centralized routing stages and distributed routing stages. The processing stages can include service-providing stages such as NAT and firewall. The gateway caches the result previous packet operations and reapplies the result to subsequent packets that meet certain criteria. For packets that do not have applicable or valid result from previous packet processing operations, the gateway datapath daemon executes the pipelined packet processing stages and records a set of data from each stage of the pipeline and synthesizes those data into a cache entry for subsequent packets.

A data transmission method and an apparatus are provided, to resolve a problem that network communication between a communications apparatus and an external network device cannot be ensured. A network protocol stack is deployed on both a wireless communications unit and a service processing unit, and the wireless communications unit is responsible for distribution. This can ensure processing of a network service and a throughput of a wireless network when a processing capability of the wireless communications unit is weak. The network protocol stack is deployed on the wireless communications unit. When the service processing unit is powered off, the wireless communications unit can still communicate with an external device, for example, remote wakeup.

Systems, apparatuses, and methods are described for wireless communications. A base station and wireless device may communicate capability information associated with a wireless device. The capability information may include information indicating support for an Ethernet type packet data unit session or header parameter compression. An Ethernet type packet data unit session may be instantiated based on the capability information.

A system for data communication between electronic devices comprises a first electronic device that is a resource-constrained device; and a second electronic device that exchanges data with the first electronic device. One of the first electronic device and the second electronic device generates a message in a data unit frame complying with a protocol stack that includes a Constrained Application Protocol (CoAP) message on a data link layer in the absence of a User Datagram Protocol (UDP) layer.
