Embodiments of this application disclose a data transmission method, to reduce a delay. If a network device receives burst data, the network device preferentially sends the burst data. The burst data may be data whose data amount is greater than a data amount threshold.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for receiving from a plurality of publishers messages of a first channel of a plurality of distinct channels wherein each channel comprises an ordered plurality of messages, storing messages of the first channel in one or more first buffers according to the order, each first buffer having a respective time-to-live, for one or more connections, determining a respective sampling rate based on a data type of the first channel and a determined latency of the connection, receiving from a subscriber through a first connection a request for messages of the first channel, selecting messages in the first buffers according to the order and the sampling rate, and sending the selected messages using the first connection to the subscriber according to the order.

An apparatus with a data input, a data output, a first buffer, a second buffer, and control logic is disclosed. The control logic is equipped to route data packets that are received through the data input to the first buffer or the second buffer and to flag them as valid or invalid, and to provide data packets that are to be output through the data output from the first buffer or the second buffer, equipped to provide a data packet that is to be output through the data output from the first buffer when the data packet is being written into the first buffer at the time of a start of the readout, to provide it from the second buffer when the data packet is being written into the second buffer at the time of a start of the readout.

A method of processing received Packet Data Convergence Protocol (PDCP) data packets in a PDCP layer module of a telecommunications base station, includes receiving by the PDCP layer module a plurality of data packets, determining by an analysis module of the PDCP layer module a proportion of the data packets received out of sequence over a predetermined number of received data packets, setting an expiry time of a reordering timer of a buffering and reordering module of the PDCP layer module according to the proportion, and starting the reordering timer upon receiving an out of sequence data packet in which the out of sequence data packet is added to a reordering buffer of the buffering and reordering module. If the reordering timer reaches the expiry time, data packets are removed from the reordering buffer and transferred from the PDCP layer module to another layer module of the base station.

Systems and methods for data scheduling and queuing. A data network node is configured to transmit data in a store-and-forward fashion. The data network node includes a delay and validity determination module that determines and assigns a validity value to each data packet incoming via an input port based on a time stamp of the data packet, a current time value, an expected delay on a route of the data packet to its destination, and a packet urgency value. A scheduling module and a queue managing module execute their functions based on the validity value assigned to a data packet in a transmission buffer.

A multipath transmission control method oriented to deadlines of data blocks, includes: allocating transmission paths and timeslots to multiple data blocks to be sent at a sender according to heterogeneous attributes of the multiple data blocks and current network conditions, wherein the heterogeneous attributes comprise deadlines, sizes and priorities of the multiple data blocks; determining whether sending condition changes; and when the sending condition changes, rescheduling the multiple data blocks to be sent.

An electronic device is provided. The electronic device includes a network connection device, at least one processor, and a memory operably connected to the at least one processor, wherein the memory store instructions which are configured to, when executed, control the electronic device to receive a data packet from the network connection device, identify an Internet protocol (IP) type of a server, based on header information of the received data packet, identify information related to packet mergence set according to the identified IP type of the server and an IP type of the electronic device, and merge the data packets received from the network connection device or flush the data packets as a network stack, based on the identified information related to the packet mergence.

The invention relates to a method for efficiently discarding data packets destined to a mobile station connected to both a master base station and a secondary base station. The master base station configures a secondary discard function in a lower layer of the secondary base station, based on the master discard function in the higher layer of the master base station. The master base station forwards the data packet from the higher layer to the lower of the secondary base station. The secondary discard function of the lower layer at the secondary base station discards the received data packet upon expiry of the secondary timer started by the lower layer upon reception of the data packet from the higher layer at the master base station.

A network element one or more network ports, network time circuitry and packet processing circuitry. The network ports are configured to communicate with a communication network. The network time circuitry is configured to track a network time defined in the communication network. In some embodiments the packet processing circuitry is configured to receive a definition of one or more timeslots that are synchronized to the network time, and to send outbound packets to the communication network depending on the timeslots. In some embodiments the packet processing circuitry is configured to process inbound packets, which are received from the communication network, depending on the timeslots.

A communication apparatus determines whether to delete a packet yet to be transmitted that is stored in a transmission queue from the transmission queue when new data to be transmitted to another communication apparatus is generated. In a case where the packet yet to be transmitted is determined to be deleted, the communication apparatus deletes the packet yet to be transmitted that is stored in the transmission queue while maintaining the communication connection with the another communication apparatus, and transmits a packet to be transmitted corresponding to the new data to the another apparatus.
