摘要： Methods and systems are provided for latency-oriented router. An incoming packet is received on a first interface. The type of the incoming packet is determined. Upon the detection that the incoming packet belongs to latency-critical traffic, the incoming packet is duplicated into one or more copies. Subsequently, the duplicated copies are sent to a second interface in a delayed fashion where the duplicated copies are spread over a time period. The duplicated copies are received and processed at the second interface.

摘要： 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.

摘要： A device includes a first message queue, a second message queue, a first queue manager coupled to the first message queue, and a second queue manager coupled to the second message queue. The first message queue is configured to store messages received from a first source. The second message queue is configured to store messages received from a second source. The first queue manager is configured to, based, at least in part, on detecting that a first message is added to the first message queue, send a request to a second queue manager The request includes an indication of the first message. The first queue manager is also configured to, based on receiving an acknowledgement from the second queue manager and determining that the acknowledgement indicates that a second message matching the first message is stored in the second message queue, output a match indicator indicating the first message.

摘要： A system includes a plurality of client terminals, and a reception service system receiving data from the plurality of client terminals. The reception service system includes a first queue configured to receive data to be a target of predetermined processing, and a second queue configured to receive data not to be a target of the predetermined processing. Each of the plurality of client terminals transmits data relating to an event that occurred in the client terminal, to the second queue based on a second transmission rule for transmission of data to the second queue in a case where it is determined that an amount of data transmitted from the client terminal to the first queue per unit time exceeds a predetermined value.

摘要： The present disclosure generally relates to a device, method, or system for time sensitive networking. In an example, the device can include a time-sensitive networking controller and a scheduler. The device also includes an enhanced gate control list maintained on the time-sensitive networking controller to include a direct memory access address, a launch time, and a pre-fetch time for a data packet. The device may also include a transmitter of the time-sensitive networking controller to transmit the data packet retrieved using the direct memory access address at the launch time identified by the scheduler.

摘要： The technologies described herein are generally directed toward shedding processing loads associated with route updates. According to an embodiment, a system can comprise a processor and a memory that can enable operations facilitating performance of operations including facilitating receiving, from a second routing device via a network, a communication. The operations can further comprise, in response to a queueing delay being determined to be less than a threshold, queueing, in the queue, the communication for a third routing device selected according to a first selection process as being on a route to a destination routing device for the communication. Further, operations to, in response to the queueing delay of the queue being determined to be equal to or above the threshold, transmit the communication to a fourth routing device, with the fourth routing device being selected according to a second selection process different than the first selection process.

摘要： A network device adds an extreme low latency (ELL) service packet to an ELL queue, and adds a (time sensitive) TS service packet to a TS queue. A packet in the TS queue is sent within a time window corresponding to the TS queue, and the packet in the TS queue is not allowed to be sent within a time period beyond the time window corresponding to the TS queue. When a remaining time period obtained by subtracting a time period required by a to-be-sent TS service packet within the time window from the time window is greater than or equal to a first threshold, a packet in the ELL queue is allowed to be sent within the time window corresponding to the TS queue. The first threshold is a time period required for sending one or more ELL service packets in the ELL queue.

摘要： This application provides a packet processing method and apparatus, to avoid chain impact of an abnormal packet caused by an abnormal underlying latency on an uncertain target flow. The method includes: receiving, by a first device, a first packet sent by a second device, where the first packet carries a first label, and the first label is determined based on a cycle in which the second device sends the first packet; determining, by the first device based on the first label, whether the first packet is a normal packet; if determining that the first packet is a normal packet, determining, by the first device, a second packet based on the first packet, where the second packet carries a second label; and sending, by the first device, the second packet to a third device in a first cycle, where the second label is determined based on the first cycle.

摘要： A system for scheduling prioritized traffic in a scrambled and coded multiple access (SCMA) system multiple terminals and a gateway. Each terminal is configured to receive packets from user devices and place the packets on various input queues. The packets are en-queued onto a plurality of output queues based on priority or service class. The terminal is further configured to detect one or more available SCMA slots within a frame of a communication system, and de-queue packets from the highest priority output queue onto the frame via one or more SCMA bursts. The terminal includes transceiver for transmitting/receiving frames of the communication system to/from the gateway. The terminals autonomously transmit SCMA bursts relative to each other.
