The systems and methods of the present disclosure are directed towards a dynamic system that is configured to identify and map networked traffic, such as that of video, voice, file transfer, and web based applications to predetermined Quality of Service (QoS) classes. The different QoS classes can be associated with different traffic priorities. The networked traffic can be encrypted, which can prevent an intermediate device from processing or otherwise reading the packet headers of the traffic. The systems and methods of the present disclosure can predict QoS classes for encrypted traffic based on traffic patterns and other characteristics of the encrypted traffic.

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.

A communication equipment receives a plurality of network sessions and includes a memory and a processor. The memory stores a plurality of software modules. The processor is connected to the memory and configured to implement the following steps. A network session inferring step is performed to execute an inference software module, and the inference software module processes at least one network packet of each of the network sessions and a packet characteristic module according to a machine learning algorithm to infer a priority level. An adaptive priority list establishing step is performed to execute a classification software module, and the classification software module establishes an adaptive priority list according to the priority levels of the network sessions. The communication equipment transmits the network packets of each of the network sessions to a network according to the adaptive priority list so as to set QoS of the network sessions.

Methods are provided to categorize and filter node metadata by adding a priority field to the node metadata, obtained as part of in-band network telemetry data collection. The methods involve obtaining, by a first network device, a packet having a header and a payload and adding, by the first network device, to the header of the packet, metadata which includes first telemetry data and a metadata priority level that indicates a priority of the first telemetry data added to the header of the packet by the first network device. The methods further involve providing the packet to a second network device in a path of a network.

A packet transfer device 100 includes a packet classification unit 120 configured to classify received packets, queues 140 for respective classifications, priorities being set to the queues, a dequeue processing unit 150 configured to extract packets from the queue under a predetermined rule based on the priorities set to the queues, and a queue priority control unit 130 configured to perform control, upon detecting that a reception amount of packets related to a communication flow temporarily or intermittently increases from a reception amount under a normal condition, such that a priority of one of the queues holding the packets related to the communication flow is temporarily raised from a priority under the normal condition, during a period while the reception amount of packets related to the communication flow temporarily or intermittently increases.

A method for operating a time-sensitive network, TSN, having a first, high-importance segment and a second, low-importance segment, includes remapping, using TSN per-port priority regeneration, priority labels attached to data streams received on the first port and the second port to updated priority labels; splitting the data streams into a “preempting” class and a “preemptable” class based on a mapping from updated priority labels to classes; and forwarding the data streams from a border network element to at least one next-hop network element. When congestion is present on a link to the next-hop network element, the forwarding of “preempting” data streams takes precedence over the forwarding of “preemptable” data streams.

A Self-Describing Packet block (SDPB) is defined that allows concurrent processing of various fixed headers in a packet block defined to take advantage of multiple cores in a networking node forwarding path architecture. SPDB allows concurrent processing of various pieces of header data, metadata, and conditional commands carried in the same data packet by checking a serialization flag set upon creation of the data packet, without needing to serialize the processing or even parsing of the packet. When one or h more commands in one or more sub-blocks may be processed concurrently, the one or more commands are distributed to multiple processing resources for processing the commands in parallel. This architecture allows multiple unique functionalities each with their own separate outcome (execution of commands, doing service chaining, performing telemetry, allows virtualization and path steering) to be performed concurrently with simplified packet architecture without incurring additional encapsulation overhead.

The present disclosure relates to the field of wireless communication, and discloses a data transmission method and apparatus, a terminal device, and a storage medium. The method is applied in a terminal device including a Medium Access Control (MAC) layer and a physical layer. The method includes: delivering, by the physical layer, indication information to the MAC layer; adjusting, by the MAC layer based on the indication information, a priority of data at the MAC layer from prioritized to de-prioritized; and re-transmitting the data; or adjusting, by the MAC layer based on the indication information, a priority of a Scheduling Request (SR) at the MAC layer from prioritized to de-prioritized; and re-transmitting the SR.

A computer software application running on a wireless communication device determines whether an application scenario is urgent or nonurgent, and determines whether the user state is interest, uninterested or absent. The application sends the application scenario and the user state to a wireless networking device. The wireless networking device determines the user roles of different wireless communication devices. It further adjusts priorities of data packets destined to the wireless communication device based on the application scenario, the user state and the user role when downlink to the wireless communication device is congested. The priority is decreased when the application scenario is unurgent, the user role is a listener, and the user state is uninterested or absent.

A method of communicating a packet between a first node and a second node, the packet comprising a data payload and a portion of information preceding the data payload. The method comprises: (i) first, identifying a quality of a channel between the first node and the second node; (ii) second, in response to the quality of the channel, selecting a manner of communication of the information preceding the data payload; (iii) third, encoding the selected manner of communication in the portion of information preceding data payload; and (iv) fourth, transmitting the packet from the first node to the second node.
