A method and an electronic device for managing network resources among application traffic are provided. The method comprises identifying a real time application that is running on the electronic device and consuming network resources, determining whether the real time application belongs to a prioritized class, based on the real time application belonging to the prioritized class, determining a User Identifier (UID) of the real time application, and prioritizing the network resources for the real time application based on the UID.

A system for optimizing network traffic is described. The system includes a transport communication protocol (TCP) controller configured to acquire data regarding a flow of a plurality of data packets over a link and to determine TCP characteristics for the flow, a traffic prioritization module configured to assign a flow priority to the flow, and a traffic priority controller configured detect congestion on the link and determine a congestion window size for the flow based on the flow priority and the TCP characteristics.

A data transmission method and an apparatus. A transmission priority of a data packet may be changed so that the data packet has an opportunity to continue to be transmitted. when the data packet just arrives at a PDCP layer of a communication apparatus, and the priority of the data packet is an initial priority. If the data packet is not sent or is not successfully sent after a decoding moment of a receiver is exceeded, compared with a manner of directly discarding the data packet, in this manner, the priority of the data packet may be changed, so that the data packet has the opportunity to continue to be transmitted. This helps improve a compression rate and a decoding effect, to improve user experience.

A quality of service adjusting method based on application categories is configured to adjust a Quality of Service (QoS) of a communication device. A network session processing step is performed to drive a hardware accelerator to process a plurality of network sessions. A packet receiving step is performed to drive a processing unit to receive a first packet group of each of the network sessions. A packet analyzing step is performed to execute a packet inspecting module to analyze a plurality of packet data of the first packet group of each of the network sessions, and to classify an application corresponding to each of the network sessions. A list establishing step is performed to establish a priority list. A bandwidth distributing step is performed to distribute a network bandwidth to a second packet group of each of the network sessions according to the priority list.

A communication method includes that a first network device generates indication information based on service usage of a first network slice and a service usage threshold of the first network slice, and sends the indication information to a second network device. The second network device controls resource pre-emption based on the indication information.

The present technology discloses systems, methods, and computer-readable media to establish at least one target for a network, the target including at least one of an ingress parameter or an egress parameter and a policy for network packets; receive at least one network packet on the network; search for at least one matching target from the at least one targets, the at least matching target comprising parameters that match the at least one network packet; apply a policy in the at least one matching target to the at least one network packet; and forward the at least one network packet in accordance with the policy.

A network element includes at least one headroom buffer, and flow-control circuitry. The headroom buffer is configured for receiving and storing packets from a peer network element having at least two data sources, each headroom buffer serving multiple packets. The flow-control circuitry is configured to quantify a congestion severity measure, and, in response to detecting a congestion in the headroom buffer, to send to the peer network element pause-request signaling that instructs the peer network element to stop transmitting packets that (i) are associated with the congested headroom buffer and (ii) have priorities that are selected based on the congestion severity measure.

A packet forwarding method to shorten a transmission latency of an elephant flow is provided. In the method, for a first packet flow used as an elephant flow, a network device may receive a plurality of packets of the first packet flow, and determine a characteristic parameter of the first packet flow based on the plurality of packets, where the characteristic parameter of the first packet flow is used to indicate a transmission latency of the first packet flow. After determining the characteristic parameter of the first packet flow, the network device determines a forwarding policy of the first packet flow based on the characteristic parameter of the first packet flow. The forwarding policy of the first packet flow is used to indicate latency sensitivity of the first packet flow.

This application discloses a network and a data transmission method and apparatus, and belongs to the field of communication technologies. The network includes a core device and an edge device. The edge device identifies a service type of a first service packet from the core device, and reports a service type identifier of the first packet to the core device. The core device determines a priority corresponding to the service type identifier based on a stored service priority correspondence, and forwards, based on the priority, a service packet belonging to a same service flow as the first service packet. A strong service identification capability of the edge device is used to precisely identify thousands of service types, and a strong entry storage capability of the core device is used to store a correspondence that records thousands of service types and priorities. This effectively avoids problems such as transmission congestion and a packet loss that are caused by an incapability of precisely identifying a service type and allocation of a same priority to service packets of different service types.

A controller is provided for use with a CD, a WAN, and a service provider server, the HNC includes: a memory; and a processor configured to execute instructions stored on memory to cause the HNC to: establish a priority time period; associate the priority time period with a first application; establish a first service flow queue having a first QoS during priority period; establish a second service flow queue having a second QoS; receive first upstream packets and second upstream packets; assign the first upstream packets to a first upstream queue during the priority time period; assign the second upstream packets to a second upstream queue; receive first downstream packets and second downstream packets; assign the first downstream packets to a first downstream queue during the priority time period; and assign the second downstream packets to a second downstream queue.
