A method for transmitting multiple data streams of different communication services over a multipath transmission system includes: providing data to be transmitted, wherein the data to be transmitted comprises first data and second data; detecting, out of a plurality of communication services, a first communication service the first data belongs to and a second communication service the second data belongs to; mapping the first data to a first data stream and the second data to a second data stream based on the first and second detected communication services; scheduling transfer of the first data stream and the second data stream based on the first classification parameter assigned to the first and second communication services; and scheduling transmission of the first data and the second data to the destination communication device based on the at least one second classification parameter assigned to the first and second communication services.

A network system that implements quality of service (QoS) by rate limiting at a logical network entity is provided. The logical network entity includes multiple transport nodes for transporting network traffic in and out of the logical network entity. The system monitors traffic loads of the multiple transport nodes of the logical network entity. The system allocates a local CR and a local BS to each of the multiple transport nodes. The allocated local CR and the local BS are determined based on the CR and BS parameters of the logical network entity and based on the monitored traffic loads. Each transport node of the logical network entity in turn controls an amount of data being processed by the transport node based on a token bucket value that is computed based on the local CR and the local BS of the transport node.

Introduced here are approaches to classifying traffic that comprises data packets. For each data packet, a classification engine implemented on a computing device can identify an appropriate class from amongst multiple classes using a lookup table implemented in a memory. The memory could be, for example, static random-access memory (SRAM) as further discussed below. Moreover, the classification engine may associate an identifier with each data packet that specifies the class into which the data packet has been assigned. For example, each data packet could have an identifier appended thereto (e.g., in the form of metadata). Then, the data packets can be placed into queues based on the identifiers. Each queue may be associated with a different identifier (and thus a different class).

A switch in a slice-based network can be used to enforce quality of service (“QoS”). Agents can run in the switches, such as in the core of each switch. The switches can sort ingress packets into slice-specific ingress queues in a slice-based pool. The slices can have different QoS prioritizations. A switch-wide policing algorithm can move the slice-specific packets to egress interfaces. Then, one or more user-defined egress policing algorithms can prioritize which packets are sent out into the network first based on slice classifications.

A system includes a first and at least one second processing circuit, a configuration engine, and a switch. The configuration engine stores a virtual link configuration for a plurality of virtual links, which indicates a priority and a predetermined network pathway for communicating data packets from the first processing circuit to the at least one second processing circuit. The configuration engine automatically assigns priority to a first virtual link of the plurality of virtual links based on at least one of latency or jitter. The switch receives a first data packet from the first processing circuit. A first virtual link identifier is extracted from the first data packet. A first priority and a first predetermined network pathway corresponding to the first virtual link identifier from the virtual link configuration are retrieved. The first data packet is transmitted along the first predetermined network pathway based on the first priority.

A wireless access point software application, adapted to be run within a wireless access point, classifies network data packets with classification identifiers provided by RTC/RTE devices without scanning the content of them. The wireless access point software application receives inbound and outbound packet classification identifiers from the RTC/RTE applications running on the RTC/RTE devices. The identifiers are provided to a hardware data packet classifier. The hardware data packet classifier applies the identifiers against ingress packets and egress packets respectively. Data packets of the same class are assigned with a same priority. The prioritized network data packets are scheduled for transmission based on their respective priorities. The scheduled network data packets are forwarded to respective network interfaces for transmission.

This application discloses a service level configuration methods and apparatuses, and belongs to the field of communications network technologies. According to an example method, a target service level used by a first forwarding node to forward a data flow is directly determined based on a transmission parameter of the data flow and service level information of the first forwarding node, and service level configuration is performed on the first forwarding node. Because a transmission parameter of the target service level of the first forwarding node and the transmission parameter of the data flow meet a first target condition, if the first target condition is a delay requirement required by a special service and the first forwarding node transmits the data flow by using the target service level, transmission of the data flow may meet the delay requirement required by the special service.

A method and an apparatus are provided for managing quality of service (QoS) in a communication network. A plurality of data flows related to at least one application associated with a user equipment (UE) is received. At least one data flow that requires QoS management related to the at least one application is identified from the plurality of data flows based on an analysis of at least one of a plurality of attributes related to the at least one application. The at least one data flow is classified into a QoS class associated with the at least one application. The at least one data flow is prioritized based on the QoS class.

A system for controlling power distribution within a vehicular communication network, including a power source equipment comprising a first port in communication with a network node module of a device, and a Power over Ethernet (POE) management module. The POE management module is configured to enable POE to the device via the first port, monitor a current draw of the device, determine whether the current draw of the device exceeds a threshold, and disable POE to the device, responsive to determining that the current draw exceeds the threshold.

A network load balancing apparatus has a data buffer for each communication path of a received packet's transfer destinations, calculates a first hash value using a field value contained in the packet, determines, based on the field value of the packet or the first hash value, a communication path of a transfer destination of the packet subject to external transfer control for transmission to a predetermined external server, determines, based on the first hash value, a communication path of a transfer destination of the packet to be subject to priority control, determines, based on a second hash value based on the first hash value, a communication path of a transfer destination of the packet to be subject to load balancing control, to match a preset load balancing situation of the data buffer, and transmits the packet to a data buffer corresponding to the communication path of the transfer destination.
