This application provides a congestion information collection method and a related device. The method includes: A first connection node receives a first packet, obtains congestion information of a segment link including the first connection node, and records the congestion information in a parameter field corresponding to the first connection node in the first packet. By encapsulating a plurality of parameter fields that can be used to record congestion information into a packet, a node on a forwarding path can record congestion information of a plurality of segment links of a transmission path of the packet. In this way, a source node can plan a transmission path of a new packet based on congestion information of each segment link, or a node that generates a packet reduces a packet sending rate when the sent packet needs to pass through a congested node.

The proposed technology relates to methods and radio network nodes for Explicit Congestion Notification, ECN, marking of user traffic in wireless communication networks. For example, a method performed by a sending radio network node (10) comprises the step of monitoring (S10) a congestion metric on a data radio bearer, and the step of transmitting (S20) control information indicating traffic congestion on the same data radio bearer, based on the monitored congestion metric, to a receiving radio network node (20).Further, a method performed by a receiving radio network node (20) comprises the step of receiving (S100) control information indicating traffic congestion on a data radio bearer, based on a congestion metric, from a sending radio network node (10), and the step of marking (S200) next ECN-capable user packet of the user traffic on the same data radio bearer with ECN marking, based on the received control information.

Systems are presented for processing packets in a network switch. One network device includes a processor, an Ethernet switch, a PCIe switch, and a packet processor. The processor is for executing a controller program, and the Ethernet switch is for switching packets among a ports. Further, the PCIe switch is coupled to the processor and the Ethernet switch, and the packet processor, coupled to the Ethernet switch and the PCIe switch, is operable to modify an application header of an incoming packet and send the incoming packet to one of the ports. The controller program is operable to configure the Ethernet switch and the packet processor to define processing of packets. The controller program is operable to send a first configuration rule to the Ethernet switch, the first configuration rule defining that packets of a network flow requiring header modification be forwarded to the packet processor.

A method and apparatus are provided for reporting a buffer status to a Node B, by a User Equipment (UE), in a mobile communication system. The method includes checking if a resource for data to be transmitted to the Node B is available, when there is a buffer status report triggered to be transmitted to the Node B; transmitting the buffer status report by using the available resource, if the resource is available; and transmitting a scheduling request to the Node B, if the resource has not been allocated for a predetermined time after the buffer status report is triggered.

A method and apparatus for performing capture caching in a wireless network. A wireless transmit/receive unit (WTRU) or client device captures data from neighboring devices in the network and internally cache data that was traditionally cached in an edge node. The WTRU reassembles the captured data packets on a condition that the WTRU requests content associated with the captured data packets. If any segments are missing from the captured data packets, only those missing segments are retrieved from the server to repair the data. The reassembly of the data and the repair of missing segments is deferred until the data is needed by the WTRU.

In a communication system having multiple nodes communicably connected via a ring network, at least two of the nodes each includes: a packet distributor that receives an ordinary packet and an interrupt packet from another node and distributes the received packets; and an output switching unit that outputs the ordinary packet and the interrupt packet that are not addressed to the own node such that the interrupt packet is output more preferentially than the ordinary packet. When the output switching unit receives the interrupt packet while outputting the ordinary packet, the output switching unit outputs the interrupt packet by embedding it into the ordinary packet that is being output at a position between the header and trailer of the ordinary packet. When the ordinary packet transmitted from the other node contains an interrupt packet embedded therein, the packet distributor extracts the interrupt packet and distributes the extracted interrupt packet.

A method for controlling a low-power state of a pair of serial interfaces using a pair of flow-control signal lines may include enabling a first of the flow-control lines by a first one of the interfaces for signaling a transmission request to the second interface. The method may also include, in response to the transmission request, waking up to a live state from a low-power state and enabling a second flow-control line for signaling a transmission authorization to the first interface. In response to the transmission authorization, the method may include initiating a transmission of a message to the second interface, and upon reaching an offset before the end of the message transmission, disabling the first flow-control line by the first interface. The method may also include, at the end of the message transmission, disabling the second flow-control line and going back into the low-power state.

A first network device including a physical layer device. The physical layer device is configured to receive data for transmission to a second network device and receive sideband data for transmission to the second network device. The sideband data corresponds to control information, management information, and/or status information. The physical layer device is further configured to provide, via a first wired connection, the data for transmission to the second network device, generate alignment markers, insert the sideband data into the alignment markers, and selectively provide, via the same first wired connection, the alignment markers including the sideband data inserted by the physical layer device.

Embodiments of the present disclosure provide a service processing apparatus and method, and relate to the field of network service processing, and the method includes receiving, by a forwarding plane device, a packet of a first service flow, determining, by the forwarding plane device, a value-added service instance corresponding to the first service flow, and sending, by the forwarding plane device, the packet of the first service flow to the value-added service instance. In this way, a problem is resolved that a load balancer is heavily loaded because all service flow packets need to be processed using the load balancer, and generally, the load balancer may only need to allocate a value-added service instance to the first service flow packet in a service flow, thereby relieving processing pressure of the load balancer.

A bulk material tender includes a mobile frame, a hopper, and a discharge system. The mobile frame has a left side and a right side. The hopper is disposed on the mobile frame. The discharge system is configured to discharge particulate matter from the hopper. The discharge system includes a discharge auger, a deploying actuator, and a positioning actuator. The discharge auger presents a proximal end and a distal end. The deploying actuator is configured to selectively emplace the discharge auger in a stowed orientation and a deployed orientation, wherein the distal end is adjacent to the hopper in the stowed orientation. The positioning actuator configured to selectively emplace the discharge auger along the left side and the right side of the mobile frame. Once emplaced, the discharge auger discharges particulate material from the hopper toward a target location.
