Metrics may be used by user equipment (UE) to steer traffic through different access networks or to provide access network mobility decisions. For example, in one implementation, a UE may determine metrics relating to network conditions associated with at least a non-cellular access network. The metrics may include receive a first value relating to channel utilization of a link between the UE and a WLAN; and a second value relating to a data rate of a link between the WLAN and a WAN.

The disclosed technology addresses the need in the art for a solution configured to prevent network retransmission timeouts. A system is configured to receive a data packet originating from a sender and forward the data packet to a receiver. The system receives, from the receiver, an acknowledgment message that corresponds to the data packet and holds the acknowledgment message in a buffer until a delay time period expires, wherein the delay time period is determined based on a log of acknowledgment times. When the delay time period expires, the system forwards the acknowledgement to the sender.

The present invention provides according to one of its aspects a method of queueing a data frame in one of a plurality of traffic queues at a communication station for transmission over a communication channel in a communication network comprising a plurality stations and an access point (AP). The method comprising selecting a traffic queue based on at least one of 1) a transmission mode, direct link or uplink, of the data frame, and 2) a transmission mode of the traffic queue; and queueing the data frame in the selected traffic queue. The transmission mode of the traffic queue may be a Multi-User (MU) uplink (UL) mode if a data frame previously stored in the traffic queue has been transmitted, since a predetermined period of time, in a resource unit (RU) provided by the AP within a transmission opportunity granted to the AP on the communication channel. The transmission mode may also be a Single-User (SU) mode.

A method of reducing the bandwidth usage of a network comprises intercepting traffic between a TCP server and a TCP client using TCP protocols that use client acknowledgements; identifying client acknowledgements from the TCP protocols; identifying the sequence number of a last received client acknowledgements from the intercepted traffic; identifying the sequence number of a last sent client acknowledgement from the intercepted traffic; calculating an unacknowledged byte value based on the difference between the last received client acknowledgement sequence number and the last sent client acknowledgement sequence number; comparing the calculated unacknowledged byte value with a predetermined threshold value, to determine whether the calculated unacknowledged byte value is at least as great as the predetermined threshold value; and transmitting the identified client acknowledgements into the network when the compared unacknowledged byte value is at least as great as the predetermined threshold value.

The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for indicating a priority in a D2D communication system, the method comprising: receiving a SDU with a priority corresponding to the SDU from an upper layer; generating a PDU including the SDU and the corresponding priority; and transmitting the PDU to a peer device.

The present application discloses a flow forwarding method, device, and system. The method includes: receiving, by an edge node, an intelligent routing service request packet, and the packet includes a constraint condition required for establishing the intelligent routing service; if the edge node does not find, in a flow table, a corresponding matching flow table entry of characteristic information, sending, by the edge node, a first message to a controller, where the first message includes identification information of the edge node and the characteristic information and the edge node is an ingress edge-node or an egress edge-node that receives the packet; receiving, a first flow table entry sent by the controller, where the first flow table entry is generated according to the first message and meets the constraint condition; and processing, according to the first flow table entry, a packet sent by the user side device.

A system and a method for receiving data packets at the inputs of two data handlers. Each data handler compares address data in the individual data packet with a first and a second list of addresses and forward packets to each other, so that data packets with one of the first addresses are fed to one data handler and packets with one of the second addresses are fed to the other data handler. The data handlers output the data packets received so that one data handler outputs all packets with addresses of the first addresses and the other data handler outputs all packets with addresses of the second addresses.

It is presented a method performed in a first network node. The method comprises the steps of: receiving an uplink transmission from a mobile communication terminal; determining, based on content of the uplink transmission, information to be transmitted over a first communication channel when the content comprises control data intended for a second network node; transmitting the information over the first communication channel to the second network node when the information is to be transmitted over the first communication channel; and transmitting the information via a second communication channel, the second communication channel being physically separate from the first communication channel, when the information is not to be transmitted over the first communication channel. A corresponding network node is also presented.

A data transmission method and a device, where the method includes obtaining a service data packet that needs to be sent to a peer device, determining a priority corresponding to the service data packet, writing the service data packet to a packet buffer when the priority is lower than a preset level, encapsulating the data stored in the packet buffer in order to generate a to-be-sent packet when data stored in the packet buffer meets a transmission condition, and sending the to-be-sent packet to the peer device.

Techniques are disclosed relating to a split communications fabric topology. In some embodiments, an apparatus includes a communications fabric structure with multiple fabric units. The fabric units may be configured to arbitrate among control packets of different messages. In some embodiments, a processing element is configured to generate a message that includes a control packet and one or more data packets. In some embodiments, the processing element is configured to transmit the control packet to a destination processing element (e.g., a memory controller) via the communications fabric structure and transmit the data packets to a data buffer. In some embodiments, the destination processing element is configured to retrieve the data packets from the data buffer in response to receiving the control packet via the hierarchical fabric structure. In these embodiments, bypassing the fabric structure for data packets may reduce power consumption.
