This document describes methods, devices, systems, and means for a switching scheme for opting in and out of multi-user orthogonal frequency-division multiple access (MU-OFDMA). In one aspect, an electronic device enters the MU-OFDMA mode to communicate via a wireless network over a shared-channel bandwidth. During the MU-OFDMA mode, the electronic device determines that an uplink-queue size is greater than a first threshold size. Responsive to the determining, the electronic device opts out of the MU-OFDMA mode and enters a single-user mode to contend for a transmit channel for transmitting uplink data.

The disclosure provides a network path determination module, a method of determining a network path, and a non-transitory storage medium which stores computer readable instruction to execute functions related to the method of determining a network path. In an aspect, the network path determination module includes not limited to: a first port; a non-transitory storage medium; and a processor coupled to the non-transitory storage medium, configured at least to: receive, through the first port, a requested generated by a detected data flow to create a forwarding entry in a network node for the data flow; retrieve a current network topology and a network status; select a network path based on the current network topology and the network status; generate a network control instruction based on the network path which has been selected; and execute the network control instruction to forward the data flow on the network path.

This disclosure relates to a method and a device for implementing hierarchical modulation of data streams. According to one of the exemplary embodiments, disclosure is directed to a method for hierarchical modulation of two data streams transmitted from a user device in a communication network. The method would include not limited to: sending, via a transceiver in the user device, a request for uplink bandwidth to an access node in the communication network; receiving, via the transceiver, an uplink bandwidth allocation provided in a downlink channel from the access node; multiplexing, at the user device, a base layer data stream and an enhanced layer data stream into a single multiplexed data stream; and transmitting, via the transceiver, the single multiplexed data stream to the access node in the uplink bandwidth allocation.

Systems and methods can use client-side video buffer occupancy for enhanced quality of experience in a communication network. The systems and methods provided herein can drive changes in the communication system using control responses. Example control responses include responses for scheduling of packets under capacity constrained conditions. An access node, such as a base station, may transmit video from a server to a client in a user device. The access node can estimate client-side video buffer occupancy and predict video playback stalls. The client-side video buffer occupancy can be estimated by emulating behavior of the client. The buffer occupancy can be used to enhance quality of experience for the user. For example, when the buffer occupancy is low, the access node may increase scheduling priority of packets conveying the video.

Pipelines for distributing file block in distributed file system network can be determined using a crawler algorithm. The crawler algorithm can iteratively identify links in a pipeline from for a starting node to one or more data storage nodes. In each iteration the pipeline can be extended based on the costs associated with the links on the pipeline with the resulting cost propagated as the pipeline is extended. The link costs indicate congestion on the links. Costs may also be back propagate from the data storage nodes.

Hierarchical modulation is performed by an access node in a communication network, by identifying, by the access node, a plurality of user devices in the communication network for hierarchical modulation reception, and sending, via a transceiver in the access node, control information to each of the identified user devices, the control information comprising an identification of a shared radio resource for use by two of the identified user devices in support of hierarchical modulation reception.
