Predictive management of a network buffer is contemplated. The network buffer maybe predictively managed to control packet drop based at least in part on predicted sojourn time. The predicted sojourn time may be determined to predict time needed from an arriving packet to travel through a queue of the network buffer.

Predictive management of a network buffer

A method for automatic redundant connections includes (1) receiving a first notification message indicating a problem with a primary wide area network (WAN) communication link serving a local area network and (2) in response to receiving the first notification message, establishing a first backup WAN communication link to serve the LAN, using a WAN communication link of a first user equipment device connected to the LAN. The WAN communication link of the first user equipment device is, for example, a wireless communication link.

A profile optimizing method is provided for a downstream channel transmission of active subcarriers to user devices. The method includes steps of receiving channel measurement data from each user device for each subcarrier, calculating a maximum bit-loading value for each user device per subcarrier, grouping the user devices into a plurality of clusters based on a proximity of the maximum bit-loading values of a first user device to those of a second user device within the particular cluster, assigning each user device within the particular cluster to a single cluster profile. A plurality of single cluster profiles for the plurality of clusters forms a set of cluster profiles. The method further includes steps of determining a channel capacity ratio for the set of cluster profiles, and combining at least two single profiles of the set of cluster profiles into a coalesced profile pair.

A method of reducing transmission power for an encoded data stream includes the steps of receiving an incoming data stream having equal probability for a plurality of incoming data bits, assigning a symbol scheme to the received data bits of the incoming data stream according to probabilities of occurrence of individual ones of the received data bits, and transmitting an outgoing data stream according to the assigned symbol scheme having a second average transmit power, different than the first average transmit power, for a plurality of outgoing symbols.

Signal power reduction systems and methods

A method for wireless communication network control includes (1) receiving, at an information technology (IT) device, a first steering policy from an application manager remote from the IT device, the first steering policy specifying a first allocation of data among a plurality of wireless communication links available to the IT device; and (2) sending uplink or downlink data from a first application client on the IT device to a mobility manager remote from the IT device over at least one of the plurality of wireless communication links available to the IT device, according to the first allocation of data.

Media streaming is contemplated, such as but not necessarily limited to facilitating streaming of audio, video, etc. over networks operating according to Information Center Networking (ICN) principles. The media streaming may be facilitated with a request-response protocol of ICN being leveraged to enable streaming media at infinite scalability without a priori knowledge or guarantee of network resources and bandwidth.

A method for interfacing one or more information technology (IT) devices with an application server includes (1) receiving, at a control system, first downlink data from the application server, and (2) steering the first downlink data from the control system to a first IT device via at least one of a first plurality of parallel data communication links between the first IT device and the control system, according to a first steering policy.

A method for interfacing an information technology device with a gateway includes (1) receiving, at the gateway, first downlink data, and (2) steering the first downlink data from the gateway to a first information technology (IT) device via at least one of a first plurality of parallel data communication links between the first IT device and the gateway, according to a first steering policy.

Methods, systems, and devices for Content-Centric Networking (CCN) are described. In some cases, a node may receive a CCN packet from an upstream node and communicate the CCN packet to one or more downstream nodes (e.g., that previously requested the CCN packet). In a first case, the node may establish a persistent internet protocol (IP) tunnel with the downstream node and communicate the CCN packet to the downstream node by the persistent IP tunnel. Here, a cable modem between the node and the downstream node may not decode the CCN packet. In a second case, the node may append an identifier to the CCN packet prior to communicating the CCN packet to the one or more downstream nodes. Here, the identifier may indicate to the downstream nodes which CCN packets are relevant to the downstream node.

A receiver is configured to capture a plurality of linearly distorted OFDM symbols transmitted over a signal path. The receiver forms the captured OFDM symbols into an overlapped compound data block that includes payload data and at least one pseudo-extension, processes the overlapped compound block with circular convolution in the time domain using an inverse channel response, or frequency domain equalization, to produce an equalized compound block, and discards end portions of the equalized block to produce a narrow equalized block. The end portion corresponds with the pseudo-extension, and the narrow block corresponds with the payload data. The receiver cascades multiple narrow equalized blocks to form a de-ghosted signal stream of OFDM symbols. The OFDM symbols may be OFDM or OFDMA, and may or may not include a cyclic prefix, which will have a different length from the pseudo-extension.
