    Abstract: The technologies disclosed herein provide improvements to the Low Extra Delay Background Transport (LEDBAT) protocol. Some aspects of the present disclosure introduce an adaptive congestion window gain for background connections. In some configurations, a gain value for influencing the transmission rate of a background connection is dynamically adjusted based on data indicating a round trip time (RTT). The RTT includes a sum of a time in which the data is communicated to a remote device and a time in which acknowledgement is data returned from the remote device. In some configurations, the gain is decreased when the RTT is below a threshold and the gain is increased when the RTT is above the threshold. Among other features, the present disclosure also provides techniques involving a modified slow-start, multiplicative decrease and periodic slowdowns. The features disclosed herein mitigate some existing issues, such as latency drift, inter-LEDBAT fairness, and unnecessary slowdowns.

    Abstract: A computing environment containing a mesh network that is adapted to provide a reliable transport mechanism over which services may be delivered. Nodes of the mesh can automatically select routable addresses without conflicts, which allows nodes of the mesh to be accessed, even as the mesh changes through the addition or deletion of nodes. Also, nodes communicate with a protocol that supports service advertisements. These advertisements can identify mesh nodes that supply services, such as file or print servers, for which devices that have not yet connected to the network may be searching. Advertisements can also identify services to be used by nodes in the network, allowing, for example, anode to select a gateway providing a reliable connection to an external network. The mesh network can be used as a transport for communication using protocols, such as TCP/IP, that generally exhibit poor performance when using unreliable transports.

    Abstract: Methods and apparatuses for Orthogonal Frequency-Division Multiplexing (OFDM) communication of non-OFDM radio signals are disclosed. The non-OFDM radio signals are force-modulated into OFDM signals. In one example, a non-OFDM signal is received and is processed into an OFDM signal to produce a created OFDM signal. An actual OFDM signal is also received and is processed together with the created OFDM signal.

    Abstract: A communication system in which an access point and one or more devices communicating through the access point adaptively apply Orthogonal Frequency Division Multiple Access (OFDMA). The access point may assign orthogonal subcarriers to devices as in conventional OFDMA, but the access point senses activity on the subcarriers and selects subcarriers without activity for assignment. In an alternative approach, a device that is configured for OFDMA communication may receive a channel assignment from a device that does not support OFDMA. The OFDMA-capable device may use only a portion of the subcarriers in the assigned channel, which may be communicated to the non-OFDMA device. During the non-OFDMA device may then ignore unused subcarriers in error detection and correction to avoid incorrectly classifying communications as erroneous. Information about OFDMA capabilities, subcarrier assignments and subcarriers in use may be communicated as information elements in network control communications, such as beacons and probe messages.
