  • Patent number: 9083634
    Abstract: A method for supporting congestion management in a congestion exposure-enabled network, wherein sending hosts and receiving hosts communicate with each other by sending flows of packets over network paths via intermediate routers, which, upon detecting congestion, mark packets of the flows as congestion packets by including congestion information, wherein congestion is indicated to the sending hosts via a congestion feedback mechanism, and wherein the sending hosts, upon receiving congestion indications, declare a subset of the packets they send as congestion response packets by including congestion information, depending on whether the amount of congestion response packets is balanced with the indicated congestion level or not is characterized in that aggregated congestion is determined on the basis of congestion information included in packets that are sent over the network paths between the sending hosts and the receiving hosts.

  • Patent number: 9078275
    Abstract: Methods for preventing coexistence interference between a Bluetooth Low Energy (BLE) radio and a collocated LTE radio are provided. In a first solution, the BLE radio adds padding bytes to BLE packets such that the total packet length falls in a specific range to prevent coexistence interference. In a second solution, the BLE radio limits the total BLE packet length to a predefined length to prevent coexistence interference. In a third solution, the data rate for transmitting the BLE packets is higher than a predefined rate to prevent coexistence interference. In a fourth solution, the BLE radio dynamically adjusts the time inter-frame-spacing (T_IFS) value to prevent coexistence interference with the collocated LTE radio.

  • Patent number: 9014196
    Abstract: Messages from a physical layer of each communication band and communication channel associated with each protocol utilized in a multi-band, multi-protocol network may be aggregated into a single multi-protocol layer called, for example, a super channel layer. An optimal communication path may be identified from among the communication bands and/or communication channels based on information borne by the single multi-protocol layer. A communication session may be established via optimal communication path. The communication path may include different channels within a single communication bands, and/or channels selected from different communication bands. In this regard, channels from the same or different communication bands may be combined to provide an optimal communication path. The single multi-protocol layer may be characterized as a sublayer located within the data link layer. Accordingly, the single multi-protocol layer may be located above a MAC layer, both of which are part of the data link layer.
