摘要： A method and apparatus for configuring data plane behavior on network forwarding elements are described. In one embodiment, the method includes receiving, within a network element control plane, protocol configuration information extracted from a protocol application utilizing a network protocol application programming interface (API). Once the protocol configuration information is received, the protocol configuration information is processed using a control interface corresponding to the network protocol implemented by the protocol application. Once the protocol configuration information is processed, the control interface programs one or more data plane forwarding elements of the network element according to protocol configuration information. Accordingly, by providing similar control interfaces for multiple, network protocols, inter-operability between components from multiple vendors is enabled.

摘要： Methods and systems to permit multiple virtual machines (VMs) to separately configure and access a physical resource, substantially outside of a virtual machine monitor (VMM) that hosts the VMs. Each of a plurality of virtual machines (VMs) may access and configure the physical device through corresponding instances of a device driver that exposes controllable functions of the physical device within the VMs. VM-specific configuration parameters and connection information may be maintained for each of the VMs, outside of a VMM, to reconfigure or virtualize the physical device for each of the VMs with the corresponding VM-specific configuration parameters and connection information. Physical device virtualization augmentation features may be implemented within a combination of a physical device controller and a host device driver that executes outside of the VM.

摘要： A collocated radio coexistence method is disclosed. The method operates in the frequency domain to protect WiMAX downlink traffic from narrow band interference (e.g. harmonics) caused by other collocated radios, such as GSM 800 MHz, operating simultaneously with an 802.16-capable (WiMAX) radio in a multiple radio coexistence platform (MRP).

摘要： Methods and arrangements for link rate adaptation in multi-radio co-existence platforms (MRPs) are contemplated. Embodiments include transformations, code, state machines or other logic to determine an overlap between receiving by a wireless device of the MRP and transmitting by other of the wireless devices of the MRP and to select a link rate of the wireless device of the MRP based upon the determining an overlap. The embodiments may also include communicating the determined link rate to a wireless device transmitting to the wireless device of the MRP. Embodiments may also include selecting a previously used link rate if the receiving overlaps the transmitting. Embodiments may also include basing the link rate upon an overlapping or non-overlapping Signal-to-Interference-Plus-Noise-Ratio depending on the relative amounts of overlapping and non-overlapping.

摘要： An electronic device may include wireless communications circuitry that communicates in multiple radio-frequency communications bands such as cellular or local area network bands. The radio-frequency communications bands may be divided into channels that are each associated with a frequency range within a corresponding radio-frequency communications band. The electronic device may identify whether frequency harmonics associated with communications in a first radio-frequency communications band interfere with communications in a second radio-frequency communications band. The electronic device may identify channels in the second radio-frequency communications band that are affected by the frequency harmonics of the communications in the first radio-frequency communications band and configure the wireless communications circuitry to avoid communicating in the identified channels.

摘要： Embodiments of a multi-radio platform and method for mitigating the effects of interference are generally described herein. In some embodiments, the multi-radio platform includes co-located radios including a Bluetooth transceiver and a wireless network transceiver. The wireless network transceiver may apply a transmit-active noise-cancellation matrix to signals received by the wireless network transceiver when the Bluetooth transceiver is transmitting and may apply a transmit-inactive noise-cancellation matrix to signals received when the Bluetooth transceiver is not transmitting. The transmit-active noise-cancellation matrix may mitigate effects of emissions generated by the Bluetooth transceiver when the Bluetooth transceiver is transmitting. The transmit-inactive noise-cancellation matrix is to mitigate effects of platform noise generated by platform elements of the multi-radio platform.
