    摘要: A HCPS (hierarchically clustered P2P streaming system) comprising peers grouped into clusters and hierarchies. The HCPS actively balances the uploading capabilities among clusters and executes an optimal scheduling algorithm within each cluster to ensure that system resources are optimally utilized. The HCPS comprises an architecture which can be used in practical applications, yet can achieve the streaming rate close to the theoretical upper bound.

    摘要: A capability is provided for improving service availability experienced by a user requesting access to a service via a user device, where the service has multiple service instances available from multiple data centers. A set of servicing data centers is selected for the user device. The set of servicing data centers is selected from a set of candidate data centers. The set of servicing data centers is selected from the set of candidate data centers in a manner for maximizing the independence/orthogonality of the network paths between the user device and the servicing data centers. The set of servicing data centers includes two or more of the candidate data centers from which the user device may access the service, thereby providing the user device with a primary service instance and one or more backup service instances which may be used to access the service.

    摘要: A capability for scale-up of a control plane of a Software Defined Network (SDN) using a virtual switch based overlay is presented. A central controller (CC) of the SDN that is providing control functions for a physical switch (pSwitch) of the SDN, based on a determination that the control plane between the CC and the pSwitch is congested, modifies the default flow forwarding rule on the pSwitch from a rule indicating that new traffic flows are to be forwarded to the central controller to a rule indicating that new traffic flows are to be forwarded to a virtual switch (vSwitch). Upon receipt of a first packet of a new traffic flow at the pSwitch, the pSwitch provides the first packet of the new traffic flow to the vSwitch, which in turn provides an indication of the first packet of the new traffic flow to the CC for processing by the CC.

    摘要: Methods suitable for producing textured surfaces in surfaces of objects, by which the methods are able to achieve a desired three-dimensional surface topography and optionally a desired subsurface microstructure through the use of a controlled modulation machining technique. The methods include selecting a predetermined surface texture for a surface of a body, and then imposing a superimposed sinusoidal feed-modulation on a cutting tool so as to move the cutting tool in a feed direction relative to the body while machining the body with the cutting tool and generating a machined surface of the body. The surface texture of the machined surface is intentionally controlled by at least the modulation amplitude and the modulation frequency of the superimposed sinusoidal feed-modulation.

    摘要: The present invention discloses an FDD (Frequency Division Duplex) system based multi-user beamforming method and device. The method comprises the steps of: when two or more user terminals are at respective AOAs (Angles of Arrival), determining a transmit weight of a downlink signal of each user terminal by using a null-widening algorithm, and storing the transmit weight in a network side; and, the network side grouping the user terminals based on AOA information reported by the user terminals, selecting a corresponding transmit weight for the downlink signal of each user terminal in each group based on the AOA information of the user terminals in the group, and transmitting the selected transmit weight after multiplying it by a downlink data stream of the user terminal corresponding to the transmit weight. The present invention can reduce the computation burden of the network side, enhance the efficiency of beamforming, and thus increase the capacity of the FDD system while ensuring the communication quality.
