    摘要： A method and apparatus for locating a Wi-Fi hotspot for offloading wireless traffic from a cellular network are disclosed. For example, the method obtains network traffic data for the second type of wireless access network for a geographical area, and obtains a list of sectors in the geographical area. The method selects at least one sector from the list of sectors to be relieved, and determines a geographical range for the at least one sector. The method then obtains at least one hotspot of the first type of wireless access network within the geographical range, wherein the at least one hotspot is a potential location for offloading the wireless traffic from the second type of wireless access network.

    摘要： A switching fabric connects input ports to output ports. Each input has an input pointer referencing an output port, and each output has an output pointer referencing an input port. An arbiter includes input and output credit allocators, and an arbitration module (matcher). The input credit allocator resets input credits associated with input/output pairs and updates the input pointers. Similarly, the output credit allocator resets output credits associated with input/output pairs and updates the output pointers. The matcher matches inputs to outputs based on pending requests and available input and output credits. A scheduler schedules transmissions through the cross-bar switch according to the arbiter's matches.

    摘要： Data cells of plural classes are transferred from input ports to output ports through a switch by storing the cells at each input port in class-specific virtual output queues (VOQ) within sets of VOQs associated with output ports, and providing credits to VOQs according to class-associated guaranteed bandwidths. When a cell is received at a VOQ having credits, a high-priority request for transfer is generated. If a cell is received at a VOQ that does not have any available credits, a low-priority request for transfer is generated. In response to requests, grants are issued to VOQ sets without regard to class, high-priority requests being favored over low-priority requests. When a grant is received for a particular VOQ set, an arbitrator selects a VOQ from the set, giving priority to VOQs having credits over VOQs without credits, and a cell from the selected VOQ is transferred. Requests generated from all input ports are forwarded to a central scheduler associated with a switch fabric slice, the central scheduler issuing the grants. The switch fabric may comprise multiple slices and a central scheduler, across which requests may be distributed in parallel, for example, the switch fabric slices being selected in a fixed order. While all high-priority requests are granted, low priority requests may be granted by the central scheduler according to a weighted fair share policy.

    摘要： A method and apparatus for forecasting busy hour traffic for a network are disclosed. For example, the method obtains actual traffic data for a seed time frame for each of one or more sectors in a given market and marketing projections for one or more forecast time frames for the given market, and determines a market traffic actual measure for the given market from the actual traffic data. The method obtains market traffic estimates from one or more previous runs, and updates the one or more market traffic estimates for the one or more forecast time frames beyond the seed time frame to obtain one or more updated market traffic estimates, wherein the updated market traffic estimates are used for forecasting the busy hour traffic data for each of the one or more forecast time frames beyond the seed time frame.
