摘要： In embodiments, a fast Fourier transform (FFT) engine includes a series of stages, each stage containing a butterfly and a data normalization device configured to scale output of the stage's butterfly. The scaling factors are adjusted, for example, periodically or on as-needed basis, so that the dynamic range of the butterflies and the buffers is increased for a given bit-width, or the bit-width of these devices is decreased for the same dynamic range. Additionally, bit-width of other buffer(s) is decreased because of the scaling of the data.

摘要： A network device includes a memory, a routing engine and a forwarding engine. The memory stores a forwarding table and the routing engine constructs a first composite next hop that includes multiple next hops, where each of the multiple next hops represents an action to be taken on a data unit as it transits the network device or represents another composite next hop, and where the first composite next hop specifies a function to be performed on the plurality of next hops. The routing engine further stores the composite next hop in an entry of the forwarding table. The forwarding engine retrieves the composite next hop from the forwarding table, and forwards a data unit towards one or more network destinations based on the composite next hop.

摘要： An information handling system includes a wireless device and interference suppression apparatus that adapts to the different interference problems experienced by the wireless device when the system changes from one operating mode or state to another. The interference suppression apparatus includes a controller that instructs an adaptive filter with respect to the appropriate filter characteristics to employ to suppress interference when the system is operating in a first mode. When the system changes to a second mode of operation, the interference suppression apparatus updates the filter characteristics to filter characteristics which are appropriate for suppressing interference associated with the second mode of operation.

摘要： Distribution parameter mapping determines the bit error probability (BEP) of a burst transmitted from a base station to the mobile station using a modulation and coding scheme (MCS) specified in the EDGE standard. Depending on whether the multi-bit soft decisions of the burst most resemble a Gaussian or a Rician distribution, the statistical parameters μ and □ or A and □ are determined. The ratio μ/□ or A/□ is mapped to an empirically determined BEP in a Gaussian or Rician lookup table, respectively. The BEPs are not influenced by the degree of code redundancy in the MCS. The BEPs for the four bursts in a radio block are then averaged, filtered and quantized according to the EDGE standard. The quantization level of the average BEP is reported to the base station so that subsequent radio blocks can be transmitted using an MCS that is appropriate for the estimated BEP.

摘要： An egress device of a network tunnel is configured to receive fragmented packets over a tunnel interface when the network tunnel is defined using information that is not present in all of the fragmented packets. For example, an egress device includes an interface to receive packets associated with the network tunnel, at least some of the packets being fragmented packets that are fragments of tunnel encapsulated packets. Some of the fragmented packets include network layer information associated with a network layer header of an original unfragmented tunnel encapsulated packet and do not include transport layer information associated with a transport layer header of the original unfragmented tunnel encapsulated packet. A forwarding engine of the egress device uses a multi-stage chained lookup to determine whether packets conform to tunnel definitions for the network tunnel that define the network tunnel by specifying both network layer information and transport layer information required for the packets.

摘要： In general, techniques are described that facilitate application of service within MPLS networks. More specifically, a router comprises a forwarding plane, a service plane and a routing engine. The routing engine maintains data defining an association between a handle identifying a property common to a plurality of packets of a particular context and one or more MPLS labels associated with these packets. The routing engine automatically generates and installs a filter to identify these packets within both the forwarding and service planes. The forwarding plane applies the filter to incoming packets to determine whether each of the incoming packets includes a label matching any of the labels of the filter and forwards the incoming packets to the service plane upon a match. The service card selects one or more services identified by the filter and applies the selected one or more services to the incoming packet.

摘要： A configurable decoder within a receiver (for example, within a wireless communication device) includes numerous decoders. In one mode, the multiple decoders are used to decode different sub-packets of a packet. When one decoder completes decoding the last sub-packet assigned to it of the packet, then that decoder generates a packet done indication. A control circuit receives the packet done indications, and when all the decoders have generated packet done indications then the control circuit initiates an action. In one example, the action is the interrupting of a processor. The processor responds by reading status information from the control circuit, thereby resetting the interrupt. End-of-packet markers are usable to generate packet done indications and to generate EOP interrupts. Similarly, end-of-group markers are usable to generate group done indications and to generate EOG interrupts. The decoder block is configurable to process sub-packets of a packet using either one or multiple decoders.
