摘要： In general, techniques are described in which packet replicators of a network device cooperate to generate a distributed hierarchical forwarding structure that the packet replicators then use to replicate and forward multicast packets to multiple output interfaces. For example, packet forwarding engines (PFEs) of a router each receive a new list of interfaces for a multicast packet stream. The PFEs individually construct a hierarchical forwarding structure based on the interface list. The hierarchical forwarding structure specifies interrelationships among the PFEs, which occupy nodes within the hierarchy. Each child PFE determines from the hierarchical forwarding structure the identity of a parent PFE and issues a token, constituting forwarding state for the distributed hierarchical forwarding structure, to the parent PFE. The parent PFE uses the token to identify packets of the multicast traffic to the child PFE during replication and forwarding of multicast packets proceeding according to the hierarchical forwarding structure.

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 σ or A and u are determined. The ratio μ/σ or A/σ 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： Samples from an addressed data forwarding devices, such as a router, are associated with path-centric information. Information from the samples is used to update corresponding path-centric traffic information, such as flow information for example. The aggregated path-centric traffic information can then be used by traffic analysis operations.

摘要： A biasing algorithm, apparatus and method for detecting and modulation format of a received signal used in a mobile phone system implementing EDGE technology that transmits and receives both GMSK and 8PSK modulated signals. The biasing method and apparatus may also estimate the modulation format of bursts of data blocks of a received signal using information gathered and/or results determined during the modulation detection of one or more previous bursts of a data block to bias the modulation detection of a present burst of the same data block. The gathered information during the modulation detection of a previous burst includes either the signal-to-noise ratio or the noise energy information of the previous burst.

摘要： Selection of proper virtual routing and forwarding (VRF) tables is based on a logical interface that is not associated with a physical interface. The selected VRF table is used to perform an output interface lookup for outgoing packets. In one example, a router includes a plurality of network interfaces, and a processing unit configured to select a logical interface not associated with any of the plurality of network interfaces based on an association with a received packet of a virtual private network, select one of a plurality of VRF tables in which to perform an output interface lookup for the packet that corresponds to the selected logical interface, and determine one of the plurality of network interfaces from the one of the plurality of VRF tables based on a destination of the packet, wherein the determined one of the plurality of network interfaces is configured to forward the 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.

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.
