    摘要: Three dimensional RF tag signatures may be obtained from a three dimensional RF tag or multiple two or three dimensional RF tags so that information in addition to presence information may be obtained. In one embodiment, a three dimensional RF tag having two or more power coils disposed in non-coplanar planes enables the coils to experience different levels of excitation from an electromagnetic field. This information may be transmitted along with the RF tag response to enable the orientation of the RF tag relative to an RF tag reader to be determined. In another embodiment, multiple RF tags (either standard RF tags or three dimensional RF tags) may be used on a given article and a response signature from the article as a whole may be recorded. The three dimensional response signature thus collected may be compared with previous versions of the response signature to determine if the article has been altered.

    摘要: Various techniques for queue management based on random early detection (RED) are disclosed herein. In particular, a method for generating a drop probability for an incoming packet in a device having a queue to buffer packets between segments of a network is provided. The method comprises determining, upon receipt of an incoming packet, a size of the queue and determining an error based at least in part on a difference between the queue size and a threshold. The method further comprises determining a drop probability for the incoming packet based at least in part on the error and a constant gain factor. The constant gain factor may be based at least in part on a linearized second order dynamic model of the network.

    摘要: Label information used by a downstream LSR is mirrored on an upstream LSR. In particular, a copy of the label information database in the downstream LSR from LDP sessions is stored on the upstream LSR. The label information database and corresponding mirror are synchronized. The mirror is employed to facilitate recovery from control plane failure through comparison of the label information database with the mirror. For example, the intersection of the label information database and the mirror may be calculated and employed as the updated label information database and mirror.

    摘要: An improved buffer management process is disclosed wherein the buffer is shared among a plurality of packet queues. The improved buffer management process comprises computing a common queue threshold value based upon the aggregate size of the plurality of packet queues and a predetermined buffer threshold value. The common queue threshold value is then used to manage the size of each of the plurality of packet queues and thereby manage the buffer.

    摘要: A method of allocating bandwidth for transmitting upstream cells from a CPE unit to a BTS. The CPE determines arrival time information associated with each cell and sends arrival time information associated with at least one cell to the BTS. The BTS allocates future bandwidth to the CPE as a function of the arrival time information received from the CPE. For example, the BTS estimates the number of cell arrivals occurring in the current scheduling period based on past cell arrival times. The BTS then sends information to the CPE in which the allocated future bandwidth is specified. Finally, the CPE groups a number of cells into a burst packet occupying the allocated bandwidth and sends the burst packet to the BTS. Rather than respond in a delayed manner to a bandwidth deficiency or surplus at an individual CPE unit, the BTS produces an estimate of a CPE unit's bandwidth demands, resulting in more efficient bandwidth utilization and reduced cell loss ratio.

In one embodiment, the first circuit board has a substantially rigid circuit portion having a plurality of circuit layers, including a first signal layer, and a first interconnection portion, including the first signal layer, for mating with a second interconnection portion of the second circuit board.
