  • Method for weighted fair queuing for ATM cell scheduling
    Patent number: 6014367
    Abstract: A method is provided for the implementation of a fair queuing ATM cell scheduler that can precisely pace virtual channel (VC) traffic by an assigned weight which defines the available bandwidth to be allocated to that VC. The method provides a minimum service rate to each virtual channel on a small, selected time scale, and requires only a small, bounded amount of work per physical connection, independent of the number of VCs.

  • Digital comparator circuit
    Patent number: 5260680
    Abstract: A comparator circuit is provided that determines whether a given value is within a selected compare range. The comparator circuit electronically implements a Ling Adder algorithm to perform comparisons. The circuit operates at a high speed and requires fewer components compared to circuitry implementing a conventional carry look ahead algorithm. The circuit may be implemented in CMOS technology.
