John Pillar, Bernard Marchand, Bernard St Denis: Inter-class schedulers utilizing statistical priority guaranteed queuing and generic cell-rate algorithm priority guaranteed queuing. Nortel Networks, Gibbons Del Deo Dolan Griffinger & Vecchione, August 20, 2002: US06438106 (94 worldwide citation)

Inter-class schedulers for digital link systems provide high efficiency utilization of limited bandwidth by employing queuing techniques referred to as Statistical Priority Guarantee Queuing (SPGQ) and Generic Cell-Rate Algorithm Priority Guarantee Queuing (GCRA-PGQ). SPGQ “elevates” the priority of ...

John Pillar, Bernard Marchand, Jacob Guttman, Sitaram Patro: Scheduler implementing weighted fair queuing by a weight limited first in-first out methodology. Nortel Networks, Gibbons Del Deo Dolan Griffinger & Vecchione, December 31, 2002: US06501762 (15 worldwide citation)

Scheduler methods and apparatus utilize a weight limited FIFO (WLF) method to provide weighted per-connection queuing while maximizing preservation of cell arrival order, thus minimizing additional cell delay variation (CDV) added during scheduling. The invention minimizes additional CDV of a connec ...
