Abstract
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 connection until the connection exceeds its fair share of resource utilization.
