9.3 Queuing Algorithms
-
Common Algorithms:
FIFO: Simplest method; packets sent in arrival order. No prioritization — may cause delay for critical traffic.
WFQ: Allocates bandwidth fairly among flows based on weights. Provides different priority levels automatically.
-
LLQ: Combines CBWFQ with a priority queue for real-time traffic (voice, video). Ensures minimal delay and jitter.
