Fair Queuing - Part 2

The animated TECHTip Tutorial is available here.

Part I - FQ [Fair Queuing] allocates bandwidth to each packet that crosses the interface based on a FIFO [First-In First-Out] also called RR [Round-Robin] - bit-by-bit equal access basis. That is, no packet receives Priority Queuing. Weighted Fair Queuing Scheduler allocates bandwidth to each packet based on “weights” (values) determined by the administrator.

Part 2 - FQ assigns equal priority on all packets. However, Weighted FQ assigns priorities on groups of packets called conversations such as an FTP [File Transfer Protocol] or HTTP [HyperText Transfer Protocol] session. The term conversation is used to indicate a sequence of packets such as a voice conversation which would ideally not be routed word by word.
