What are the queuing mechanisms?
There are typically three methods of queuing: FIFO (First in First Out) – FIFO queuing is a strict queuing method of transmitting packets in the order in which they are received. CBQ (Class Based Queuing) – A queuing methodology in which traffic is divided into classes and separated into queues according to the assigned class. WFQ (Weighted Fair Queuing) – WFQ allows multiple queues to be defined for multiple traffic flows. The administrator creates different queue sizes and delegates what traffic is destined for a particular queue. In addition to the 3 basic queuing mechanisms, Asce Networks’ NeuTrans utilizes advanced queuing methodologies for Cisco, Juniper and Nortel Networks etc. routers that combine characteristics of the basic types. Examples of these mechanisms are; CQ (Custom Queuing), PQ (Priority Queuing), CCBQ (Custom Class Based Queuing) and CBWFQ (Class Based Weighted Fair Queuing).
