'''Class-based queuing''' (CBQ) is a queueing discipline for the [[network scheduler]] that allows traffic to share [[Bandwidth (computing)|bandwidth]] equally, after being grouped by classes. The classes can be based upon a variety of parameters, such as priority, interface, or originating program.

'''Class-based queuing''' ('''CBQ''') is a queueing[[queuing discipline]] for the [[network scheduler]] that allows traffic to share [[Bandwidth (computing)|bandwidth]] equally, after being grouped by classes. The classes can be based upon a variety of parameters, such as priority, interface, or originating program.

CBQ is a traffic management algorithm developed by the Network Research Group at Lawrence Berkeley National Laboratory as an alternative to traditional router-based technology. Now in the public ___domain as an open technology, CBQ is deployed by companies at the boundary of their WANs.

Line 9 ⟶ 11:

Because it operates at the [[Internet Protocol|IP]] network layer, CBQ provides the same benefits across any [[Data link layer|Layer 2]] technology and is equally effective with any IP protocol, such as [[Transmission Control Protocol]] (TCP) and [[User Datagram Protocol]] (UDP). It also operates with any client or server TCP/IP stack variation, since it takes advantage of standard TCP/IP flow control mechanisms to control end-to-end traffic.
