A method and apparatus for providing differentiated services using a multi-level queuing mechanism includes checking whether a packet of data is to receive a preferred level of service, and if the packet is not to receive the preferred level of service, then placing the packet in a first forwarding queue. However, if the packet of data is to receive the preferred level of service then checking whether it is permissible to forward the packet to a device in the network at the current time. If it is permissible to forward the packet to the device at the current time, then placing the packet in a second forwarding queue, otherwise temporarily placing the packet in a holding queue before placing the packet in the second forwarding queue.
