Abstract
According to one embodiment, the invention is directed to a facility for providing Asynchronous Transfer Mode (ATM) and Internet Protocol (IP) Quality of Service (QoS) features in a digital communication node. The facility includes a plurality of logical input ports, a plurality of logical output ports, ATM switching elements, IP routing elements and QoS elements. The switching and forwarding elements transfer ATM data cells and IP data packets from the logical input ports to the logical output ports. The QoS elements prioritize, schedule and flow control the transfer of data, based at least in part on ATM QoS features associated with the ATM data cells and on IP QoS features associated with the IP data packets.
