List of terms

ATM IP function processor

Nortel Multiservice Switch ATM node function processor that uses the Multiservice Switch queue controller (PQC) and ATM queue manager (AQM) ASICs to provide enhanced cell processing and ATM traffic management capabilities.

ATM layer

A layer in the B-ISDN protocol stack that transfers ATM cells. It is positioned between the physical layer and the AAL.

ATM link

A standards-based ATM connection.

ATM logical multicasting

Logical multicasting creates additional VCCs on the same output port of a node, thus allowing more than one replicated copy of the same cell to be delivered to the same output port. This in turn enables cell replication for transport over ATM networks that do not support multicasting.

ATM multiprotocol encapsulation service

A service that supports two encapsulation methods for carrying connectionless network interconnect traffic over AAL-5. The first method is logical link control (LLC) encapsulation, which permits multiple protocols over a single ATM virtual circuit (VC). The second method is VC encapsulation, which permits one protocol over each ATM VC.

ATM network multicasting

Network multicasting is performed at each node in the ATM network to determine where branch points for a PMP call are required. Once a branch point is identified, spatial multicasting techniques are utilized to replicate the cell stream.

ATM networking

Encompasses the standards-based UNI, IISP, AINI, and PNNI routing and signaling protocols.

ATM queue manager (AQM)

A hardware chip on ATM IP function processors. The AQM performs traffic management functions such as per-VC queuing, shaped fair queuing, and processing for available bit rate (ABR) traffic.

ATM spatial multicasting

Spatial multicasting delivers replicated cells to different output ports on the same node, thus permitting the routing of cells from the same node to different destinations.
