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
ATM link
A
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
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

ATM queue manager (AQM)
A hardware chip on ATM IP function processors. The AQM performs traffic management functions such as
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.
