Switched Virtual	An ATM standard signaling protocol that automatically defines
Connection (SVC)	connections as they are needed, and discards them when desired.
topology	The physical or logical placement of stations on a network in relation to
	one another.
Virtual Channel	Part of the identifier of a particular virtual circuit in the ATM fabric.
