3Com 6416SW manual Type Virtual Connection, Connection Mode

The	3Com ONcore Switch	imbedded	Control	Point provides a complete set of functions
to control an ATM campus		network	and to	interconnect local ATM networks over ATM
wide	area networks.

The Control Point supports an extensive set of ATM connections, including:

Switched (SVC) and permanent (PVC)

Point-to-point and point-to-multipoint

Reserved Bandwidth (RB) and Available Bit Rate (ABR)

Note: The Available Bit Rate service will be available in future releases of the 6416SW module.

ATM	control	functions are fully distributed instead of being centralized. This means that
all	nodes	participate as peers in	the control algorithms. Due to	the	distribution of co
functions,		ONcore ATM networks provide	for availability, scalability,	and	growth.
