VPC

virtual path connection

A VPC is a series of linked VPs that extend between the point where the VCI values are assigned and the point where those values are translated or removed.

A VPC carries VCCs between sites. VPC traffic is carried on full ATM trunks. VPCs use physical bandwidth only when the end devices pass traffic over the network; they do not use bandwidth if there is no data to transmit.

A VPC is a concatenation of VP links. The endpoints of a VPC are the points at which the ATM payload is passed to, or received from, the users of the ATM layer.
