Re: PVC vs. SVC (frame relay) Hello, basically, a PVC is a permanent point-to-point circuit between two predetermined endpoints, while an SVC is a connection that can be set up between any two users, provided these users have an access connection.

Frame Relay is a standardized wide area network technology that specifies the physical and data link layers of digital telecommunications channels using a packet switching methodology. Originally designed for transport across Integrated Services Digital Network (ISDN) infrastructure, it may be used today in the context of many other
