Why are Frame Relay paths referred to as virtual?

  • There are no dedicated circuits to and from the Frame Relay carrier.
  • Frame Relay PVCs are created and discarded on demand.
  • The connections between PVC endpoints act like dialup circuits.
  • There are no dedicated circuits inside the Frame Relay carrier cloud.

Explanation: Unlike leased lines, there are no dedicated circuits in the carrier’s Frame Relay network for end-to-end customer connectivity. Most providers use PVCs (some use SVCs) to create and discard circuits as customers purchase them without needing to deploy additional cabling.
