Difference Between Switched Virtual Circuits (svcs) And Permanent Virtual Circuits (pvcs)? |
|
Answer» Switched Virtual Circuits: Switched virtual circuits are dynamically established when data needs to be transferred and that are terminated when data TRANSMISSION is complete. SVCs consist of four STATES: call setup, data transfer, IDLE, and call termination. Permanent Virtual Circuit: Permanent Virtual Circuits are permanently established virtual circuits that operate in one of two states: idle or data transfer. When the PVC is idle, the connection between the DTE DEVICES is still active.
