Question

what is difference between virtual circuit switching and cicruit switcing?

Answer 1

Circuit Switching is like an acutal physical connection between the links .like the home phone.



virtual circuit switching/Packet Switching: sort of like routed over nodes etc.

Answer 2

Virtual Circuit Switching

Answer 3

In telecommunications, a circuit switching network is one that establishes a fixed bandwidth circuit (or channel) between nodes and terminals before the users may communicate, as if the nodes were physically connected with an electrical circuit.



The bit delay is constant during a connection, as opposed to packet switching, where packet queues may cause varying delay. Each circuit cannot be used by other callers until the circuit is released and a new connection is set up. Even if no actual communication is taking place in a dedicated circuit that channel remains unavailable to other users. Channels that are available for new calls to be set up are said to be idle.



Virtual circuit switching is a packet switching technology that may emulate circuit switching, in the sense that the connection is established before any packets are transferred, and that packets are delivered in order.

Answer 4

The main difference between Virtuall circuit and Circuit switching is that virtual circuit uses Identifier lineand circuit switching uses detected line
