1.4 Virtual Circuit
Some network protocols create virtual circuits in networks. A virtual circuit is conducted through the network and all packets of a particular connection go via the circuit. If the circuit gets interrupted anywhere, then the connection is interrupted, a new circuit is established, and data transmission continues.
Figure 1.16: Virtual circuit
In the figure above, a virtual circuit between nodes A and D is established via nodes B, F, and G. All packets must go through this circuit.
Datagrams can be transmitted via the virtual circuit in two ways:
- The circuit does not guarantee the datagrams delivery to its destination. (If network ...
