Question

How Virtual Circuit Approach works?​

Answer 1

$\huge{\boxed{\underline{\bold{Answer:)}}}}$

$\huge{\underline{\bold{Virtual\: Circuit\:Approach}}}$

→ Route is established.

→ Packets forwarded from one node to the next using store-and-forward scheme.

→ Only the virtual circuit number need to be carried by a packet.

♦ Each intermediate node maintains a table.

♦ Created during route establishment.

♦ Used for packet forwarding.

→ No dynamic dynamic routing decision is taken by the intermediate notes.
