Question

In virtual circuit network, the number of delay times for setup and teardown respectively are _______

(a) 1 and 1

(b) 1 and 2

(c) 2 and 1

(d) 2 and 2

I had been asked this question in unit test.

My enquiry is from Virtual Circuit in portion Frame Relay of Computer Network

Answer 1

Correct option is (a) 1 and 1

To explain I would say: There is one-time delay for both setup and teardown phase. The one-time delay in setup phase is for resource allocation and the one-time delay in teardown phase is for the de-allocation of the resources.
