Question

Which of the following features is true regarding concatenated virtual circuits?

• A. A sequence of virtual circuits is set up form source through one of more gateways to the destination
• B. Each gateway maintains table telling which virtual circuit pass through it
• C. The scheme works best when all the networks have roughly the same properties
• D. All of the above

Answer 1

Answer: (D)

All of the above

Virtual circuits:-

1) A sequence of virtual circuits is set up form source through one of more gateways to the destination

2) Each gateway maintains table telling which virtual circuit pass through it

3) The scheme works best when all the networks have roughly the same properties

A virtual circuit is a means of transporting data over a packet switched computer network in such a way that it appears as though there is a dedicated physical layer link between the source and destination end systems of this data.
