the Permanent Virtual Circuit and the Switched Virtual Circuit. The latter has an advantage over the former. But
to a great extent
whether the SVC can be accepted by users
is determined by whether the SVC signaling is efficient
flexible and reliable. The paper describes the point to point SVC signaling protocol Q. 2931 and the point to multipoint SVC signaling protocol Q. 2971 at the user network interface. Then
it lays the author’s finger on the limitation of the SVC signaling today.
