Establishing a real time VBR connection over an ATM network

The conclusion of this paper flows from the principle of delay constancy. To achieve and maintain the delay constancy in the face of variable transfer delay, a pad-out buffer is used at the destination and the consumption of the first cell is delayed by a determinable amount. We examine the conditions under which the continuity throughout the session is preserved. We also conclude that the transfer of a real variable bit rate application by a deterministic bit rate transfer capability will be indistinguishable from a transfer by a statistical bit rate transfer capability
