| Abstract | The future Broadband Integrated Services Digital Network (BI SDN) based on Asynchronous Tra n sfer Mode (ATM) concept will
require the efficient handling of a v e ry diverse mix of traffic.
Several important issues related to the quality of service
requirements by the user's need to be answered. Efficient use of
the available resources requires procedures for congestion control.
Connection Admission Control (CAC) is an important part of the
congestion control mechanisms in B-ISDN . CAC schemes suggested so
far have considered only the peak cell rate and the average cell
rate as the traffic parameters. Average burst l ength although found
to be a critical parameter has not been included as a parameter for
traffic estimation. The Three Parameter Scheme suggested by Chamila
[CHAMILA(1992)] uses the burst length as a third parameter . However
the use o f burst l ength involves the burst length distribution
which plays an i mporcanc r ole i n the cell loss probability . This
has been neglected by Chamila. This research work f ocuses on t he
inclusion o f burst length distribution as a parameter for traffic
estimation. It has been demonstrated that the burst length
distribution can be used to determine the worst case traf fie
situation. A new Connection Admission Strategy has been proposed
which uses the burst length distribution as a parameter along with
the peak cell rate, average cell rate and average burst length. It
is demonstrated that the proposed scheme provides a tighter bound
on the cell loss probability when compared to the Three Parameter
Scheme . The results of the study suggests that the burst length
distribution is a critical parameter effecting the cell loss
probability and its inclusion as a source traffic descriptor allows
us to obtain a higher multiplexing gain . |
