| Abstract | A major part of the traffic in the ATM based B-ISDN is produced by multimedia sources like teleconferencing terminals and video-on-demand servers. The calls that require high bandwidth and low blocking probabilities are difficult to provide. As a result, it is natural to book the network requirement ahead (Advance Reservation) of their actual use to reduce their chance of service denial by reserving the resources for VBR wide band traffic calls in advance. Moreover, it may be desirable to allow some calls that do not book ahead to be interrupted to achieve a more efficient use of resource. To serve both VBR Book-Ahead (BA) calls and instantaneous request calls the resource can be partitioned into two disjoint subsets dedicated to each class or the resource could also be shared. Two classes of instantaneous request (IR) calls are considered. We consider VBR traffic in the Call Admission using effective bandwidths. For our effective bandwidth calculation, the aggregate arriving traffic to calculate the effective bandwidth is modeled by a two-state Markov modulated Poisson process (MMPP) by matching of mean arrival rate, peak to mean ratio, auto-covariance time coefficient, and variance. We propose the Call Admission Control scheme that can dete1mine the interrupt probability oflnstantaneous Request Calls considering the VBR traffic calls. The admission control admits an instantaneous-request call if its approximate interrupt probability does not exceed the interrupt probability threshold. The interrupt probability calculation is based on IR call termination probabilities and the time dependent traffic distribution of Book-Ahead calls |
