| Abstract | The calls that require high bandwidth and low blocking probabilities are difficult to provide so it is natural to book the network requirement ahead of their actual use to reduce their chance of service denial. A modification of a scheme for sharing resources among wide band book-ahead (BA) calls and narrow band non-BA calls based on equivalent bandwidth approach is proposed in this study. Moreover, it may be desirable to allow some calls that do not book ahead to be interrupted to achieve a more efficient use of resources. In the analysis, one resource is shared by BA and multiple classes of instantaneous-request (IR) calls with the upper bound limitation. In the simulation, the admission control admits a call if an approximate interrupt probability is below a threshold in each class. The interrupt probability calculation is based on IR call termination probabilities and the time dependent traffic distribution of BA calls. Comprehensive analysis in resource sharing with upper bounds provides understanding of the efficiency to protect the overloads and how book-ahead effects call blocking. Simulation experiments show that the more service interruption for IR calls the lower blocking probability of themselves. |
