摘要: | A capacity assignment strategy for a broadband network is proposed and studied in this paper. This broadband network has a large channel capacity in its elements. It usually has two kinds of customers: one is queueable narrowband (NB), and the other is blockable wideband (WB) which needs real-time delivery. Besides the characteristics of these two types of traffic, since the improvement in the blocking probability of WB is more significant than that in the mean waiting time of NB, the capacity assignment strategy favours the WB traffic by providing bit-rate compression, reserving some channels for WB customers with non pre-emption by NB customers, and permitting NB customers to use free WB channels only when the NB queue exceeds a certain length. An analytic model is developed and the solutions are presented. The results show that, via proper choice of design parameters, the proposed strategy can have superior performance. |
