| 摘 要： | 在卫星通信系统中,支持分组业务是发展趋势,而提供分组业务要求合理地规划网络的接口传输带宽,规划一般都根据用户的平均带宽需求来进行,并且做出一定比例的带宽预留.本文针对泊松业务源,从概率分析的角度来解释业务总量超过分配带宽的概率与带宽预留比例之间的关系,为如何得到适当的带宽预留比例提供了理论参考.

| Abstract: | It is a trend that packet service will be applied in satellite communication network. To provide such service, the transmitting bandwidth must be planned properly according to the average bandwidth requirements of the users, and a bandwidth preservation proportion should also be assigned. In this paper, the relationship between bandwidth preservation proportion and the probability of service traffic in excess of assigned bandwidth is analyzed from the perspective of probability theory for Poisson service source, providing the reference for how to assign proper bandwidth preservation proportion. |
