摘要
本文针对ATM技术在卫星网络中的应用,就如何实现卫星频率资源的分配,以提高全网统计复用的增益,降低信元的丢失率,提出了一种新的排队模型:二级队列共享。并根据卫星信道的特点,采用混合多址方式TDMA/CDMA,实现二级队列资源共享。最后对话音信源模型(ON/OFF模型)在该共享方式下的性能作了计算机模拟,并给出了有关结论。
The paper presents a new method, two-stage queueing model for resource sharing,to improve the efficiency of bandwith and to decrease cell loss rate in satellite ATM network.This model can also provide an easy management for satellite resource. A mixed multiple access TDMA/CDMA is put forward for this mode. The voice model(ON/OFF model)results under this model is simulated and some conclusions are given.
