A varying arrival rate Poisson batch ( VARPB) process is used to approximate the input process of a statistical multiplexer and a VARPB/ D/ 1 queue model is obtained. The queue length distribution and waiting time distribution are derived. 采用变到达率泊松批量(VARPB)过程逼近统计复用系统的输入过程,形成了VARPB/D/1排队模型,求出了队列长度的分布和等待时间的分布。
Application of statistical data multiplexer ( MUX 402) to bank business data network 统计式数据集中器(MUX402)在银行数据业务网中的应用
This article introduces some new equipment of DTV head-end, such as statistical multiplexer, statistical re-multiplexer, QAM modulator with multiplex and scramble function, multi-protocol DS-3 to ASI bidirectional adapter. It also describes how to construct head-end using these equipment. 介绍一些新型数字电视前端设备,例如,统计复用器,统计再复用器,带复用加扰功能的QAM调制器以及多协议的DS-3到ASI双向适配器,并且讲述如何利用这些设备构建前端。
