ATM网络信元时隙映射的CDV及其容限

CDV AND ITS TOLERANCE OF CELL SLOT MAPPING IN ATM NETWORK

源流量点和ＵＰＣ控制点间的信元延迟变化（ＣＤＶ）对ＣＡＣ，ＵＰＣ的控制有着重要的影响．文中在分析ＣＤＶ成因的基础上，研究了基于信元接口的ＡＴＭ网络信元时隙映射的ＣＤＶ，提出了ＣＤＶ的计算公式和一些结论，并确定了ＣＤＶ容限．

The cell delay variation (CDV) between source traffic point and UPC control point has important impact on the control of CAC and UPC. The CDV of cell slot mapping in cell based interface ATM networks is studied after analyzing the generating cause of CDV. The computing formulae and some conclusions of CDV are presented and the CDV tolerance is determined.
