ATM 网络物理层信元插入的 CDV 及其容限
CDV and Its Tolerance of Physical Layer Cell Insertion in an ATM Network
【摘要】 源流量点和UPC控制点间的信元延迟变化(CDV)对ATM网络的资源分配、CAC和UPC控制都有着重要的影响.在文献基础上,进一步讨论了基于信元接口的ATM网络物理层(PL)信元插入的情况,研究了信元时隙映射和PL信元插入联合作用下的CDV,提出了不同序列不同信元的CDV计算公式,并确定了CDV容限.示例表明:公式计算与定义结果是一致的.
【Abstract】 The cell delay variation (CDV) between the source traffic point and UPC control point has a significant impact on the resource allocation, CAC and UPC control in an ATM network. On the bsasis of the work in Ref., the case of physical layer (PL) cell insertion in an ATM network with a cellbased interface is discussed and the CDV under the joint effect of cell slot mapping and PL cell insertion is investigated. The computing formulae for CDV with different arrays and different cells are proposed and the CDV tolerance is determined. The example shows that the results of calculation by the formulae proposed are in agreement with those by definition.
【Key words】 time slot; cell mapping; cell delay variation (CDV); CDV tolerance; physical layer cell;
