监视网络性能参数的变化是实现 ATM网络 Qo S管理的一个关键 .但是 ITU - T定义的 OAM性能管理功能只简单地监视网络性能、产生报告信息 ,而不能对 Qo S的管理提供足够的支持 .本文为此在讨论 Qo S和网络性能参数的基础上 ,设计了一个 ATM网络的 Qo S管理模型 .其中 ,对 OAM性能管理功能进行了改进 ,一些满足 Qo S管理需求的 ATM网络性能监测功能在 OAM信元的保留字段中得以实现 . However, the OAM performance management function defined by ITU-T simply monitors network performance and generates report information without providing enough support for Qo S management. In this paper, based on the discussion of Qo S and network performance parameters, a Qo S management model for ATM network is designed, in which OAM performance management functions are improved, and some ATM network performance monitoring functions that meet Qo S management requirements OAM cell reserved field to be achieved.
