摘　　要：设计了一种基于低成本IP反射器的分布式NGN承载网性能评估系统,部署在NGN承载网络的不同级网络设备之间,对IP网络的不同性能指标进行实时监测,并对网络服务质量(QoS)进行评估。基于FPGA实现的低成本IP反射器很好地实现了对网络性能参数的实时采样测量。本系统设计可维护、可管理、可升级。A distributed NGN carrier network performance evaluation system based a low cost IP reflector is proposed in this paper. Reflectors can be among different network devices of different network layers.Most performance features of IP network can be monitored in real time and then the QoS is evaluated.Low cost IP reflector is designed using FPGA and it is well deployed to sample the performance parameters.The evaluation system is easy to maintain,manage and update.
