摘要
传统的网络层中对于IPTV业务质量监测方法不能满足光接入网中的需求。因此,提出一种基于FTTH物理层光指标OSNR测量的IPTV服务质量监测的方法,通过对接入光信号OSNR的测量来监测IPTV业务的服务质量。仿真结果证明,上述方法通过监测OSNR能够IPTV接入业务的服务质量,从而提高光接入网络的运维效率,节省运维成本。
The methods of IPTV traffic monitoring in network layer can not meet the requirement in the optical access network.Therefore,a method of monitoring QoS for FTTH IPTV traffic based on OSNR measuring in physical layer is provided in this paper.The result of simulation certifies that the method mentioned above can monitor QoS for the access traffic efficiently,enhance the efficiency of network operation and maintenance,and save the cost of network operation and maintenance.
