In this paper, we propose two probabilistic modeling methods for IPTV network diagnosis, namely intolerable quality detection and device alarm analysis. The proposed methods can provide auxiliary information during troubleshooting processes, as well as inferring problematic devices automatically. Experimental results show that our models can distinguish problematic devices from normal ones and are...
This paper proposes a model to derive an overall assessment index of the quality for IPTV network in order to make the network faults diagnosis more efficiently. This paper also provides a systematic approach to estimate the quality index based on the packet loss events. This model has been applied to the actual operational environment, not only to regularly monitor the customer perceived quality,...
