摘要

大规模部署IPTV涉及多个网段，从原始视频内容服务器到机顶盒。每个网段都可能容易出错。QoS监控和故障排除是保证用户体验满意的关键。在本文中，我们讨论了AT&T U-Verse(世界上最大的IPTV部署之一)中的QoS监控和故障排除。我们介绍了U-Verse的整体架构，重点是QoS。此外，我们回顾了当前U-Verse在QoS监控和故障排除方面的努力，以及它们的挑战和机遇。此外，我们还提供了一个案例研究，说明如何使用当前QoS监控和故障排除基础设施收集的数据对U-Verse IPTV系统进行故障排除。

QoS Monitoring and Troubleshooting of a Large Scale IPTV Deployment

Several network segments are involved in a large scale IPTV deployment, from the original video content server to the set-top-box (STB). Each network segment could be error-prone. QoS monitoring and troubleshooting are critical to guarantee satisfying user experience. In this paper, we discuss QoS monitoring and troubleshooting in AT&T U-Verse, one of the largest IPTV deployments in the world.We present the overall architecture of U-Verse, with a focus on QoS. Furthermore, we review the current efforts in U-Verse on QoS monitoring and troubleshooting, as well as their challenges and opportunities. Moreover, we provide a case study on how to troubleshoot the U-Verse IPTV system with the data collected by current QoS monitoring and troubleshooting infrastructure.
