The introduction of new revenue-generating services like Internet Protocol television (IPTV) promises to bring to the end user a much more personal-ized communication and entertainment experience at an affordable cost. IPTV brings new features like video on demand (VoD), broadcast TV, and customized ad insertion, along with more traditional voice and data services whose realization requires a wholesale deployment of existing and new protocols and new network elements. Configuration, maintenance and troubleshooting of such networks, customized for each end user, are complex, and it is widely believed that providing diagnostics mechanisms is of substantial importance for rollout of IPTV. This paper describes research efforts at Alcatel-Lucent toward the definition and development of end-to-end diagnostics for IPTV architectures, comprising probes and mechanisms to detect problems in the network and to issue corrective measures. © 2008 Alcatel-Lucent.
