Abstract

Today many services over the networks, e.g., IPTV(Internet Protocol TV), web-based services are introduced to extend the business area of telcos( telecommunication companies). Therefore fault localization technique should be enhanced to cover the application layer. In this paper, we propose the rule-based alarm correlation method with functional event separation. And we also suggest modeling strategy for service resources and functional dependencies to enable those techniques. The proposed service fault localization method enables end to end service fault localization including application layer with less complexity and we prove it by implementing the pilot system for representative fault cases of real IPTV services.
