Distributed network monitoring for IMS network

The IMS (IP Multimedia Subsystem) network as a new generation suffers of traditional Internet problems such as managing and monitoring QoS which have a direct impact on the the operator´s revenue streams. Among solutions proposed, the eTOM (enhanced Telecom Operations Map) published by the TM Forum and 3GPP specifications will be sufficient to describe a system for monitoring and managing QoS. Moreover, the most of the monitoring architecture is centralized at the level of processing performance data, which make monitoring much more difficult and very slow operation and with less effective against the problems. In this paper, we propose a distributed architecture eTOM-based for IMS monitoring, and as use case the SLA verification scenario for multimedia services like VoD (Video on Demand).
