Managing service level delivery is challenging, typical case in IMS network with multiple service and users. The IMS as control layer must perform end-to-end services with a guarantee to secure and manage anomalies due to the network diversity, however the network performance is dynamic and the amount of useful information is limited so it's difficult to detect problems after supply before they surface. The IMS to fulfill service monitoring must use the eTOM (enhanced Telecom Operations Map) Framework, That tool can simplify integration, supervision and monitoring over a new telecommunications network. IMS have to provide a guaranteed Quality of Service (QoS) to the users in the case of VoD service, the providing procedure respect QoS standards and enter into fulfillment processes although remains assurance and billing, for that we propose a monitoring system-based eTOM that retrieve supply information in real-time and simulate the business operation with distributed WSOA concept. Furthermore, set of information retrieved will be used in SLA (Service Level Agreement) verification, take corrective actions, and predicate service-level impact.
