SLA management & monitoring based-eTOM and WS-composite for IMS networks

International audienceThe scope of IMS QoS management is limited to session initialization and QoS provisioning, thus lacking follow-up or monitoring functionality; neither does it tackle user differentiation. A tempting approach would be to leverage the standard 3GPP architecture by Assurance services based on TMForum's eTOM framework. This scenario would however expose a set of general business processes and would require a projection of IMS processes towards the eTOM. The work presented here follows this strategy, providing monitoring functionality to IMS services based on eTOM processes able to provide SLA assessment and Assurance services. The distributed architecture involves the BPEL language for orchestration and SOA component

WS-composite for management & monitoring IMS network

International audienceThe 3GPP standards for IMS (IP Multimedia System) provide access to multimedia services with robust procedures for QoS management. However its scope is limited to session initialization only, thus lacking follow-up or monitoring functionality; neither does it tackle SLA (Service Level Agreement) differentiation. A tempting approach would be to leverage the standard architecture by assurance processes based on TMForum's eTOM framework. This scenario would however necessitate a set of general business processes and would require a projection of IMS processes towards the eTOM. The work presented here follows this strategy, providing IMS services monitoring functionality based on eTOM processes able to provide SLA assessment and Service Assurance. It uses the BPEL language for orchestration and SOA elements to implement the distributed architecture

eTOM business processes conception in NGN monitoring

International audienceNetworks are growing in complexity because of several factors, including number of user, applications, and different technologies. Indeed the management in this case is relativistic. The QoS management mechanisms proposed by 3GPP allow providing the IMS network entities controls and efficient service delivery; however the 3GPP approach focuses entirely on the step of providing the service without consideration the type of customer, which requires a monitoring architecture. Furthermore the TMForum groups within specification scenario type of monitoring based end to end business process oriented Assurance to a permanent monitoring of the services provided. However these scenarios are generic and haven’t specification for IMS networks. We propose in this paper a new approach to monitor IMS networks, which based specifications TMForum and use WS-Composite and XML Communication, and it provides a platform for continuous monitoring of service
