The new INQA approach (IMS Network QoS Architecture) for IMS network (IP Multimedia Subsystem) monitoring, provides innovative solutions for management and monitoring services, in real time. This approach aims to change the reliability of services deployed by operators in a multi technological context which raises many challenges. However, the deployment costs of management entities are significant, particularly in terms of execution time and resources load. To this end, we propose in this paper a comparison between the deployment costs via both CORBA and SOA technologies, in order to identify the most appropriate one for monitoring IMS networks.
