Scalability management for virtualized IMS
IP multimedia subsystem has been identified by mobile network operators as a promising framework for deploying VoLTE and rich communications services. Offering these services in efficient manner makes it even more attractive. Virtualization represents the suitable concept to achieve this. Moreover, deploying IMS in virtualized environment becomes a solution of great potential especially for multi-tenant application providers. This project aims at defining and validating elasticity management approaches of virtualized IMS based on SLA. These approaches will help Mobile network operators and multi-tenant application providers to offer better performance and overall service experience.
