IMS and SDN-OPENFLOW collaboration

Abstract

IMS is a SIP protocol-based architecture deployed as an infrastructure for call, session and service management in future networks. IP Multimedia Subsystem (IMS) is a management architecture for next generation networks (NGN). It is expected that this network architecture provides new multimedia services in scenarios of converged networks. Software-defined networks (SDN) have emerged as an approach to promote network innovation comprising higher flexibility, programming, management and profitability capacity.

This paper aims at proposing IMS and SDN architectures collaboration in order to mitigate security problems in future networks. To do so, an open-source platform as a testing lab is deployed for teaching, learning and performance assessment of the main elements of this architecture.
