Software-Defined Networking (SDN) essentially decou- ples the hardware from the software that controls it. Currently some SDN abstractions are materialized by OpenFlow and several OpenFlow controllers, based on different programming paradigms and architectures, are available. Usually these con- trollers are bundled with some sample applications that enables the construction of new ones by using their particular way. However these applications focus on specific services being tightly coupled with the switch behavior. In this scenario, SDN community is working to build a SDN control layer that meets carrier grade requirements such as throughput, availability and scalability. This work proposes a new SDN controller architecture that is integrated with a carrier grade service level execution en- vironment, based on the JAIN SLEE specification. The proposed approach extends SDN based services by integrating OpenFlow with several network resources and communication protocols providing a cross layer platform that can satisfy these telecom operators requirements.
