SYMPHONY - A Controller Architecture for Hybrid Software Defined Networks

As enterprises migrate to SDN, a brown field network transitional state is inevitable, where both Software Defined and Legacy networks coexist. The aim of this work is to further the knowledge in the area of Hybrid Software Defined Network (SDN) networks, by investigating requirements and challenges involved in building such networks. This work proposes a Hybrid SDN controller architecture to establish, control and inter-domain communication between the legacy and SDN domains.
