The emergence of Software-Defined Networking(SDN) has led to a paradigm shift in network management. SDN has the capability to provide clear and easy management of complex operational challenges in large scale networks. However, most of the existing work in SDN network management assumes a full deployment of SDN enabled network switches. Due to both practical and financial limitation real implementations are likely to transition through a partial deployment. In this paper, we describe our experience in the design of HybNET a framework for automated network management of a hybrid network infrastructure (both SDN and legacy network infrastructure). We discuss some of the challenges we encountered, and provide a best-effort solution in providing compatibility between legacy and SDN switches while retaining some of the advantages and flexibility of SDN enabled switches. We have tested our tool on small hybrid network infrastructure, and applied it to manage the OpenStack Neutron interface a well known open-source IaaS provider.
