Hybrid networks contain both legacy and programmable network switches and allow operators to reap the benefits of Software-defined networking (SDN) without upgrading the entire network. Previous research shows that adding SDN capabilities to switches at strategic places in a network and ensuring that each flow traverses at least one such switch is sufficient to achieve many SDN control paradigms, such as routing or access control. However, the control points are still limited to the SDN-enabled devices and operators cannot enforce fine-grained policies on the legacy paths between SDN switches.
