N2 - Software-defined networking (SDN) changes the structure of core networks from statically planned to flexible and adaptable to the network conditions. The de facto standard for the interaction between the controller and the forwarding devices (e.g., SDN switches) is the OpenFlow protocol. With increasing interest in SDN technologies, researchers found solutions to extend these paradigms to end devices, like it is done with the protocol virtualization framework VirtualStack. However, the current SDN protocols such as OpenFlow are unsuitable for controlling end devices, since they are designed for core network nodes. In this paper, we close this gap by presenting TROLL - a protocol suggestion for realizing software-defined control at the network edge. With the communication between the controller and the VirtualStack-enabled end devices being defined by TROLL, control decisions can be made jointly for both the network core and the edge, improving the flexibility, adaptability, and efficiency of the network system significantly.
