Table Visor: An Emulation Layer for Multi-table Open Flow Switches

This work demonstrates TableVisor, a proxy layer for the OpenFlow control channel, which emulates a multi-table switch towards the controller. TableVisor uses one single-table switch per emulated flow table and combines all devices with their specific capabilities to a feature-rich pipeline consisting of multiple tables. As the used switches can be chosen by use case specific requirements, even multi-table pipelines can be built that are currently not available in one single device.
