The introduction of SDN in large-scale IP provider networks is still an open issue and different solutions have been suggested so far. In this paper we propose a hybrid approach allowing the coexistence of traditional IP routing with SDN based forwarding within the same provider domain. The solution is called OSHI – Open Source Hybrid IP/SDN networking as we have fully implemented it combining and extending Open Source software. We discuss the OSHI system architecture and the design and implementation of advanced services like Pseudo Wires and Virtual Switches. Moreover we designed and implemented a set of Open Source management tools for the emulation of the proposed solution over the Mininet emulator and over distributed testbeds. We refer to this suite of tools as Mantoo (Management tools). Mantoo includes an extensible webbased graphical topology designer providing different layered network “views” (e.g. from physical links to service relationships among nodes). The framework is able to validate a topology, to automatically deploy it over a Mininet emulator or a distributed SDN testbed, to access nodes by opening consoles directly via the web GUI. Finally, Mantoo provides tools for evaluating the performance of the deployed solution.
