We present Ryuretic as a modular, programming framework for SDN application development. Ryuretic draws its inspiration from Pyretic, which already offers powerful, modular abstractions for network operators; however, Ryuretic also builds on Ryu's greater variety of packet match fields and its access to advanced OpenFlow protocols. This framework allows programmers to create new, extensible, and more powerful network applications at a much higher level of abstraction. As Pyretic does with POX, Ryuretic places an additional abstraction layer over the Ryu framework for network application development. Additionally, its abstractions allow researchers to target specific layers of the OSI model and install both proactive and reactive rule sets, without immersing themselves in the Ryu architecture. Ryuretic is under continual development, and it is available to users via GitHub.
