Abstract: 

SDN needs to program heterogeneous forwarding elements (FE) with different forwarding architectures. Ideally, OpenFlow should provide a uniform interface to allow platform-independent programming and platform-specific compiling. In this paper we discuss an SDN programming framework which is suitable for flexible and protocol-oblivious forwarding plane. Specifically, we describe three different forwarding plane programming approaches and their tradeoffs. We show how an OpenFlow instruction set can support different programming styles which map to different forwarding chip architectures. We also show how applications can be compiled into NP-based FEs and compare it with the interpreter-mode implementation.
