Abstract

Since the current SDN southbound interface level is low and programming situation is complex, it requires a high-level abstract programming language to simplify programming. First, this paper improves the NetCore programming language to generate NetCore-M language, so that it can support deployment of multi-policies combination including packet drop action. This paper describes in detail the syntax, semanteme, and implementation of NetCore-M language. Secondly, this paper describes the network policy conflict systematically and solves it. Finally, this paper shows that the modified multi-policies combination algorithm can effectively detect and prompt policies conflicts based on the implementation of the Pyretic project.
