SPIDER: A Practical Fuzzing Framework to Uncover Stateful Performance Issues in SDN Controllers. (arXiv:2209.04026v1 [cs.CR])

Performance issues in software-defined network (SDN) controllers can have
serious impacts on the performance and availability of networks. We
specifically consider stateful performance issues, where a sequence of initial
input messages drives an SDN controller into a state such that its performance
degrades pathologically when processing subsequent messages. We identify key
challenges in applying canonical program analysis techniques: large input space
of messages (e.g., stateful OpenFlow protocol), complex code base and software
architecture (e.g., OSGi framework with dynamic launch), and …
