In this paper we study a way to exclude the necessity for proactive Service Function (SF) path policy from Service Function Chaining (SFC) classification process. SFC architecture uses network traffic classification for steering network traffic through SF path. Architecture does establish overall requirements for classification but is unable to dynamically discover SF paths. Therefore, we propose a reactive SF path discovery method. Reactive SF path discovery gains an advantage over proactive discovery by use of reclassification for unknown network traffic. We examined our method in a Software Defined Network (SDN) emulation in Mininet emulator with RYU SDN controller. The result of this study is a comparison between proactive and reactive SF path discovery, which shows that our SF path discovery method has higher probability of successful SF path discovery.
