如何使用Apache Spark捕获数据包并分析SDN网络

I am new in the world of network. I work in SDN field and I have a POX controller with a mininet. I need to capture the packets in the network using Apache Spark and then analysis them. By now I use Wireshark to capture packets and do analysis on them in Spark. However I think that Spark itself has capability of capturing the streaming packets. I search on this topic but unfortunately I could not find a good and clear code or method on it. Can any body help me more clearly?I am new in the world of network. I work in SDN
