[dpdk-users] packet monitoring anc classfication

[Barbaros Kazan]

Hi all,
I want to make an application that makes packet classification according to the IP, sequence number etc.. like capturing packets with libpcap and making anomlay detection on the received packets.
So i need to generate traffic from various device that dont have pkt-gen.So with dpdk I need a tcp/ip stack. The kni interface example matches this, but this time after dpdk gives packet to kni, i need to capt
ure packets  with again tool like tcpdump using pcap.does not this make a performance issue?.I want to make the classification on the packets whenever dpdk takes them.For example, ip fragmentationt and ip multicasting and also ipsec apps are suitable for this i think.But this time there is no tcp/ip stack so i need to generate with pkt-gen. What is the best way to classify the packets that have been generated from different devices with different packet generators?
