Hi Alfredo If i want to do it in my own code, what method or data structure i could use to easily retrieve the received packet's from IP, port, protocol?
Secondly, if i do it in my own code , and i just need to filter the multicast protocol, and a specific range of ip and port, would this use case be still faster than using method like unix epoll? I am asking this because in this use case I am capturing all the packets from the device, and filtering only the subset of what i need in my code.

Hi Bryanpf_ring provides raw capture, you should handle your traffic writing your own code, if you just need to filter some traffic you can use bpf or similar.

I am following the zcount.c example under /PF_RING-master/userland/examples_zc folder. So far so good until where can I define the mulicast group address and port in the code? or should it be define in the file? I have about 30 multicast group need to be listen.
