Dear Murphy & KK, Thanks for your kindly reply and help. Just like KK mentioned, we might need an IGMP multicast. So, in this point, we must do something on NOX. That is, we need to implement a data structure that do the same thing as Group table for recording which ports have IGMP request. Is is right, please clear me!
