[c-nsp] Duplicate the packets

[Oliver Boehmer (oboehmer)]

Can you elaborate on the application requirement at hand here? Not losing a single packet is virtually impossible in IP networks, you will always have failures/re-routing events, or also things like dropping packets while ARP adjacencies are resolved along the way, so I would argue that a potential initial set-up delay due to joining a group is the least concern. 
If you need guaranteed delivery, look at protocols like SCTP/Sigtran, along with diverse paths through the network.

Multicast takes time when it goes out of GROUP and joining GROUP. i dont want to lose even a single packet.

hmm, multicast comes to mind?
