Can you please specify what you're trying to do? Do you want to check all incoming packets on a specific socket or what else? – LucaMus Jan 08 '16 at 14:06

I made a similar application some years ago using WinpkFilter. I don't know if there is something better, but this gives you all that need to read all packets passing on network interface. Once you read the packets, you can check protocol type and make all operation you need to prevent DDOS.
You have to install the WinpkFilter driver and link the ndisapi.dll library, I suggest you to give it a try and see if this can help you.
