DDOS

In a decentralized system of privacyServer nodes using UDP where is the DDoS attack vector? The directory info is broadcast via the various coin networks. Unlike TCP where you can lock up a socket for a while, with UDP there are no connections to tie up, so you have to saturate the entire channel. If the attacker has resources to DdoS all the nodes of SuperNET and simply saturate everybody's connection, I see no solution to this. Then again what is the cost of this and what is gained?

So, if somebody will be saturating 100,000 nodes with 100,000 x 1 mbit/sec = 100 terabits/sec of flood traffic, expect SuperNET to have some slow response time for a while. If the attacker has 1 petabit/sec of bandwidth, then the SuperNET will be taken offline for the duration, then again so will all the coin networks and a big chunk of the Internet itself.

If anybody can make some hypothetical attack vectors based on the actual SuperNET design, I would appreciate this. For the initial version, I am just thinking that getting a "busy" signal is acceptable in the event that the other node is not reachable for whatever reason. I dont expect the SuperNET to be subjected to the petabit/sec flood in its first months.
