Ummm...no, it's not even close to being basically the same as Gnutella. If anything, it's closer to DNS. DUNDi is not used for exchanging multi-megabyte media files - it's used for making very small routing requests. ..delete > Memory to store all routes shouldn't be a problem, one BGP4 full feed takes > only 50MB, > and thats about 130'000 routes... VoIP number spaces are much bigger than that. Consider storing a directory of every phone number in the US and you will see the problem. In any case, I expect that internal nodes in a DUNDi network would certainly cache portions of the data, based on the time-to-live data. Again, think DNS. Also consider that a small hand-held device may have memory measured in kbytes, and you see why assuming every node can store every entry is not a design requirement.
