DNS is hierarchial; DUNDi is not. Why do you say DUNDi isn't hierarchical? The notion of formal peering agreements forces a hierarchy (which may not be a simple tree like DNS, but will be a levelled hierarchy nonetheless), and caching of route data based on the TTL information makes it more efficient. > > DUNDi is not used for exchanging multi-megabyte media files - it's used > > for making very small routing requests. > > Gnutella's routing is also very small, but tons of routes adds up to big > bandwidth, as Gnutella found out. Nodes in a DUNDi network will know whether or not they are authoritative for certain number sub-spaces, and hence deployers can make appropriate decisions for bandwidth, CPU etc at each node. Contrast this to the GnuTella network where random nodes could find themselves coopted as crucial nexii in the network without warning, with sometimes very negative results. Again, this is like DNS - links between DUNDi nodes are created as a result of explicit peering agreements, rather than node links being randomly created by automatic exchange of node addresses.
