Skype claims to have a scalable, secure, globally distributed directory of
Skype phone numbers they call the "Global Index". From the Skype FAQ:
"P2P network technologies used by file-sharing applications would be almost
suitable for decentralizing [phonebook directories], but those networks are
fragmented in nature a search does not reach all nodes in the network.
Clearly, in order to deliver high quality telephony with the lowest
possible costs, a third generation of P2P technology (3G P2P), or Global
Index (GI) was a necessary development and represents yet another paradigm
shift in the notion of scaleable networks. The Global Index technology is a
multi-tiered network where supernodes communicate in such a way that every
node in the network has full knowledge of all available users and resources
with minimal latency. "
Does anyone know what techniques Skype might be using to actually achieve this?
