Internet Sibilla Distributed applications are popular in todays Internet. » Peer-to-peer file sharing, CDNs, multi- player online games These applications benefit from the information about the network-internal performance characteristics. » Nearest neighbor discovery, Super peer selection, Distribution tree construction »DNS-like system, where applications Send real-time performance queries and Receive information on desired metrics Without doing measurements by themselves 8
