摘要: Through measurement study, we discover an interesting phenomenon, P2P address misconfiguration, in which a large number of peers send file downloading requests to "random" target on the Internet. measuring three datasets spanning four years and across five different /8 networks, find address-misconfigured traffic average contributes 38.9 percent Internet background radiation, increasing by more than 100 every year. To detect diagnose such unwanted traffic, design P2PScope, tool. After analyzing about 2 Tbytes data tracking millions peers, found that all systems, misconfiguration is caused resource mapping contamination: sources returned for given ID through indexing are not valid. Different systems have reasons contamination. For eMule, root cause mainly network byte-order problem eMule Source Exchange protocol. BitTorrent one reason anti-P2P companies actively inject bogus into system. Another KTorrent implementation has problem.
