Next generation Internet is highly concerned with the issue of trustworthy. An important foundation of trustworthy is authentication of the source IP address. With existing signature-and-verification based defense mechanisms, there is a lack of hierarchical architecture, which makes the structure of the trust alliance excessively flat and single. Moreover, with the increasing scale of trust alliances,...
Peer-to-peer file sharing systems, most notably Bit-Torrent (BT), have achieved tremendous success among Internet users. Recent studies suggest that the long-term relationships among BT peers can be explored to enhance the downloading performance; for example, the cooperation of peers to re-share old contents. However, whether such relationships can be built still remain unknown. In this paper, we...
The mapping of the Internet topological structure is indeed of great importance for a better understanding of the network's internal structure, network management, etc. Current explorations still mainly rely on the extensive use of the traceroute tool from a given set of sources to a given set of destinations. However, the deployment of dedicated measurement infrastructures on sources is often quite...
BitTorrent (BT) is an extremely successful peer-to-peer (P2P) application providing efficient file sharing over the Internet. The ever-increasing traffic among the peers has also put unprecedented pressure to Internet Service Providers (ISPs). P2P locality has therefore been widely suggested, which explores finding local resources to optimize the cross-ISP/AS traffic. However, the ISPs would fail...
