We introduce a ¿bulk data transfer¿ (BDT) mechanism across multi-autonomous system (AS). The mechanism performance is limited by the positions of source or replica servers and by the inter/intra AS routing strategies. Therefore, a new mechanism is proposed to enable the source peer to create several virtual replica servers to transfer the data to the destination peer together. The mechanism works on the peer-to-peer (P2P) layer and can adapt to the changes of the lower networks. Evaluations by simulation and in a real network proved that the proposed mechanism can enhance the transfer performance and reliability.
