MULTIPLE ROUTING METHOD ON P2P NETWORK

摘要

A P2P network multiple routing method is provided to perform routing for collecting the location information of the specific file irrespective of the abnormality at a node for constructing a routing path. A first node in an m-bit identifier circle space selects the second node for transmitting the routing message in one's own finger table(S101). When a second node is selected, the first node transmits the routing message for requesting the location information of the specific files to the second node(S102). Thereafter, the first node confirms whether the transmission of the routing message fails(S103). If the transmission of the routing message fails, another node for receiving the routing message is selected in the finger table and the routing message is transmitted(S104). At the second node selection process, a key value is obtained by hashing the specific file as an object. The first node selects a node ID having the same value as one's own key value at the own finger table. The successor node having the selected node ID is selected as the second node.
