METHOD FOR RESOURCE INFORMATION BACKUP OPERATION BASED ON PEER TO PEER NETWORK AND PEER TO PEER NETWORK THEREOF

摘要

The present invention provides a kind of method of resource information backup operation based on peer-to-peer network, include the following steps: that initiating the backup node that node is sent except determining range requests to connecting node in backup domain, wherein the backup node except the determining request range includes resource global identifier information by resource information backup, and the resource information saved on the backup domain and host node of connecting node is that have different domain identifiers; The backup domain of connecting node determine overseas backup node according to the backup rules except resource global identifier information and range, and by the overseas backup node of routing iinformation to initiate node; The backup operation request except node range of transmission is initiated to overseas backup node according to the routing iinformation, the backup node except above range is requested according to the overseas backup operation of alignment processing is implemented. The reliabilty and availability of this method and peer-to-peer network of the invention can better ensure that data.
