semi-managed DHT METHOD FOR CONFIGURATION OF SEMI-MANAGED DHT BASED ON NDN AND SYSTEM THEREFOR

摘要

A method and system for configuring a semi-managed DHT are disclosed. The self-managed DHT configuration method includes: managing and sharing manager nodes that manage a plurality of data peer nodes for each group based on global information; dividing a keyspace area for each group of data peer nodes to create a sub-range segment step, distributing the sub-range segment to data peer nodes of a corresponding group, and managing the sub-range segment by the data peer node; monitoring, by manager nodes, the activity status of the data peer node for each group estimating the availability of the data peer nodes by analyzing and predicting the survival time of dynamically active data peer nodes; data for each sub-range segment based on the information service operation history of the data peer nodes and the survival time performing risk prediction to estimate availability and Sub-Range Management overhead, and based on the result of the risk prediction, Sub-Range Management Decision and global and performing a global stabilization decision required for system stabilization.
