Abstract: Disclosed herein a method for configuration of semi-managed DHT based on NDN and system therefor. The method includes: managing and sharing manager nodes based on global information; generating a sub-range segment by partitioning a keyspace area, according to each group of the data peer nodes; managing the sub-range segment by distributing the sub-range segment corresponding to each group to data peer nodes of the each group; checking and analyzing liveness of the data peer node in the each group; estimating availability of the data peer nodes by predicting lifetime of data peer nodes through the checking and analyzing of liveliness; performing risk factor prediction that estimates data availability and sub-range management overhead; and performing a sub-range management decision at each of the manager nodes based on a result of the risk factor prediction, and performing a global stabilization decision required for global system stabilization.

Abstract: A protection switching management apparatus and method for effective use of resources in a multilayer or a multi-domain. The protection switching management method may include receiving an adaptation request from a network component included in an upper layer, determining whether to apply protection switching to a layer based on the received adaptation request, and setting a protection path in the layer based on a result of the determining.
