Abstract: Provided is a data analysis device comprising: an analysis subject acquisition part for acquiring data to be analyzed (analysis subject data); a precision estimation part for estimating the analysis precision of the analysis subject data; a selection part for selecting an analysis module to be used in analyzing the analysis subject data on the basis of the result of estimating the analysis precision of the analysis subject data and information indicating the analysis time of the analysis subject data; and an analysis execution part for analyzing the analysis subject data using the analysis module having been selected by the selection part. According to this configuration, in cases where a data analysis device configures a data analysis processing method, the operator of the data analysis device does not have to preset a determination standard for configuring the processing method.

Abstract: A management method and apparatus which allows easy management of virtual network function deployment on a network are provided. A network management apparatus generates an extended topology in which a virtual network function that can be deployed on a server is added as an extended node ((VNF(A), VNF(B)) to a topology of the network; and displays an optimum path (RP1, RP2, RP3) in the extended topology on display means (400b) when a requirement of at least one virtual network function and endpoint nodes involved in the requirement are input through an input means (401, 402), wherein the optimum path is obtained based on network resource information of the network and computing resource information of servers on which at least one virtual network function can be deployed.
