A communication control apparatus authenticates a user based on an authentication request transmitted from virtual Customer Premise Equipment (CPE) in response to a request of the user who accesses the virtual network. The communication control apparatus refers to information, held by an operation management system of a service operator, about the user of the virtual network. The communication control apparatus refers to information, collected by a collector, about a network slice constructed in the virtual network. The communication control apparatus selects a network slice through which data flow of the user. The communication control apparatus notifies the virtual CPE of the selected network slice.

Communication control device, communication control system, communication control method, and communication control program

There is provided a communication system for controlling a slice including a plurality of subslices. The system includes a temporary configuration unit configured to temporarily configure, for each subslice, a target value related to a service requirement, a measurement unit configured to acquire, in each subslice, a measurement value related to the service requirement for each QoS class and measure a margin, with respect to the target value, of the measurement value, a sharing unit configured to share the margin among the plurality of subslices, and an adjustment unit configured to smooth the margin among the plurality of subslices while satisfying the service requirement for the slice and configure, for each subslice, the target value and the QoS class corresponding to the margin after smoothing.
