Abstract: In a communication system, an SLG includes a slice selection unit that selects, in receiving a network slice reservation request including a network condition from a vCPE, based on topology information, a latency state, and processing capability information regarding each of the other SLGs, a destination SLG of a network slice that satisfies the network condition to reserve the network slice, and if there is no destination SLG that satisfies the network condition, newly activates a destination SLG to establish a network slice that satisfies the network condition, and an allocation unit that allocates traffic transmitted from the vCPE to the network slice reserved or established by the selection unit.

Abstract: 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.

Abstract: A storage unit (14) stores a terminal identifier for identifying a terminal, locator information indicating a transfer node to which a terminal is connected, a candidate terminal identifier for identifying a candidate terminal that is a communication destination candidate of the terminal, and candidate locator information indicating a transfer node to which the candidate terminal is connected in association with each other. An acquisition unit (15a) acquires, from a transfer node to which a terminal is newly connected, mapping information in which a locator information indicating the transfer node and a terminal identifier of the terminal are associated and stores the mapping information in the storage unit (14). A notification unit (15b) notifies the transfer node to which the terminal is newly connected of the candidate terminal identifier and the candidate locator information stored in association with the terminal identifier that is acquired in the storage unit (14).

Abstract: In a communication system. an SLG (6) includes a slice selection unit (614) that selects, in receiving a network slice reservation request including a network condition from a vCPE, based on topology information, a latency state, and processing capability information regarding each of the other SLGs (6), a destination SLG of a network slice that satisfies the network condition to reserve the network slice, and if there is no destination SLG that satisfies the network condition, newly activates a destination SLG to establish a network slice that satisfies the network condition, and an allocation unit (63) that allocates traffic transmitted from the vCPE to the network slice reserved or established by the selection unit.

Abstract: In a communication system (100), a collector (80) measures the usage condition in a service accommodated in a pre-generated default slice (20). Then, depending on the measured usage condition, the dispatching unit (40) dispatches the service accommodated in the default slice (20) to be accommodated in another new slice (30) separate from the default slice (20).

Abstract: An instance running device (10) determines, based on VNF instances through which a traffic flow passes and an order of software pieces through which the VNF instances pass, an order of the VNF instances to be migrated, and performs control so that the VNF instances are migrated to another instance running device (10) on the basis of the determined order of the software pieces migrated.

Abstract: A storage unit stores SLG information (12a) being information about a network slice to which an own device belongs, and an SLG table (12b) that aggregates SLG information (12a) about other SLGs (10). A table creation unit (11a) updates, when receiving SLG the information (12a) about the other SLGs (10) from an adjacent SLG (10), the SLG table (12b) by using the SLG information (12a). An SLG information transmission unit (11b) adds the SLG information (12a) about the own device to the received SLG information (12a), and transmits the SLG information (12a) to another adjacent SLG (10).
