Abstract: This invention provides an access-network device, a management device, a communication system, an information provision method, a management method, and a program that make it possible for the management device to acquire managed information being managed by the access-network device even if there is a node between the management device and the access-network device. The access-network device, which is incorporated into an access network, has a control unit and a communication unit. The control unit sets up a communication tunnel between the access-network device and the management device, which manages the access network, after the access-network device is incorporated into the access network. The communication unit uses the communication tunnel to transmit a layer 2 message containing information being managed by the access-network device.

Abstract: In order to accommodate expansion of a mobile network and detailed QoS control, a transmission VXLAN header is generated by setting a logical group to which an input packet belongs as a logical network number in the VNI field of a VXLAN header and setting QoS information as traffic control information in a predefined, predetermined field. The generated transmission VXLAN header is added to the input packet, which is then output as a VXLAN header-added output packet to a mobile backhaul. When a VXLAN header-added input packet is input from the mobile backhaul, the received VXLAN header that was added is removed, and the logical network number that is set in the VNI field of the received VXLAN header and the traffic control information that is set in the predefined, predetermined field are extracted. Traffic control is performed on the basis of the extracted logical network number and traffic control information, and the packet is output as an output packet.
