Embodiment Construction

[0089] In the scenario where the user equipment accesses the network, figure 1 The network system shown can be a digital subscriber line (Digital Subscriber Line, DSL) access system, or an Ethernet (Ethernet) access system, of course, it can also be a passive optical network (Passive Optical Network, PON) access system system. Taking the scenario where the user equipment requests to obtain an IP address as an example, the access network system mainly includes user equipment, access equipment, IP edge equipment, DHCP server and other equipment. The user equipment communicates with the IP edge equipment and the DHCP server respectively through the access equipment. There can be one or more relay devices between the access device and the DHCP server, and the access device communicates with the DHCP server through one or more relay devices; the access device can also directly communicate with the DHCP server without passing through the relay device . The user equipment may be a ...

Abstract

The invention provides a data transmission method, a PNF SDN controller, a VNF SDN controller and a system. The data transmission method comprises the steps that: the PNF SDN controller receives a first message and an access loop identifier sent by a first network device; the PNF SDN controller generates a second message according to the access loop identifier and the first message; the PNF SDN controller sends the second message to the VNF SDN controller, so that the VNF SDN controller sends the second message to a second network device; the second message is used for requesting the second network device for distributing an IP address or an IP address prefix to the user device; and thus, the network device complexity is reduced.

Description

technical field [0001] The application relates to a data transmission method, a PNF SDN controller, a VNF SDN controller and a system. Background technique [0002] The network devices in the user access system may include user equipment, access devices, switches, or Internet Protocol (Internet Protocol, IP) edge devices. Take the processing and transmission of Dynamic Host Configuration Protocol (Dynamic Host Configuration Protocol, DHCP) message / Router Solicitation (Router Solicitation, RS) message as an example: [0003] The access device generates an access loop identifier after receiving the first DHCP / RS message sent by the user equipment, and adds the access loop identifier to the first DHCP / RS message to generate a second DHCP / RS message Then forward the second DHCP / RS message to the switch, so as to send the second DHCP / RS message to the DHCP server through the switch and Internet Protocol (Internet Protocol, IP) edge device, to request the DHCP server to assign th...
