Claim 6:
7. A method, comprising:
receiving, by a control plane device, a request for allocating a first Internet Protocol (IP) address to a first user;
allocating, by the control plane device and in response to receiving the request, the first IP address to the first user;
transmitting, by the control plane device, a response including the first IP address;
transmitting, by a forwarding plane device to the control plane device, the request, wherein by the forwarding plane device is applied to a broadband remote access server (BRAS) and is communicatively coupled to and separated from the control plane device;
receiving, by the forwarding plane device and from the control plane device, the response;
transmitting, by the forwarding plane device and to the first user, the first IP address to enable the first IP address to be included in a first data packet from the first user;
generating, by the control plane device, a forwarding rule, wherein the forwarding rule enables the forwarding plane device to forward a second data packet from a second user;
sending, by the control plane device and to the forwarding plane device, the forwarding rule;
receiving, by the forwarding plane device and from the second user, the second data packet comprising an identity of the second user; and
