Referring to fig. 1, fig. 1 is a basic flow diagram of a multi-plane network access method provided by an embodiment of the present invention, and the specific steps are as follows:

s101, receiving a configuration protocol request message sent by a terminal, and sending a response message to the terminal, wherein the response message carries plane identifiers of at least two planes.

In the embodiment of the present invention, the terminal accesses the IPv6 network through the gateway to develop services, the bi-plane access is a common use scenario at present, and the following description specifically describes a method for providing the bi-plane access for the terminal by using the gateway as an example.

It should be understood that the terminal includes, but is not limited to, a smart set-top box, a mobile phone, a tablet computer, a notebook computer, and other user devices; the bi-plane refers to a network architecture in which an internet service plane and a video service plane are separated.

In the embodiment of the present invention, the adopted configuration protocols are two IPv6 address allocation protocols, namely, a Router Advertisement (RA) of an extended ICMPv6 and an extended DHCPv6, message interaction methods of the two protocols are different, and a biplane access mode is also different, in order to implement switching between the two modes, a terminal includes an RA client module and a DHCPv6 client module, and a gateway includes an RA service module and a DHCPv6 server module, which is specifically shown in fig. 2.

In the embodiment of the present invention, a process of a gateway interacting with a terminal through a DHCPv6 address assignment protocol, please refer to fig. 3, which specifically includes the following steps:

s303, the gateway receives a second request message sent by the terminal;

s304, the gateway sends a second response message to the terminal.

In step S301, in the DHCPv6 address assignment protocol, the first request message sent by the terminal is a Solicit request message, which is used to determine the location of the DHCPv6 server. In the embodiment of the present invention, the Solicit request packet carries an Option16, the Option16 fills a terminal special identifier, such as a "Smart STB" identifier, and the Option16 structure is shown in fig. 4.

In step S302, the gateway parses the terminal identification information, determines the terminal sending the first request packet, specifically, reads the "Smart STB" identification, and recognizes that the request is sent by the intelligent set-top box.

And the gateway then sends a first response message to the terminal, wherein in the DHCPv6 address allocation protocol, the first response message is an advertisement message and is used for responding to the Solicit request message and announcing that the DHCPv6 server can provide the DHCPv6 service. The advertisement message includes an Option X, the Option X carries a plane identifier specific to a plane, specifically, the plane identifier specific to a biplane is two pieces of IANA (reserved address) information, the first is an address of an internet plane, the second is an address of an IPTV plane, and a structure of the Option X in the advertisement message is shown in fig. 5, where a field from an identifier IAID _ internet to a field from an identifier IA _ NA-options _ internet is address information of the internet plane, and a field from an identifier IAID _ IPTV to a field from an identifier IA _ NA-options _ IPTV is address information of the IPTV plane.

It should be noted that the Option X is a new customized Option, and does not occupy the existing Option.

In step S303, the second Request message is a Request message, and is used to Request the DHCPv6 server for an IPv6 address and other configuration information; in step S304, the second response packet is a Reply packet. The Request message and the Reply message both carry the plane identifier of the plane to be accessed.

According to the DHCPv6 address allocation protocol specification, after the terminal and the gateway finish the Request message and the Reply message, the terminal generates access address information corresponding to the plane according to the plane identifier, and the access address information is used for the terminal to access different planes.

In the embodiment of the invention, after receiving the Route advertisement message, the terminal generates the access address information corresponding to the plane according to the plane identifier, and the access address information is used for the terminal to access different planes.

It should be noted that, before receiving a configuration protocol request message sent by a terminal, a gateway is connected to all plane routes, obtains a plane identifier of each plane, and generates a corresponding plane source identifier forwarding table according to the plane identifier of one of the planes. In the embodiment of the invention, the plane identifier is a PD prefix.
