Problems solved by technology

[0004] However, the DS-Lite solution does not include the translation and intercommunication mechanism between IPv4 and IPv6, because the node's access to the IPv4 network and applications will be through IPv4, and the access to IPv6 network services and applications will be through IPv6; therefore, it cannot be implemented on the LAN side. Intercommunication between IPv4 network and WAN-side IPv4 network

Embodiment Construction

[0041] Various embodiments are described below according to the accompanying drawings. It should be noted that the content of the present invention can be explained by the following examples, but is not limited to the following examples.

[0042] Such as figure 1 As shown, it is a flow chart of the message processing method of the present invention, the method is described from the CPE side, and the method includes:

[0043] Step 101, the customer front-end equipment (CPE) obtains the address of the tunnel termination point, and establishes the tunnel by using DS-Lite;

[0044] The CPE can obtain the tunnel endpoint address through the Dynamic Host Configuration Protocol (DHCP) option, thereby establishing a tunnel such as an IPv4 in IPv6 tunnel;

[0045] Step 102, encapsulating the first packet uplinked by the local area network (LAN) side device into a second packet, and forwarding it to the bearer-level network device (CGN) through the above tunnel;

[0046] Wherein, the...

Abstract

The invention provides a message processing method, a message processing system and customer premises equipment, wherein the method includes: obtaining a tunnel endpoint address by the aid of a CPE (customer premises equipment) and building a tunnel by the aid of a DS (dual stack)-Lite; encapsulating a first up message of side equipment of an LAN (local area network) into a second message and transmitting the second message to a CGN (carrier-grade network) through the tunnel; and receiving the second message transmitted by the CGN through the tunnel, decapsulating the second message into the first message and transmitting the first message to the side equipment of the LAN. Mutual communication between two networks can be realized by the message processing method, the message processing system and the customer premises equipment.

Description

technical field [0001] The present invention relates to communication technology, in particular to a message processing method, system and user front-end equipment. Background technique [0002] The rapid development of the Internet has made the current IPv4 addresses increasingly exhausted, and the migration to IPv6 has become inevitable. During this migration process, the initial plan envisages that all network nodes, various application programs on the user side, and various application services on the server are simultaneously The dual-stack migration to IPv6, according to the current practice, this idea conflicts with the industrial business model, because the dual-stack technology itself also consumes IPv4 addresses, which leads to the exhaustion of IPv4 addresses in the process of implementing the dual-stack migration solution. will be resolved. Improved network address translation (NAT) 444 is the deployment of IPv4->IPv4 NAT on the operator's side. A large numbe...
