Embodiment Construction

[0035] The following combination Figure 1 to Figure 6 An embodiment of the present invention is described:

[0036] figure 1 It is a flowchart of a CGN device discovery method in an embodiment of the present invention. The method includes:

[0037] 102. The network device sends a message carrying the carrier-level network address translation (CGN) device information to the client device. The CGN device information includes CGN device type information and CGN device address information. The CGN device type information may be the conversion type information supported by the CGN device, or the tunnel type information supported by the CGN device, or both the conversion type information supported by the CGN device and the tunnel type information supported by the CGN device. For example, the network device may be a Dynamic Host Configuration Protocol (Dynamic Host Configuration Protocol, DHCP) server, a point-to-point protocol (point to point protocol, PPP) server or an IPv6 ro...

Abstract

The invention relates to the field of network communication, in particular to a carrier-grade network address translation (CGN) equipment discovery method, CGN equipment discovery equipment and a CGN equipment discovery system. The method comprises the step of: transmitting a message carrying CGN equipment information to client equipment, so that the client equipment establishes a tunnel with CGN equipment according to the CGN equipment information, wherein the CGN equipment information comprises the type information and address information of the CGN equipment. Through the technical scheme provided by the embodiment of the invention, as the network equipment transmits the message carrying the CGN equipment information to the client equipment, and the client equipment acquires the type information and address information of the CGN equipment and establishes the tunnel with the CGN equipment according to the CGN equipment information, the problem on CGN equipment discovery is solved.

Description

technical field [0001] The present invention relates to the field of network communication, in particular to a method, device and system for discovering carrier-level network address translation equipment. Background technique [0002] With the rapid popularization of network terminals, more and more network devices enter the Internet, requiring Internet Protocol (IP) addresses for communication, leading to the gradual exhaustion of currently used Internet Protocol version 4 (IPv4) IP addresses. The sixth version of the Internet Protocol (IPv6) has been considered as the core standard of the next generation Internet. [0003] Users who switch to IPv6 due to insufficient addresses hope to be able to access the current IPv4 normally, and because of the huge upgrade costs, it is difficult for existing IPv4 devices to upgrade to IPv6 immediately. Therefore, the evolution from IPv4 to IPv6 needs a long-term process. At present, the general view on this evolution process has chan...
