Problems solved by technology

[0007] The present invention provides a message sending method and device to at least solve the problem in the related art that the message carries the private network address of the terminal, and the network address translation from the private network address to the public network address needs to be performed when sending the message. Problems Affecting Network Speed

Embodiment Construction

[0027] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0028] The invention provides a message sending method, figure 1 is a flow chart of a message sending method according to an embodiment of the present invention, such as figure 1 As shown, the following steps S102 to S106 are included.

[0029] In step S102, the terminal and the CGN establish a GRE tunnel through the PPTP message exchange process.

[0030] Step S104, the terminal receives the public network address or the public network address and its port range allocated by the PPTP server module on the CGN.

[0031] In step S106, the terminal uses the public network address or the public network address and its port range to send subsequent messages to the CGN through the GRE tunnel.

Abstract

The invention discloses a message sending method and device. The method comprises the following steps: a GRE (Generic Routing Encapsulation) tunnel is set between a terminal and a CGN (Code Generation Network) through a PPTP (Point To Point Tunneling Protocol) message interaction process; the terminal receives a public network address distributed by a PPTP server module on the CGN or the public network address and a port range thereof; and the terminal uses the public network address or the public network address and the port range thereof to send a follow-up message to the CGN through the GRE tunnel. The public network address or the public network address and the port range thereof are directly distributed to the terminal, therefore network address translation on network equipment can be avoided, the network speed is increased, and the network quality is also increased.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a message sending method and device. Background technique [0002] At present, with the rapid development of network services, customers have higher and higher requirements for service quality. A Network Address Translation (NAT for short) service is a basic service currently addressing the lack of IPv4 addresses. [0003] The Point to Point Tunnel Protocol (PPTP for short) technology is currently supported on both Windows and Linux systems. As an advanced connection, PPTP technology enables users to access the company through tunnels in other places. [0004] Today, when IPv4 addresses are almost exhausted, NAT technology has spawned many RFC (Request For Comments) drafts, mainly focusing on various countermeasures in the process of v4 filtering to v6, such as NAT44, Dual-stack lite, NAT64, and NAT46. [0005] The NAT Port-range technology makes source tracing easier by spe...
